Jan Polák	dea0815199	Small imencode documentation improvement It was previously not clear that the extension should include the period, [and I am not the only person that encountered this problem](https://stackoverflow.com/questions/4254460/opencv-could-not-find-encoder-for-the-specified-extension). I assume that this is true for all supported extensions, but I haven't checked the source.	3 years ago

nickjackolson	79d4e865fe	Add warning message to imread() Add a warning message using CV_LOG__WARNING(). This way api behaviour is preserved. Outputs are the same but user gets an extra warning in case fopen() fails to access image file for some reason. This would help new users and also debugging complex apps which use imread() Signed-off-by: nickjackolson <metedurlu@gmail.com>	3 years ago

Zhuo Zhang	84a290097b	fix link order: put zlib after png/tiff/openexr Previous link dependency: imgcodecs --> zlib --> libpng this can generate imgcodecs shared lib, until Visual Studio integrated with vcpkg, which will additionally specify LIBPATH, pointing to vcpkg installed zlib (if any), which links the wrong zlib. Fixed link dependency: imgcodecs --> libpng --> zlib in this fixed case, symbols in zlib referenced in libpng will be found in the build-from-source static zlib, instead of the vcpkg one. related discussion: - https://github.com/microsoft/vcpkg/issues/16165 - https://github.com/opencv/opencv/issues/17051 - https://github.com/opencv/opencv/issues/10576 MSVC linking order reference pages: - https://docs.microsoft.com/en-us/cpp/build/reference/link-input-files?view=msvc-160 for link order - https://docs.microsoft.com/en-us/cpp/build/reference/linking?view=msvc-160 LIB environment variable, for library file searching - https://docs.microsoft.com/en-us/cpp/build/reference/libpath-additional-libpath?view=msvc-160 LIBPATH option, for library file searching	4 years ago
