/*! Various border types, image boundaries are denoted with the `|` character in the table below, when describing each method.
The following examples show the result of the @ref copyMakeBorder call according to different methods.
Input image is `6x4` (width x height) size and the @ref copyMakeBorder function is used with a border size of 2 pixels
in each direction, giving a resulting image of `10x8` resolution.
