OK not strictly .NET but thought someone might know.

I have an image which will be my sprite. When I draw it to screen I can see pixels which are in the transparecy area. I open the image in Paint, zoom in very large and have tried, erasing, changing to black, changing to white etc. But each time I save changes there are always a number of pixels which get changed back?

I have the file as jpeg. I use this as the image is crisper than gif.
 
jpeg compression works on smooth tones and shades, the saving is probably introducing these artifacts as part of the compression process.
Better using GIF or PNG in this case.
 
yeah, you are right thanks. Shame tho as the jpeg image looks much better.
