Description

See attached Screen-shot for example.

In the provided example all 3 values R,G,B are showing in the zoomed image. https://code.ros.org/trac/opencv/attachment/ticket/520/main2_screenshot_14.08.2010.png

In the Screen-shot I have attached only the Grey value is shown.

Note that I am using pure c++ in my code (only MAT used, no IplImage) and I think this is the problem here.

In the status bar at the bottom until recently I only saw "Grey: value" until the last few builds where you switched to use MAT rather than IplImage and as you can see from the attached screenshot the R,G,B values are shown correctly on the status bar at the bottom.
