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
