I have got an error trying to scan image content and process it pixel by pixel. I decided to check MyImage.data. Microsoft Debugger perfectly shows all the object members, but the content of .data is all (unsigned char)255. Meanwhile the image normally shows using
    imshow(window_name, MyImage);
I use opencv-2.4.13.2-vc14.exe and read image from file:
    Mat MyImage;
    MyImage = imread("Circle.bmp", IMREAD_GRAYSCALE);
What's wrong?

I can watch it using imshow(). I need to inspect content of the matrix. MyImage.data. Even better - each element MyImage.data(i,j).

OK. "It also displays the pixel coordinate and value at the current mouse position."
