C++, Negative RGB values of pixels using OpenCV

Question

I\'m using OpenCV to iterate through an image and find the colour of each pixel, here\'s some of the code I\'m using:

IplImage* img = cvLoadImage(\"c:\\\\tes         


        

Answer 1

I've never used OpenCV, but I would imagine that cvCreateImage doesn't initialise the contents of the image, and certainly not to anything meaningful.
