imwrite (filename, image ) → retval ¶ C: int cvSaveImage (const char* filename, const CvArr* image ) ¶ Python: cv. C++: bool imwrite (const string& filename, InputArray image, const vector& params=vector() ) ¶ Python: cv2. Currently, the following file formats are supported: If the image cannot be read (because of missing file, improper permissions, unsupported or invalid format), the function returns an empty matrix ( Mat::data=NULL ). The function imread loads an image from the specified file and returns it. For example, a 4-channel RGBA image is loaded as RGB if. Note that in the current implementation the alpha channel, if any, is stripped from the output image. LoadImageM (filename, flags=CV_LOAD_IMAGE_COLOR ) → None ¶ Parameters:įlags specifying the color type of a loaded image: LoadImage (filename, flags=CV_LOAD_IMAGE_COLOR ) → None ¶ Python: cv. imread (filename ) → retval ¶ C: IplImage* cvLoadImage (const char* filename, int flags=CV_LOAD_IMAGE_COLOR ) ¶ C: CvMat* cvLoadImageM (const char* filename, int flags=CV_LOAD_IMAGE_COLOR ) ¶ Python: cv. C++: Mat imread (const string& filename, int flags=1 ) ¶ Python: cv2.
