    background color

    i am looking for a program that will report to me the background color of any pixel on the screen, so like if i was hovering my mouse over a picture it would tell me the color of the pixel that the mouse was currently sitting over...

    anyone know of such a program? i have seen one before, but dont know where to get it

    whee, you need the code for it?

    Check out my runescape miner program in my portfolio:
    direct link:

    the code is in editmain.cpp in the source code

    here's the code so you don't have to search for it
        // Grab the display's rendering context
        HDC hDC;
        hDC = CreateDC("DISPLAY",0,0,0);
        // Cursor position, wheee
        POINT Cursor;
        // It's stored as RGB or BGR or something, slipping my mind right now
        COLORREF color;
        // Clean up, yaay!
        // Outputting junk for the win32 box...
        char Text[128];
        SetWindowText(GetDlgItem(hwnd,IDC_PIXELCOLORHEX), Text);
        SetWindowText(GetDlgItem(hwnd,IDC_PIXELCOLORB), Text);
        SetWindowText(GetDlgItem(hwnd,IDC_PIXELCOLORG), Text);
        SetWindowText(GetDlgItem(hwnd,IDC_PIXELCOLORR), Text);
        SetWindowText(GetDlgItem(hwnd,IDC_PIXELX), Text);
        SetWindowText(GetDlgItem(hwnd,IDC_PIXELY), Text);
    Have fun dissecting that, it's not too tough, really all you need is the first block of code

    yah, it's stored as BGR in the hex value

    Naturally I didn't feel inspired enough to read all the links for you, since I already slaved away for long hours under a blistering sun pressing the search button after typing four whole words! - Quzah
