Supported QImage formats and cv::Mat types are:
- QImage::Format_Indexed8 <==> CV_8UC1
- QImage::Format_Alpha8 <==> CV_8UC1
- QImage::Format_Grayscale8 <==> CV_8UC1
- QImage::Format_RGB888 <==> CV_8UC3 (R G B)
- QImage::Format_RGB32 <==> CV_8UC4 (A R G B or B G R A)
- QImage::Format_ARGB32 <==> CV_8UC4 (A R G B or B G R A)
- QImage::Format_ARGB32_Premultiplied <==> CV_8UC4 (A R G B or B G R A)
- QImage::Format_RGBX8888 <==> CV_8UC4 (R G B A)
- QImage::Format_RGBA8888 <==> CV_8UC4 (R G B A)
- QImage::Format_RGBA8888_Premultiplied <==> CV_8UC4 (R G B A)
For QImage::Format_RGB32 ,QImage::Format_ARGB32 and QImage::Format_ARGB32_Premultiplied, the color channel order of cv::Mat will be (B G R A) in little endian system or (A R G B) in big endian system.
