| Try SetMaskColor. |

| I actually don't bother with the mask colour any more. I make use of art packages that can save images with alpha/transparancy and set the blend mode to ALPHABLEND with SetBlend before drawing them in BlitzMax. No need to worry about mask colours and you get lovely anti-aliased edges (provided that you drew to a transparent background layer and used anti-aliased drawing tools, of course). |
| ||
| I don't bother either. As long as you don't want to change the maskcolour or are using somebody else's images. I checked to see if I'd forgotten anything. After making a complete charlie out of myself I didn't get many responses to say "Don't do that"... CharlieMaker |

| @JazzieB thats the same way id do it so far, but i had much problems with anti-aliased images :( ... Could you please tell me wich tool you use for this ? |

| I use Paint Shop Pro 9. When drawing your images make sure that when you create the image that the background colour is transparent. I then just save as PNG. In BlitzMax, you load the images as normal (the default flags are fine) and when displaying them, make sure that alphablend is enabled...
Global img:TImage=LoadImage("image.png")
SetBlend ALPHABLEND
DrawImage img,300,200
Flip
I generally set ALPHABLEND once just before the main loop and leave it. |
