使用QImage与OpenCV之间互相转换时,一般情况下QImage支持的格式是RGB888,对应的OpenCV中的Mat格式则为CV_8UC3,即8位无符号的三通道数据;但是,在某些特殊情况下,QImage也会支持ARGB32、RGB32、RGB16、RGB555、RGB444等格式,而对应OpenCV中的Mat格式则为:ARGB:CV_8UC4,RGB32/RGB16:CV_8UC2,RGB555/RGB444:CV_...

). On the Internet there is some explanation of pointer ownership in cv::Mat and I thought it would be released after the last reference to it is release which should not be the case since "out" is a reference. Btw. another way to convert an SVG into a cv::Mat is always welcome....
