    anti-aliasing shapes

    My question is how to create anti-aliased shapes using a byte-array as a buffer.

    I have the byte array structure.

    The shapes would include a rounded-rectangle, and a triangle.

    What about shadowing them?

    Hope it helps...

    Bummer...I searched through a whole bunch of different VB sites individually, and used a couple of search engines on "Anti-Alising" and that was the only thing I found.

    Sorry...

    BTW: I don't have a very big background with graphics or gaming so forgive me if this is a stupid question, but what is "anti-aliased shape"?

    For anti-aliasing you need an algorithm that takes a bunch of pixels, analyzes the pixel colors there and computes weighted averages to fill the pixels with. Assumin a 2x2 anti-aliasing of a 16 grays image, given the block

    16 0
    0 16

    the algorithm should convert this to
    10 6
    6 10

    which would be a weighted average.
    The larger the block the better the results, but the slower the algorithm.
    All the buzzt
