What steps will reproduce the problem?
IplImage frame, image;
CvRect face = CvRect(...);
cvSetImageROI(frame, face);
image = cvCreateImage(cvGetSize(frame), frame.depth(), frame.nChannels());
cvCopy(frame, image);
cvResetImageROI(frame);
What is the expected output? What do you see instead?
It is expected that image now contains basically a cropped image, with same
colour mode, etc.
What is produced is the correctly sized image, but with a different colour mode.
What version of the product are you using? On what operating system?
java-0.1-bin.zip
OpenCV 2.4.0
Mac OSX Lion
Please provide any additional information below.
While debugging I grabbed the pixel of the top left of the CvRect, to examine
it, and received the following:
frame BGRA = {99,78,83,255}
image BGRA = {78,83,0,255}
these results were consistent no matter how long I ran it for. It looks like
the G channel has become the B channel, the R has become the G, and the B has
disappeared, making the new R 0.
