This folder contains libraries and headers of a few very popular still image codecs
|
|
|
|
|
used by imgcodecs module.
|
|
|
|
|
The libraries and headers are preferably to build Win32 and Win64 versions of OpenCV.
|
|
|
|
|
On UNIX systems all the libraries are automatically detected by configure script.
|
|
|
|
|
In order to use these versions of libraries instead of system ones on UNIX systems you
|
|
|
|
|
should use BUILD_<library_name> CMake flags (for example, BUILD_PNG for the libpng library).
