##### Issue submission checklist
|
|
||||||
|
|
||||||
- [ ] I report the issue, it's not a question
|
|
||||||
<!--
|
|
||||||
OpenCV team works with forum.opencv.org, Stack Overflow and other communities
|
|
||||||
to discuss problems. Tickets with questions without a real issue statement will be
|
|
||||||
closed.
|
|
||||||
-->
|
|
||||||
- [ ] I checked the problem with documentation, FAQ, open issues,
|
|
||||||
forum.opencv.org, Stack Overflow, etc and have not found any solution
|
|
||||||
<!--
|
|
||||||
Places to check:
|
|
||||||
* OpenCV documentation: https://docs.opencv.org
|
|
||||||
* FAQ page: https://github.com/opencv/opencv/wiki/FAQ
|
|
||||||
* OpenCV forum: https://forum.opencv.org
|
|
||||||
* OpenCV issue tracker: https://github.com/opencv/opencv/issues?q=is%3Aissue
|
|
||||||
* Stack Overflow branch: https://stackoverflow.com/questions/tagged/opencv
|
|
||||||
-->
|
|
||||||
- [ ] I updated to the latest OpenCV version and the issue is still there
|
|
||||||
<!--
|
|
||||||
master branch for OpenCV 4.x and 3.4 branch for OpenCV 3.x releases.
|
|
||||||
OpenCV team supports only the latest release for each branch.
|
|
||||||
The ticket is closed if the problem is not reproduced with the modern version.
|
|
||||||
-->
|
|
||||||
- [ ] There is reproducer code and related data files: videos, images, onnx, etc
|
|
||||||
<!--
|
|
||||||
The best reproducer -- test case for OpenCV that we can add to the library.
|
|
||||||
Recommendations for media files and binary files:
|
|
||||||
* Try to reproduce the issue with images and videos in opencv_extra repository
|
|
||||||
to reduce attachment size
|
|
||||||
* Use PNG for images, if you report some CV related bug, but not image reader
|
|
||||||
issue
|
|
||||||
* Attach the image as an archive to the ticket, if you report some reader issue.
|
|
||||||
Image hosting services compress images and it breaks the repro code.
|
|
||||||
* Provide ONNX file for some public model or ONNX file with random weights,
|
|
||||||
if you report ONNX parsing or handling issue. Architecture details diagram
|
|
||||||
from netron tool can be very useful too. See https://lutzroeder.github.io/netron/

This is generator of CLapack subset.
|
|
||||||
The usage:
|
|
||||||
|
|
||||||
1. Make sure you have the special version of f2c installed.
|
|
||||||
Grab it from https://github.com/vpisarev/f2c/tree/for_lapack.
|
|
||||||
2. Download fresh version of Lapack from
|
|
||||||
https://github.com/Reference-LAPACK/lapack.
|
|
||||||
You may choose some specific version or the latest snapshot.
|
|
||||||
3. If necessary, edit "roots" and "banlist" variables in this script, specify the needed and unneeded functions
|
|
||||||
4. From within a working directory run
|
|
||||||
|
|
||||||
$ python3 <opencv_root>/3rdparty/clapack/make_clapack.py <lapack_root>
|
|
||||||
or
|
|
||||||
$ F2C=<path_to_custom_f2c> python3 <opencv_root>/3rdparty/clapack/make_clapack.py <lapack_root>
|
|
||||||
|
|
||||||
it will generate "new_clapack" directory with "include" and "src" subdirectories.
|
|
||||||
5. erase opencv/3rdparty/clapack/src and replace it with new_clapack/src.
|
|
||||||
6. copy new_clapack/include/lapack.h to opencv/3rdparty/clapack/include.
|
|
||||||
7. optionally, edit opencv/3rdparty/clapack/CMakeLists.txt and update CLAPACK_VERSION as needed.
|
|
||||||
|
|
||||||
This is it. Now build it and enjoy.

* be set whenever VFPv3 is set too.
|
|
||||||
*
|
|
||||||
* ARMv7:
|
|
||||||
* CPU supports the ARMv7-A basic instruction set.
|
|
||||||
* This feature is mandated by the 'armeabi-v7a' ABI.
|
|
||||||
*
|
|
||||||
* VFPv3:
|
|
||||||
* CPU supports the VFPv3-D16 instruction set, providing hardware FPU
|
|
||||||
* support for single and double precision floating point registers.
|
|
||||||
* Note that only 16 FPU registers are available by default, unless
|
|
||||||
* the D32 bit is set too. This feature is also mandated by the
|
|
||||||
* 'armeabi-v7a' ABI.
|
|
||||||
*
|
|
||||||
* VFP_D32:
|
|
||||||
* CPU VFP optional extension that provides 32 FPU registers,
|
|
||||||
* instead of 16. Note that ARM mandates this feature is the 'NEON'
|
|
||||||
* feature is implemented by the CPU.
|
|
||||||
*
|
|
||||||
* NEON:
|
|
||||||
* CPU FPU supports "ARM Advanced SIMD" instructions, also known as
|
|
||||||
* NEON. Note that this mandates the VFP_D32 feature as well, per the
|
|
||||||
* ARM Architecture specification.
|
|
||||||
*
|
|
||||||
* VFP_FP16:
|
|
||||||
* Half-width floating precision VFP extension. If set, the CPU
|
|
||||||
* supports instructions to perform floating-point operations on
|
|
||||||
* 16-bit registers. This is part of the VFPv4 specification, but
|
|
||||||
* not mandated by any Android ABI.
|
|
||||||
*
|
|
||||||
* VFP_FMA:
|
|
||||||
* Fused multiply-accumulate VFP instructions extension. Also part of
|
|
||||||
* the VFPv4 specification, but not mandated by any Android ABI.
|
|
||||||
*
|
|
||||||
* NEON_FMA:
|
|
||||||
* Fused multiply-accumulate NEON instructions extension. Optional
|
|
||||||
* extension from the VFPv4 specification, but not mandated by any
|
|
||||||
* Android ABI.
|
|
||||||
*
|
|
||||||
* IDIV_ARM:
|
|
||||||
* Integer division available in ARM mode. Only available
|
|
||||||
* on recent CPUs (e.g. Cortex-A15).
|
|
||||||
*
|
|
||||||
* IDIV_THUMB2:
|
|
||||||
* Integer division available in Thumb-2 mode. Only available
|
|
||||||
* on recent CPUs (e.g. Cortex-A15).
|
|
||||||
*
|
|
||||||
* iWMMXt:
|
|
||||||
* Optional extension that adds MMX registers and operations to an
|
|
||||||
* ARM CPU. This is only available on a few XScale-based CPU designs
|
|
||||||
* sold by Marvell. Pretty rare in practice.
|
|
||||||
*
|
|
||||||
* AES:
|
|
||||||
* CPU supports AES instructions. These instructions are only
|
|
||||||
* available for 32-bit applications running on ARMv8 CPU.
|
|
||||||
*
|
|
||||||
* CRC32:
|
|
||||||
* CPU supports CRC32 instructions. These instructions are only
|
|
||||||
* available for 32-bit applications running on ARMv8 CPU.
|
|
||||||
*
|
|
||||||
* SHA2:
|
|
||||||
* CPU supports SHA2 instructions. These instructions are only
|
|
||||||
* available for 32-bit applications running on ARMv8 CPU.
|
|
||||||
*
|
|
||||||
* SHA1:
|
|
||||||
* CPU supports SHA1 instructions. These instructions are only
|
|
||||||
* available for 32-bit applications running on ARMv8 CPU.
|
|
||||||
*
|
|
||||||
* PMULL:
|
|
||||||
* CPU supports 64-bit PMULL and PMULL2 instructions. These
|
|
||||||
* instructions are only available for 32-bit applications
|
|
||||||
* running on ARMv8 CPU.
|
|
||||||
*
|
|
||||||
* If you want to tell the compiler to generate code that targets one of
|
|
||||||
* the feature set above, you should probably use one of the following
|
|
||||||
* flags (for more details, see technical note at the end of this file):
|
|
||||||
*
|
|
||||||
* -mfpu=vfp
|
|
||||||
* -mfpu=vfpv2
|
|
||||||
* These are equivalent and tell GCC to use VFPv2 instructions for
|
|
||||||
* floating-point operations. Use this if you want your code to
|
|
||||||
* run on *some* ARMv6 devices, and any ARMv7-A device supported
|
|
||||||
* by Android.
|
|
||||||
*
|
|
||||||
* Generated code requires VFPv2 feature.
|
|
||||||
*
|
|
||||||
* -mfpu=vfpv3-d16
|
|
||||||
* Tell GCC to use VFPv3 instructions (using only 16 FPU registers).
|
|
||||||
* This should be generic code that runs on any CPU that supports the
|
|
||||||
* 'armeabi-v7a' Android ABI. Note that no ARMv6 CPU supports this.
|
|
||||||
*
|
|
||||||
* Generated code requires VFPv3 feature.
|
|
||||||
*
|
|
||||||
* -mfpu=vfpv3
|
|
||||||
* Tell GCC to use VFPv3 instructions with 32 FPU registers.
|
|
||||||
* Generated code requires VFPv3|VFP_D32 features.
|
|
||||||
*
|
|
||||||
* -mfpu=neon
|
|
||||||
* Tell GCC to use VFPv3 instructions with 32 FPU registers, and
|
|
||||||
* also support NEON intrinsics (see <arm_neon.h>).
|
|
||||||
* Generated code requires VFPv3|VFP_D32|NEON features.
|
|
||||||
*
|
|
||||||
* -mfpu=vfpv4-d16
|
|
||||||
* Generated code requires VFPv3|VFP_FP16|VFP_FMA features.
|
|
||||||
*
|
|
||||||
* -mfpu=vfpv4
|
|
||||||
* Generated code requires VFPv3|VFP_FP16|VFP_FMA|VFP_D32 features.
|
|
||||||
*
|
|
||||||
* -mfpu=neon-vfpv4
|
|
||||||
* Generated code requires VFPv3|VFP_FP16|VFP_FMA|VFP_D32|NEON|NEON_FMA
|
|
||||||
* features.
|
|
||||||
*
|
|
||||||
* -mcpu=cortex-a7
|
|
||||||
* -mcpu=cortex-a15
|
|
||||||
* Generated code requires VFPv3|VFP_FP16|VFP_FMA|VFP_D32|
|
|
||||||
* NEON|NEON_FMA|IDIV_ARM|IDIV_THUMB2
|
|
||||||
* This flag implies -mfpu=neon-vfpv4.
|
|
||||||
*
|
|
||||||
* -mcpu=iwmmxt
|
|
||||||
* Allows the use of iWMMXt instrinsics with GCC.
|
|
||||||
*
|
|
||||||
* IMPORTANT NOTE: These flags should only be tested when
|
|
||||||
* android_getCpuFamily() returns ANDROID_CPU_FAMILY_ARM, i.e. this is a
|
|
||||||
* 32-bit process.
|
|
||||||
*
|
|
||||||
* When running a 64-bit ARM process on an ARMv8 CPU,
|
|
||||||
* android_getCpuFeatures() will return a different set of bitflags

[This is the first released version of the Lesser GPL. It also counts
|
|
||||||
as the successor of the GNU Library Public License, version 2, hence
|
|
||||||
the version number 2.1.]
|
|
||||||
|
|
||||||
Preamble
|
|
||||||
|
|
||||||
The licenses for most software are designed to take away your
|
|
||||||
freedom to share and change it. By contrast, the GNU General Public
|
|
||||||
Licenses are intended to guarantee your freedom to share and change
|
|
||||||
free software--to make sure the software is free for all its users.
|
|
||||||
|
|
||||||
This license, the Lesser General Public License, applies to some
|
|
||||||
specially designated software packages--typically libraries--of the
|
|
||||||
Free Software Foundation and other authors who decide to use it. You
|
|
||||||
can use it too, but we suggest you first think carefully about whether
|
|
||||||
this license or the ordinary General Public License is the better
|
|
||||||
strategy to use in any particular case, based on the explanations below.
|
|
||||||
|
|
||||||
When we speak of free software, we are referring to freedom of use,
|
|
||||||
not price. Our General Public Licenses are designed to make sure that
|
|
||||||
you have the freedom to distribute copies of free software (and charge
|
|
||||||
for this service if you wish); that you receive source code or can get
|
|
||||||
it if you want it; that you can change the software and use pieces of
|
|
||||||
it in new free programs; and that you are informed that you can do
|
|
||||||
these things.
|
|
||||||
|
|
||||||
To protect your rights, we need to make restrictions that forbid
|
|
||||||
distributors to deny you these rights or to ask you to surrender these
|
|
||||||
rights. These restrictions translate to certain responsibilities for
|
|
||||||
you if you distribute copies of the library or if you modify it.
|
|
||||||
|
|
||||||
For example, if you distribute copies of the library, whether gratis
|
|
||||||
or for a fee, you must give the recipients all the rights that we gave
|
|
||||||
you. You must make sure that they, too, receive or can get the source
|
|
||||||
code. If you link other code with the library, you must provide
|
|
||||||
complete object files to the recipients, so that they can relink them
|
|
||||||
with the library after making changes to the library and recompiling
|
|
||||||
it. And you must show them these terms so they know their rights.
|
|
||||||
|
|
||||||
We protect your rights with a two-step method: (1) we copyright the
|
|
||||||
library, and (2) we offer you this license, which gives you legal
|
|
||||||
permission to copy, distribute and/or modify the library.
|
|
||||||
|
|
||||||
To protect each distributor, we want to make it very clear that
|
|
||||||
there is no warranty for the free library. Also, if the library is
|
|
||||||
modified by someone else and passed on, the recipients should know
|
|
||||||
that what they have is not the original version, so that the original
|
|
||||||
author's reputation will not be affected by problems that might be
|
|
||||||
introduced by others.
|
|
||||||
|
|
||||||
Finally, software patents pose a constant threat to the existence of
|
|
||||||
any free program. We wish to make sure that a company cannot
|
|
||||||
effectively restrict the users of a free program by obtaining a
|
|
||||||
restrictive license from a patent holder. Therefore, we insist that
|
|
||||||
any patent license obtained for a version of the library must be
|
|
||||||
consistent with the full freedom of use specified in this license.
|
|
||||||
|
|
||||||
Most GNU software, including some libraries, is covered by the
|
|
||||||
ordinary GNU General Public License. This license, the GNU Lesser
|
|
||||||
General Public License, applies to certain designated libraries, and
|
|
||||||
is quite different from the ordinary General Public License. We use
|
|
||||||
this license for certain libraries in order to permit linking those
|
|
||||||
libraries into non-free programs.
|
|
||||||
|
|
||||||
When a program is linked with a library, whether statically or using
|
|
||||||
a shared library, the combination of the two is legally speaking a
|
|
||||||
combined work, a derivative of the original library. The ordinary
|
|
||||||
General Public License therefore permits such linking only if the
|
|
||||||
entire combination fits its criteria of freedom. The Lesser General
|
|
||||||
Public License permits more lax criteria for linking other code with
|
|
||||||
the library.
|
|
||||||
|
|
||||||
We call this license the "Lesser" General Public License because it
|
|
||||||
does Less to protect the user's freedom than the ordinary General
|
|
||||||
Public License. It also provides other free software developers Less
|
|
||||||
of an advantage over competing non-free programs. These disadvantages
|
|
||||||
are the reason we use the ordinary General Public License for many
|
|
||||||
libraries. However, the Lesser license provides advantages in certain
|
|
||||||
special circumstances.
|
|
||||||
|
|
||||||
For example, on rare occasions, there may be a special need to
|
|
||||||
encourage the widest possible use of a certain library, so that it becomes
|
|
||||||
a de-facto standard. To achieve this, non-free programs must be
|
|
||||||
allowed to use the library. A more frequent case is that a free
|
|
||||||
library does the same job as widely used non-free libraries. In this
|
|
||||||
case, there is little to gain by limiting the free library to free
|
|
||||||
software only, so we use the Lesser General Public License.
|
|
||||||
|
|
||||||
In other cases, permission to use a particular library in non-free
|
|
||||||
programs enables a greater number of people to use a large body of
|
|
||||||
free software. For example, permission to use the GNU C Library in
|
|
||||||
non-free programs enables many more people to use the whole GNU
|
|
||||||
operating system, as well as its variant, the GNU/Linux operating
|
|
||||||
system.
|
|
||||||
|
|
||||||
Although the Lesser General Public License is Less protective of the
|
|
||||||
users' freedom, it does ensure that the user of a program that is
|
|
||||||
linked with the Library has the freedom and the wherewithal to run
|
|
||||||
that program using a modified version of the Library.
|
|
||||||
|
|
||||||
The precise terms and conditions for copying, distribution and
|
|
||||||
modification follow. Pay close attention to the difference between a
|
|
||||||
"work based on the library" and a "work that uses the library". The
|
|
||||||
former contains code derived from the library, whereas the latter must
|
|
||||||
be combined with the library in order to run.
|
|
||||||

|
||||||
GNU LESSER GENERAL PUBLIC LICENSE
|
|
||||||
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
|
|
||||||
|
|
||||||
0. This License Agreement applies to any software library or other
|
|
||||||
program which contains a notice placed by the copyright holder or
|
|
||||||
other authorized party saying it may be distributed under the terms of
|
|
||||||
this Lesser General Public License (also called "this License").
|
|
||||||
Each licensee is addressed as "you".
|
|
||||||
|
|
||||||
A "library" means a collection of software functions and/or data
|
|
||||||
prepared so as to be conveniently linked with application programs
|
|
||||||
(which use some of those functions and data) to form executables.
|
|
||||||
|
|
||||||
The "Library", below, refers to any such software library or work
|
|
||||||
which has been distributed under these terms. A "work based on the
|
|
||||||
Library" means either the Library or any derivative work under
|
|
||||||
copyright law: that is to say, a work containing the Library or a
|
|
||||||
portion of it, either verbatim or with modifications and/or translated
|
|
||||||
straightforwardly into another language. (Hereinafter, translation is
|
|
||||||
included without limitation in the term "modification".)
|
|
||||||
|
|
||||||
"Source code" for a work means the preferred form of the work for
|
|
||||||
making modifications to it. For a library, complete source code means
|
|
||||||
all the source code for all modules it contains, plus any associated
|
|
||||||
interface definition files, plus the scripts used to control compilation
|
|
||||||
and installation of the library.
|
|
||||||
|
|
||||||
Activities other than copying, distribution and modification are not
|
|
||||||
covered by this License; they are outside its scope. The act of
|
|
||||||
running a program using the Library is not restricted, and output from
|
|
||||||
such a program is covered only if its contents constitute a work based
|
|
||||||
on the Library (independent of the use of the Library in a tool for
|
|
||||||
writing it). Whether that is true depends on what the Library does
|
|
||||||
and what the program that uses the Library does.
|
|
||||||
|
|
||||||
1. You may copy and distribute verbatim copies of the Library's
|
|
||||||
complete source code as you receive it, in any medium, provided that
|
|
||||||
you conspicuously and appropriately publish on each copy an
|
|
||||||
appropriate copyright notice and disclaimer of warranty; keep intact
|
|
||||||
all the notices that refer to this License and to the absence of any
|
|
||||||
warranty; and distribute a copy of this License along with the
|
|
||||||
Library.
|
|
||||||
|
|
||||||
You may charge a fee for the physical act of transferring a copy,
|
|
||||||
and you may at your option offer warranty protection in exchange for a
|
|
||||||
fee.
|
|
||||||
|
|
||||||
2. You may modify your copy or copies of the Library or any portion
|
|
||||||
of it, thus forming a work based on the Library, and copy and
|
|
||||||
distribute such modifications or work under the terms of Section 1
|
|
||||||
above, provided that you also meet all of these conditions:
|
|
||||||
|
|
||||||
a) The modified work must itself be a software library.
|
|
||||||
|
|
||||||
b) You must cause the files modified to carry prominent notices
|
|
||||||
stating that you changed the files and the date of any change.
|
|
||||||
|
|
||||||
c) You must cause the whole of the work to be licensed at no
|
|
||||||
charge to all third parties under the terms of this License.
|
|
||||||
|
|
||||||
d) If a facility in the modified Library refers to a function or a
|
|
||||||
table of data to be supplied by an application program that uses
|
|
||||||
the facility, other than as an argument passed when the facility
|
|
||||||
is invoked, then you must make a good faith effort to ensure that,
|
|
||||||
in the event an application does not supply such function or
|
|
||||||
table, the facility still operates, and performs whatever part of
|
|
||||||
its purpose remains meaningful.
|
|
||||||
|
|
||||||
(For example, a function in a library to compute square roots has
|
|
||||||
a purpose that is entirely well-defined independent of the
|
|
||||||
application. Therefore, Subsection 2d requires that any
|
|
||||||
application-supplied function or table used by this function must
|
|
||||||
be optional: if the application does not supply it, the square
|
|
||||||
root function must still compute square roots.)
|
|
||||||
|
|
||||||
These requirements apply to the modified work as a whole. If
|
|
||||||
identifiable sections of that work are not derived from the Library,
|
|
||||||
and can be reasonably considered independent and separate works in
|
|
||||||
themselves, then this License, and its terms, do not apply to those
|
|
||||||
sections when you distribute them as separate works. But when you
|
|
||||||
distribute the same sections as part of a whole which is a work based
|
|
||||||
on the Library, the distribution of the whole must be on the terms of
|
|
||||||
this License, whose permissions for other licensees extend to the
|
|
||||||
entire whole, and thus to each and every part regardless of who wrote
|
|
||||||
it.
|
|
||||||
|
|
||||||
Thus, it is not the intent of this section to claim rights or contest
|
|
||||||
your rights to work written entirely by you; rather, the intent is to
|
|
||||||
exercise the right to control the distribution of derivative or
|
|
||||||
collective works based on the Library.
|
|
||||||
|
|
||||||
In addition, mere aggregation of another work not based on the Library
|
|
||||||
with the Library (or with a work based on the Library) on a volume of
|
|
||||||
a storage or distribution medium does not bring the other work under
|
|
||||||
the scope of this License.
|
|
||||||
|
|
||||||
3. You may opt to apply the terms of the ordinary GNU General Public
|
|
||||||
License instead of this License to a given copy of the Library. To do
|
|
||||||
this, you must alter all the notices that refer to this License, so
|
|
||||||
that they refer to the ordinary GNU General Public License, version 2,
|
|
||||||
instead of to this License. (If a newer version than version 2 of the
|
|
||||||
ordinary GNU General Public License has appeared, then you can specify
|
|
||||||
that version instead if you wish.) Do not make any other change in
|
|
||||||
these notices.
|
|
||||||
|
|
||||||
Once this change is made in a given copy, it is irreversible for
|
|
||||||
that copy, so the ordinary GNU General Public License applies to all
|
|
||||||
subsequent copies and derivative works made from that copy.
|
|
||||||
|
|
||||||
This option is useful when you wish to copy part of the code of
|
|
||||||
the Library into a program that is not a library.
|
|
||||||
|
|
||||||
4. You may copy and distribute the Library (or a portion or
|
|
||||||
derivative of it, under Section 2) in object code or executable form
|
|
||||||
under the terms of Sections 1 and 2 above provided that you accompany
|
|
||||||
it with the complete corresponding machine-readable source code, which
|
|
||||||
must be distributed under the terms of Sections 1 and 2 above on a
|
|
||||||
medium customarily used for software interchange.
|
|
||||||
|
|
||||||
If distribution of object code is made by offering access to copy
|
|
||||||
from a designated place, then offering equivalent access to copy the
|
|
||||||
source code from the same place satisfies the requirement to
|
|
||||||
distribute the source code, even though third parties are not
|
|
||||||
compelled to copy the source along with the object code.
|
|
||||||
|
|
||||||
5. A program that contains no derivative of any portion of the
|
|
||||||
Library, but is designed to work with the Library by being compiled or
|
|
||||||
linked with it, is called a "work that uses the Library". Such a
|
|
||||||
work, in isolation, is not a derivative work of the Library, and
|
|
||||||
therefore falls outside the scope of this License.
|
|
||||||
|
|
||||||
However, linking a "work that uses the Library" with the Library
|
|
||||||
creates an executable that is a derivative of the Library (because it
|
|
||||||
contains portions of the Library), rather than a "work that uses the
|
|
||||||
library". The executable is therefore covered by this License.
|
|
||||||
Section 6 states terms for distribution of such executables.
|
|
||||||
|
|
||||||
When a "work that uses the Library" uses material from a header file
|
|
||||||
that is part of the Library, the object code for the work may be a
|
|
||||||
derivative work of the Library even though the source code is not.
|
|
||||||
Whether this is true is especially significant if the work can be
|
|
||||||
linked without the Library, or if the work is itself a library. The
|
|
||||||
threshold for this to be true is not precisely defined by law.
|
|
||||||
|
|
||||||
If such an object file uses only numerical parameters, data
|
|
||||||
structure layouts and accessors, and small macros and small inline
|
|
||||||
functions (ten lines or less in length), then the use of the object
|
|
||||||
file is unrestricted, regardless of whether it is legally a derivative
|
|
||||||
work. (Executables containing this object code plus portions of the
|
|
||||||
Library will still fall under Section 6.)
|
|
||||||
|
|
||||||
Otherwise, if the work is a derivative of the Library, you may
|
|
||||||
distribute the object code for the work under the terms of Section 6.
|
|
||||||
Any executables containing that work also fall under Section 6,
|
|
||||||
whether or not they are linked directly with the Library itself.
|
|
||||||
|
|
||||||
6. As an exception to the Sections above, you may also combine or
|
|
||||||
link a "work that uses the Library" with the Library to produce a
|
|
||||||
work containing portions of the Library, and distribute that work
|
|
||||||
under terms of your choice, provided that the terms permit
|
|
||||||
modification of the work for the customer's own use and reverse
|
|
||||||
engineering for debugging such modifications.
|
|
||||||
|
|
||||||
You must give prominent notice with each copy of the work that the
|
|
||||||
Library is used in it and that the Library and its use are covered by
|
|
||||||
this License. You must supply a copy of this License. If the work
|
|
||||||
during execution displays copyright notices, you must include the
|
|
||||||
copyright notice for the Library among them, as well as a reference
|
|
||||||
directing the user to the copy of this License. Also, you must do one
|
|
||||||
of these things:
|
|
||||||
|
|
||||||
a) Accompany the work with the complete corresponding
|
|
||||||
machine-readable source code for the Library including whatever
|
|
||||||
changes were used in the work (which must be distributed under
|
|
||||||
Sections 1 and 2 above); and, if the work is an executable linked
|
|
||||||
with the Library, with the complete machine-readable "work that
|
|
||||||
uses the Library", as object code and/or source code, so that the
|
|
||||||
user can modify the Library and then relink to produce a modified
|
|
||||||
executable containing the modified Library. (It is understood
|
|
||||||
that the user who changes the contents of definitions files in the
|
|
||||||
Library will not necessarily be able to recompile the application
|
|
||||||
to use the modified definitions.)
|
|
||||||
|
|
||||||
b) Use a suitable shared library mechanism for linking with the
|
|
||||||
Library. A suitable mechanism is one that (1) uses at run time a
|
|
||||||
copy of the library already present on the user's computer system,
|
|
||||||
rather than copying library functions into the executable, and (2)
|
|
||||||
will operate properly with a modified version of the library, if
|
|
||||||
the user installs one, as long as the modified version is
|
|
||||||
interface-compatible with the version that the work was made with.
|
|
||||||
|
|
||||||
c) Accompany the work with a written offer, valid for at
|
|
||||||
least three years, to give the same user the materials
|
|
||||||
specified in Subsection 6a, above, for a charge no more
|
|
||||||
than the cost of performing this distribution.
|
|
||||||
|
|
||||||
d) If distribution of the work is made by offering access to copy
|
|
||||||
from a designated place, offer equivalent access to copy the above
|
|
||||||
specified materials from the same place.
|
|
||||||
|
|
||||||
e) Verify that the user has already received a copy of these
|
|
||||||
materials or that you have already sent this user a copy.
|
|
||||||
|
|
||||||
For an executable, the required form of the "work that uses the
|
|
||||||
Library" must include any data and utility programs needed for
|
|
||||||
reproducing the executable from it. However, as a special exception,
|
|
||||||
the materials to be distributed need not include anything that is
|
|
||||||
normally distributed (in either source or binary form) with the major
|
|
||||||
components (compiler, kernel, and so on) of the operating system on
|
|
||||||
which the executable runs, unless that component itself accompanies
|
|
||||||
the executable.
|
|
||||||
|
|
||||||
It may happen that this requirement contradicts the license
|
|
||||||
restrictions of other proprietary libraries that do not normally
|
|
||||||
accompany the operating system. Such a contradiction means you cannot
|
|
||||||
use both them and the Library together in an executable that you
|
|
||||||
distribute.
|
|
||||||
|
|
||||||
7. You may place library facilities that are a work based on the
|
|
||||||
Library side-by-side in a single library together with other library
|
|
||||||
facilities not covered by this License, and distribute such a combined
|
|
||||||
library, provided that the separate distribution of the work based on
|
|
||||||
the Library and of the other library facilities is otherwise
|
|
||||||
permitted, and provided that you do these two things:
|
|
||||||
|
|
||||||
a) Accompany the combined library with a copy of the same work
|
|
||||||
based on the Library, uncombined with any other library
|
|
||||||
facilities. This must be distributed under the terms of the
|
|
||||||
Sections above.
|
|
||||||
|
|
||||||
b) Give prominent notice with the combined library of the fact
|
|
||||||
that part of it is a work based on the Library, and explaining
|
|
||||||
where to find the accompanying uncombined form of the same work.
|
|
||||||
|
|
||||||
8. You may not copy, modify, sublicense, link with, or distribute
|
|
||||||
the Library except as expressly provided under this License. Any
|
|
||||||
attempt otherwise to copy, modify, sublicense, link with, or
|
|
||||||
distribute the Library is void, and will automatically terminate your
|
|
||||||
rights under this License. However, parties who have received copies,
|
|
||||||
or rights, from you under this License will not have their licenses
|
|
||||||
terminated so long as such parties remain in full compliance.
|
|
||||||
|
|
||||||
9. You are not required to accept this License, since you have not
|
|
||||||
signed it. However, nothing else grants you permission to modify or
|
|
||||||
distribute the Library or its derivative works. These actions are
|
|
||||||
prohibited by law if you do not accept this License. Therefore, by
|
|
||||||
modifying or distributing the Library (or any work based on the
|
|
||||||
Library), you indicate your acceptance of this License to do so, and
|
|
||||||
all its terms and conditions for copying, distributing or modifying
|
|
||||||
the Library or works based on it.
|
|
||||||
|
|
||||||
10. Each time you redistribute the Library (or any work based on the
|
|
||||||
Library), the recipient automatically receives a license from the
|
|
||||||
original licensor to copy, distribute, link with or modify the Library
|
|
||||||
subject to these terms and conditions. You may not impose any further
|
|
||||||
restrictions on the recipients' exercise of the rights granted herein.
|
|
||||||
You are not responsible for enforcing compliance by third parties with
|
|
||||||
this License.
|
|
||||||
|
|
||||||
11. If, as a consequence of a court judgment or allegation of patent
|
|
||||||
infringement or for any other reason (not limited to patent issues),
|
|
||||||
conditions are imposed on you (whether by court order, agreement or
|
|
||||||
otherwise) that contradict the conditions of this License, they do not
|
|
||||||
excuse you from the conditions of this License. If you cannot
|
|
||||||
distribute so as to satisfy simultaneously your obligations under this
|
|
||||||
License and any other pertinent obligations, then as a consequence you
|
|
||||||
may not distribute the Library at all. For example, if a patent
|
|
||||||
license would not permit royalty-free redistribution of the Library by
|
|
||||||
all those who receive copies directly or indirectly through you, then
|
|
||||||
the only way you could satisfy both it and this License would be to
|
|
||||||
refrain entirely from distribution of the Library.
|
|
||||||
|
|
||||||
If any portion of this section is held invalid or unenforceable under any
|
|
||||||
particular circumstance, the balance of the section is intended to apply,
|
|
||||||
and the section as a whole is intended to apply in other circumstances.
|
|
||||||
|
|
||||||
It is not the purpose of this section to induce you to infringe any
|
|
||||||
patents or other property right claims or to contest validity of any
|
|
||||||
such claims; this section has the sole purpose of protecting the
|
|
||||||
integrity of the free software distribution system which is
|
|
||||||
implemented by public license practices. Many people have made
|
|
||||||
generous contributions to the wide range of software distributed
|
|
||||||
through that system in reliance on consistent application of that
|
|
||||||
system; it is up to the author/donor to decide if he or she is willing
|
|
||||||
to distribute software through any other system and a licensee cannot
|
|
||||||
impose that choice.
|
|
||||||
|
|
||||||
This section is intended to make thoroughly clear what is believed to
|
|
||||||
be a consequence of the rest of this License.
|
|
||||||
|
|
||||||
12. If the distribution and/or use of the Library is restricted in
|
|
||||||
certain countries either by patents or by copyrighted interfaces, the
|
|
||||||
original copyright holder who places the Library under this License may add
|
|
||||||
an explicit geographical distribution limitation excluding those countries,
|
|
||||||
so that distribution is permitted only in or among countries not thus
|
|
||||||
excluded. In such case, this License incorporates the limitation as if
|
|
||||||
written in the body of this License.
|
|
||||||
|
|
||||||
13. The Free Software Foundation may publish revised and/or new
|
|
||||||
versions of the Lesser General Public License from time to time.
|
|
||||||
Such new versions will be similar in spirit to the present version,
|
|
||||||
but may differ in detail to address new problems or concerns.
|
|
||||||
|
|
||||||
Each version is given a distinguishing version number. If the Library
|
|
||||||
specifies a version number of this License which applies to it and
|
|
||||||
"any later version", you have the option of following the terms and
|
|
||||||
conditions either of that version or of any later version published by
|
|
||||||
the Free Software Foundation. If the Library does not specify a
|
|
||||||
license version number, you may choose any version ever published by
|
|
||||||
the Free Software Foundation.
|
|
||||||
|
|
||||||
14. If you wish to incorporate parts of the Library into other free
|
|
||||||
programs whose distribution conditions are incompatible with these,
|
|
||||||
write to the author to ask for permission. For software which is
|
|
||||||
copyrighted by the Free Software Foundation, write to the Free
|
|
||||||
Software Foundation; we sometimes make exceptions for this. Our
|
|
||||||
decision will be guided by the two goals of preserving the free status
|
|
||||||
of all derivatives of our free software and of promoting the sharing
|
|
||||||
and reuse of software generally.
|
|
||||||
|
|
||||||
NO WARRANTY
|
|
||||||
|
|
||||||
15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
|
|
||||||
WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
|
|
||||||
EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
|
|
||||||
OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
|
|
||||||
KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
|
|
||||||
IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
|
|
||||||
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
|
|
||||||
LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
|
|
||||||
THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
|
|
||||||
|
|
||||||
16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
|
|
||||||
WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
|
|
||||||
AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
|
|
||||||
FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
|
|
||||||
CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
|
|
||||||
LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
|
|
||||||
RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
|
|
||||||
FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
|
|
||||||
SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
|
|
||||||
DAMAGES.
|
|
||||||
|
|
||||||
END OF TERMS AND CONDITIONS
|
|
||||||
|
|
||||||
How to Apply These Terms to Your New Libraries
|
|
||||||
|
|
||||||
If you develop a new library, and you want it to be of the greatest
|
|
||||||
possible use to the public, we recommend making it free software that
|
|
||||||
everyone can redistribute and change. You can do so by permitting
|
|
||||||
redistribution under these terms (or, alternatively, under the terms of the
|
|
||||||
ordinary General Public License).
|
|
||||||
|
|
||||||
To apply these terms, attach the following notices to the library. It is
|
|
||||||
safest to attach them to the start of each source file to most effectively
|
|
||||||
convey the exclusion of warranty; and each file should have at least the
|
|
||||||
"copyright" line and a pointer to where the full notice is found.
|
|
||||||
|
|
||||||
<one line to give the library's name and a brief idea of what it does.>
|
|
||||||
Copyright (C) <year> <name of author>
|
|
||||||
|
|
||||||
This library is free software; you can redistribute it and/or
|
|
||||||
modify it under the terms of the GNU Lesser General Public
|
|
||||||
License as published by the Free Software Foundation; either
|
|
||||||
version 2.1 of the License, or (at your option) any later version.
|
|
||||||
|
|

* On Linux and other Unix flavors OpenCV uses default or user-built ffmpeg/libav libraries.
|
The build script is to be fixed.
|
||||||
If user builds ffmpeg/libav from source and wants OpenCV to stay BSD library, not GPL/LGPL,
|
Right now it assumes that 32-bit MinGW is in the system path and
|
||||||
he/she should use --enabled-shared configure flag and make sure that no GPL components are
|
64-bit mingw is installed to c:\Apps\MinGW64.
|
||||||
enabled (some notable examples are x264 (H264 encoder) and libac3 (Dolby AC3 audio codec)).
|
|
||||||
See https://www.ffmpeg.org/legal.html for details.
|
|
||||||
|
|
||||||
If you want to play very safe and do not want to use FFMPEG at all, regardless of whether it's installed on
|
It is important that gcc is used, not g++!
|
||||||
your system or not, configure and build OpenCV using CMake with WITH_FFMPEG=OFF flag. OpenCV will then use
|
Otherwise the produced DLL will likely be dependent on libgcc_s_dw2-1.dll or similar DLL.
|
||||||
AVFoundation (OSX), GStreamer (Linux) or other available backends supported by opencv_videoio module.
|
While we want to make the DLLs with minimum dependencies: Win32 libraries + msvcrt.dll.
|
||||||
|
|
||||||
There is also our self-contained motion jpeg codec, which you can use without any worries.
|
ffopencv.c is really a C++ source, hence -x c++ is used.
|
||||||
It handles CV_FOURCC('M', 'J', 'P', 'G') streams within an AVI container (".avi").
|
|
||||||
|
|
||||||
* On Windows OpenCV uses pre-built ffmpeg binaries, built with proper flags (without GPL components) and
|
How to update opencv_ffmpeg.dll and opencv_ffmpeg_64.dll when a new version of FFMPEG is release?
|
||||||
wrapped with simple, stable OpenCV-compatible API.
|
|
||||||
The binaries are opencv_videoio_ffmpeg.dll (version for 32-bit Windows) and
|
|
||||||
opencv_videoio_ffmpeg_64.dll (version for 64-bit Windows).
|
|
||||||
|
|
||||||
The pre-built opencv_videoio_ffmpeg*.dll is:
|
1. Install 32-bit MinGW + MSYS from
|
||||||
* LGPL library, not BSD libraries.
|
http://sourceforge.net/projects/mingw/files/Automated%20MinGW%20Installer/mingw-get-inst/
|
||||||
* Loaded at runtime by opencv_videoio module.
|
Let's assume, it's installed in C:\MSYS32.
|
||||||
If it succeeds, ffmpeg can be used to decode/encode videos;
|
2. Install 64-bit MinGW. http://mingw-w64.sourceforge.net/
|
||||||
otherwise, other API is used.
|
Let's assume, it's installed in C:\MSYS64
|
||||||
|
3. Copy C:\MSYS32\msys to C:\MSYS64\msys. Edit C:\MSYS64\msys\etc\fstab, change C:\MSYS32 to C:\MSYS64.
|
||||||
|
|
||||||
FFMPEG build includes support for H264 encoder based on the OpenH264 library.
|
4. Now you have working MSYS32 and MSYS64 environments.
|
||||||
OpenH264 Video Codec provided by Cisco Systems, Inc.
|
Launch, one by one, C:\MSYS32\msys\msys.bat and C:\MSYS64\msys\msys.bat to create your home directories.
|
||||||
See https://github.com/cisco/openh264/releases for details and OpenH264 license.
|
|
||||||
OpenH264 library should be installed separatelly. Downloaded binary file can be placed into global system path
|
|
||||||
(System32 or SysWOW64) or near application binaries (check documentation of "LoadLibrary" Win32 function from MSDN).
|
|
||||||
Or you can specify location of binary file via OPENH264_LIBRARY environment variable.
|
|
||||||
|
|
||||||
If LGPL/GPL software can not be supplied with your OpenCV-based product, simply exclude
|
4. Download ffmpeg-x.y.z.tar.gz (where x.y.z denotes the actual ffmpeg version).
|
||||||
opencv_videoio_ffmpeg*.dll from your distribution; OpenCV will stay fully functional except for the ability to
|
Copy it to C:\MSYS{32|64}\msys\home\<loginname> directory.
|
||||||
decode/encode videos using FFMPEG (though, it may still be able to do that using other API,
|
|
||||||
such as Video for Windows, Windows Media Foundation or our self-contained motion jpeg codec).
|
|
||||||
|
|
||||||
See license.txt for the FFMPEG copyright notice and the licensing terms.
|
5. To build 32-bit ffmpeg libraries, run C:\MSYS32\msys\msys.bat and type the following commands:
|
||||||
|
|
||||||
|
5.1. tar -xzf ffmpeg-x.y.z.tar.gz
|
||||||
|
5.2. mkdir build
|
||||||
|
5.3. cd build
|
||||||
|
5.4. ../ffmpeg-x.y.z/configure --enable-w32threads
|
||||||
|
5.5. make
|
||||||
|
5.6. make install
|
||||||
|
5.7. cd /local/lib
|
||||||
|
5.8. strip -g *.a
|
||||||
|
|
||||||
|
6. Then repeat the same for 64-bit case. The output libs: libavcodec.a etc. need to be renamed to libavcodec64.a etc.
|
||||||
|
|
||||||
|
7. Then, copy all those libs to <opencv>\3rdparty\lib\, copy the headers to <opencv>\3rdparty\include\ffmpeg_.
|
||||||
|
|
||||||
|
8. Then, go to <opencv>\3rdparty\ffmpeg, edit make.bat
|
||||||
|
(change paths to the actual paths to your msys32 and msys64 distributions) and then run make.bat

|
||||||
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
|
|
||||||
implied, including, without limitation, any warranties or conditions
|
|
||||||
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
|
|
||||||
PARTICULAR PURPOSE. You are solely responsible for determining the
|
|
||||||
appropriateness of using or redistributing the Work and assume any
|
|
||||||
risks associated with Your exercise of permissions under this License.
|
|
||||||
|
|
||||||
8. Limitation of Liability. In no event and under no legal theory,
|
|
||||||
whether in tort (including negligence), contract, or otherwise,
|
|
||||||
unless required by applicable law (such as deliberate and grossly
|
|
||||||
negligent acts) or agreed to in writing, shall any Contributor be
|
|
||||||
liable to You for damages, including any direct, indirect, special,
|
|
||||||
incidental, or consequential damages of any character arising as a
|
|
||||||
result of this License or out of the use or inability to use the
|
|
||||||
Work (including but not limited to damages for loss of goodwill,
|
|
||||||
work stoppage, computer failure or malfunction, or any and all
|
|
||||||
other commercial damages or losses), even if such Contributor
|
|
||||||
has been advised of the possibility of such damages.
|
|
||||||
|
|
||||||
9. Accepting Warranty or Additional Liability. While redistributing
|
|
||||||
the Work or Derivative Works thereof, You may choose to offer,
|
|
||||||
and charge a fee for, acceptance of support, warranty, indemnity,
|
|
||||||
or other liability obligations and/or rights consistent with this
|
|
||||||
License. However, in accepting such obligations, You may act only
|
|
||||||
on Your own behalf and on Your sole responsibility, not on behalf
|
|
||||||
of any other Contributor, and only if You agree to indemnify,
|
|
||||||
defend, and hold each Contributor harmless for any liability
|
|
||||||
incurred by, or claims asserted against, such Contributor by reason
|
|
||||||
of your accepting any such warranty or additional liability.

|

HarfBuzz started as a text shaping engine but has grown into a
|
|
||||||
full font platform — the `ffmpeg` of text shaping. It primarily
|
|
||||||
supports [OpenType][1], but also [Apple Advanced Typography][2].
|
|
||||||
|
|
||||||
HarfBuzz shapes the majority of text on modern screens.
|
|
||||||
|
|
||||||
HarfBuzz is optimized for robustness, correctness, and performance
|
|
||||||
— in that order. Achieve all.
|
|
||||||
|
|
||||||
**[Try it live at harfbuzz-world.cc](https://harfbuzz-world.cc/)** — an interactive playground for shaping, subsetting, rasterization, vector output, and GPU rendering, all running in your browser.
|
|
||||||
|
|
||||||
Here is a quick map of its components:
|
|
||||||
|
|
||||||
### Core libraries
|
|
||||||
|
|
||||||
| Library | Description |
|
|
||||||
|---------|-------------|
|
|
||||||
| **libharfbuzz** | Text shaping, draw API, paint API. Highly configurable (see [CONFIG.md](CONFIG.md)). Optional integration backends compiled in: hb-ft (FreeType), hb-coretext (macOS), hb-uniscribe (Windows), hb-directwrite (Windows), hb-gdi (Windows), hb-glib, hb-graphite2. |
|
|
||||||
| **libharfbuzz-subset** | Font subsetting and variable-font instancing. |
|
|
||||||
|
|
||||||
### Auxiliary libraries
|
|
||||||
|
|
||||||
| Library | Description |
|
|
||||||
|---------|-------------|
|
|
||||||
| **libharfbuzz-icu** | ICU Unicode integration. |
|
|
||||||
| **libharfbuzz-cairo** | Cairo rendering integration. |
|
|
||||||
| **libharfbuzz-gobject** | GObject/GI bindings. |
|
|
||||||
|
|
||||||
### Experimental libraries
|
|
||||||
|
|
||||||
| Library | Description |
|
|
||||||
|---------|-------------|
|
|
||||||
| **libharfbuzz-raster** | Glyph rasterization to bitmaps, including color fonts. Uses hb-draw and hb-paint. |
|
|
||||||
| **libharfbuzz-vector** | Glyph output to vector formats (currently SVG), including color fonts. Uses hb-draw and hb-paint. |
|
|
||||||
| **libharfbuzz-gpu** | Encodes glyph outlines for GPU rasterization (Slug algorithm). Provides shader sources in GLSL, WGSL, MSL, and HLSL. [Live demo.](https://harfbuzz.github.io/hb-gpu-demo/) |
|
|
||||||
|
|
||||||
Notable missing feature: font hinting (including autohinting)
|
|
||||||
is not implemented. For hinted rasterization, use FreeType or
|
|
||||||
Skrifa.
|
|
||||||
|
|
||||||
For simplified builds, amalgamated sources are available:
|
|
||||||
`harfbuzz.cc` (just libharfbuzz), `harfbuzz-subset.cc` (just
|
|
||||||
libharfbuzz-subset), or `harfbuzz-world.cc` (everything, driven
|
|
||||||
by a custom `hb-features.h`). For a live in-browser playground
|
|
||||||
plus a worked example of the world.cc single-file build, see
|
|
||||||
[harfbuzz-world.cc][26].
|
|
||||||
|
|
||||||
### Command-line tools
|
|
||||||
|
|
||||||
| Tool | Description |
|
|
||||||
|------|-------------|
|
|
||||||
| **hb-shape** | Shape text and display glyph output. |
|
|
||||||
| **hb-view** | Render shaped text to an image. |
|
|
||||||
| **hb-subset** | Subset and optimize fonts. |
|
|
||||||
| **hb-info** | Display font metadata. |
|
|
||||||
| **hb-raster** | Render glyphs to bitmap images. |
|
|
||||||
| **hb-vector** | Render glyphs to vector formats (SVG). |
|
|
||||||
| **hb-gpu** | Interactive GPU text rendering. |
|
|
||||||
|
|
||||||
The canonical source tree and bug trackers are available on [github][4].
|
|
||||||
Both development and user support discussion around HarfBuzz happen on
|
|
||||||
[github][4] as well.
|
|
||||||
|
|
||||||
For license information, see [COPYING](COPYING).
|
|
||||||
|
|
||||||
## API stability
|
|
||||||
|
|
||||||
The API that comes with `hb.h` will not change incompatibly. Other, peripheral,
|
|
||||||
headers are more likely to go through minor modifications, but again, we do our
|
|
||||||
best to never change API in an incompatible way. We will never break the ABI.
|
|
||||||
|
|
||||||
The API and ABI are stable even across major version number jumps. In fact,
|
|
||||||
current HarfBuzz is API/ABI compatible all the way back to the 0.9.x series.
|
|
||||||
If one day we need to break the API/ABI, that would be called a new library.
|
|
||||||
|
|
||||||
As such, we bump the major version number only when we add major new features,
|
|
||||||
the minor version when there is new API, and the micro version when there
|
|
||||||
are bug fixes.
|
|
||||||

## Name
|
|
||||||
|
|
||||||
HarfBuzz /hærfˈbɒːz/
|
|
||||||
|
|
||||||
From Persian حرف (*Harf*: letter) and باز (*Buzz*: open).
|
|
||||||
Transliteration of the Persian calque for *OpenType*.
|
|
||||||
|
|
||||||
As a noun: *The* Open Source *text shaping* engine.
|
|
||||||
|
|
||||||
As an adjective: Insincerely talkative; glib. A nod to the
|
|
||||||
GNOME project where HarfBuzz originates from.
|
|
||||||
|
|
||||||
The logo shows حرفباز in the IranNastaliq font, on a Damascus
|
|
||||||
steel background.
|
|
||||||
|
|
||||||
> Background: Originally there was this font format called TrueType. People and
|
|
||||||
> companies started calling their type engines all things ending in Type:
|
|
||||||
> FreeType, CoolType, ClearType, etc. And then came OpenType, which is the
|
|
||||||
> successor of TrueType. So, for my OpenType implementation, I decided to stick
|
|
||||||
> with the concept but use the Persian translation. Which is fitting given that
|
|
||||||
> Persian is written in the Arabic script, and OpenType is an extension of
|
|
||||||
> TrueType that adds support for complex script rendering, and HarfBuzz is an
|
|
||||||
> implementation of OpenType text shaping.
|
|
||||||

hb_extract.py -- copy the minimal subset of HarfBuzz sources used by OpenCV.
|
|
||||||
|
|
||||||
OpenCV vendors HarfBuzz as a normal static library: every .cc is a separate
|
|
||||||
translation unit (no unity / amalgamation build). This script reproduces the
|
|
||||||
exact src/ tree that OpenCV ships, from a pristine HarfBuzz checkout.
|
|
||||||
|
|
||||||
It does three things beyond a naive copy, all to keep the vendored tree small
|
|
||||||
and buildable with OpenCV's configuration (HB_TINY + HB_HAS_RASTER, see
|
|
||||||
CMakeLists.txt):
|
|
||||||
|
|
||||||
1. Copies the translation units that upstream `harfbuzz-world.cc` would
|
|
||||||
compile for the requested HB_HAS_* sections -- EXCEPT the ones that build
|
|
||||||
to an empty object under our config (see EMPTY_TUS). It never emits
|
|
||||||
`harfbuzz-world.cc` itself (we compile each .cc directly), and never
|
|
||||||
copies non-TU .cc files found under src/OT|graph (only real TUs from the
|
|
||||||
parsed world.cc lists are copied), so CMake's file(GLOB_RECURSE src/*.cc)
|
|
||||||
picks up exactly the right set.
|
|
||||||
|
|
||||||
2. Prunes headers down to the set actually reachable by #include from the
|
|
||||||
copied TUs (+ the public headers OpenCV includes). This automatically
|
|
||||||
drops the large amount of HarfBuzz src/ that we never compile -- GPU and
|
|
||||||
WASM backends, the subset/repacker graph, platform backends (CoreText/
|
|
||||||
DirectWrite/GDI/Uniscribe/Graphite2/GObject/Cairo), the vector-paint
|
|
||||||
backend, and headers used only by the skipped empty TUs -- without a
|
|
||||||
hardcoded blocklist.
|
|
||||||
|
|
||||||
3. Generates `hb-opencv-config.hh`, the config-override header CMakeLists.txt
|
|
||||||
points HB_CONFIG_OVERRIDE_H at. It re-enables thread-safety (HB_NO_MT) and
|
|
||||||
variable fonts (HB_NO_VAR) that HB_TINY would otherwise switch off. (It
|
|
||||||
does NOT generate upstream's hb-features.h: nothing we compile includes
|
|
||||||
it.)
|
|
||||||
|
|
||||||
Usage (to refresh this very directory, just point it at a harfbuzz checkout):
|
|
||||||
python hb_extract.py path/to/harfbuzz
|
|
||||||
|
|
||||||
The defaults already produce the OpenCV subset: output '.', features
|
|
||||||
HB_HAS_RASTER, and it also copies README.md + COPYING. Override only if needed:
|
|
||||||
-o DIR output root (default '.')
|
|
||||||
-f FLAGS comma-separated HB_HAS_* (default HB_HAS_RASTER)
|
|
||||||
-a FILES extra files (default README.md,COPYING)
|
|
||||||
--list-flags print available HB_HAS_* flags and exit
|
|
||||||
|
|
||||||
-a paths are relative to the harfbuzz repo root (parent of src/):
|
|
||||||
-a README.md -> copied to <out>/README.md
|
|
||||||
-a COPYING -> copied to <out>/COPYING
|
|
||||||
-a src/hb-raster.h -> copied to <out>/src/hb-raster.h

* HarfBuzz is built with HB_TINY (see 3rdparty/harfbuzz/CMakeLists.txt) for the
|
|
||||||
* smallest possible footprint. HB_TINY pulls in HB_LEAN + HB_MINI, which would
|
|
||||||
* disable two features that OpenCV's text engine relies on. We restore them
|
|
||||||
* here.
|
|
||||||
*
|
|
||||||
* This file is included by hb-config.hh via HB_CONFIG_OVERRIDE_H, i.e. AFTER
|
|
||||||
* HB_TINY/HB_LEAN/HB_MINI have expanded their macros (so the #undef below takes
|
|
||||||
* effect) but BEFORE the "closure of options" derives dependent macros (e.g.
|
|
||||||
* HB_NO_VAR_COMPOSITES from HB_NO_VAR). That ordering is what makes a plain
|
|
||||||
* #undef sufficient.
|
|
||||||
*
|
|
||||||
* HB_NO_MT - keep thread-safety. hb_font_t instances live inside cv::FontFace
|
|
||||||
* objects, NOT in the thread_local FontRenderEngine, so a single
|
|
||||||
* FontFace (and its hb_font_t) can be shared across threads; its
|
|
||||||
* reference counting must stay atomic.
|
|
||||||
*
|
|
||||||
* HB_NO_VAR - keep variable-font support: the 'wght' axis used for synthetic
|
|
||||||
* weights and named-instance/axis queries (hb_font_set_variations,
|
|
||||||
* hb_ot_var_*). Variable fonts are a primary reason OpenCV adopted
|
|
||||||
* HarfBuzz, so this must remain enabled.
