Hi Koduri,

for the project I'm working on I needed something similar.
Using the C++ API of OpenCV I found the following code to be working:


Code:

osgImg->readPixels( 0, 0, width, height, GL_BGR, GL_UNSIGNED_BYTE );
cv::Mat cvImg(osgImg->t(), osgImg->s(), CV_8UC3); 
cvImg.data = (uchar*)osgImg->data();

// Flipping because of different origins
cv::flip(cvImg, cvImg, 0);





Cheers,
Dakota
