    Hiyas,

    Here's what I'm doing. I open a picture up into a hidden picturebox, called TileSource. The image is 640 * 480 pixels. It's 20 tiles across and 15 down (32x32 pixel tiles).

    I want to shrink the entire image 1/4 the size, so the 32x32 pixel tiles become 24x24. Which is the best method - StretchBlt or PaintPicture, and how would I do this? (I only really know BitBlt)

    Hi there,

    I'd just shrink the image in a graphics program.
    Image manipulation on the fly is quite processor intensive and a nono (imho) for games.

    Actually it's a game editor, so speed doesn't matter. =) (and shrinking before load is out of the question too)
