Wow, it looks so amazing and easy! :) So, may be I move some my number-crunchers to C-DLLs. ;) Thanks!

I do not need to save the image to a file, I want to analyze it programmatically. Something similar to this:


Code Select
typedef struct point {
    int x;
    int y;
} Point;

Point points[] = {
    { 1, 10 },
    { 20, 3 },
    { 640, 480 },
    { 0, 0 }
};

COLORREF colors[4];

HDC h = GetDC(NULL); // handle of desktop
for( int i = 0; i < 4; i++ ) {
    colors[i] = GetPixel(h, points[i].x, points[i].y);
}
ReleaseDC(h);
