    if you could say in wich mode the painting program runs (resolution etc and with what method u color the pixel) then it would be much easier to answer your question

    if you are able to use various resolutions, you can probably just lower the resolution (therefore making the images look bigger).

    1) Pick a magnification value.
    2) Pick a size for the "display area". This should ideally squares or powers 2, as should the magnification value.
    3) Multiply each pixel by the magnification.
    Code:
    [][]
    [][]    2x2 magnification
    
    [][][]
    [][][]
    [][][] 3x3 magnification
    
    [][][][]
    [][][][]
    [][][][]
    [][][][] 4x4 magnification
    
    And so on.
    Basicly, you just duplicate the exact same pixel color for more pixels. It should be a fairly trivial exercize if you already know how to work with graphics.

    Hope is the first step on the road to disappointment.
