Replacing colors in images?

| Hi, Does anyone know what would be the fastest way to replace colorA with one colorB, and colorC with colorD in an image? I could loop trough all the pixels and replace, but would there be a more efficient way? Possibly by masking colorA and putting the image over an image with colorB, and doing the same for colorC and colorD? Also, is there a built-in way to copy an image on top of another, but using simple filters, like you can do with textures using TextureBlend? Thanks! |

| Hmmm, should have looked in the code archive prior to posting, these links seem to be what I'm looking for : http://www.blitzbasic.com/codearcs/codearcs.php?code=883 (replace color) http://www.blitzbasic.com/codearcs/codearcs.php?code=1371 (5 overlay effects) I'll try them out tomorrow and see if they're what I need. |
