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)
