Error for rectangular images

[mihaelkovach]

For rectangular images I always see this error:

Error in file "c:/2.PNG" processing: ........\opencv\modules\core\src\matrix.cpp:323: error: (-215) 0 <= roi.x && 0 <= roi.width && roi.x + roi.width <= m.cols && 0 <= roi.y && 0 <= roi.height && roi.y + roi.height <= m.rows in function cv::Mat::Mat

Example of the image:
