Hi,
Does cv_bridge support converting ROI image to ROS msg?
I'm trying to publish ROI cropped image as followings, however the
hoge.ppm and published image message are differ.
hoge.ppm start from (width/2 height/2) of the original image but
published image starts from (0 0).Both image size are width/2 and height/2.
IplImage *frame = ....;
int width = frame->width, height = frame->height;
cvSetImageROI(frame, cvRect(width/2, height/2, width/2, height/2));
cvSaveImage("hoge.ppm", frame);
pub_narrow_.publish(bridge.cvToImgMsg(frame, "bgr8"));
