What is the diffrence?

Hi, Guys!

I have a little question:
What is the diffrence between vbSrcInvert and vbSrcPaint?

Thank you,
Arie. (mag.up.co.il)

vbSrcPaint uses an Or operator. The result is a weird combination of the two images that looks a lot like Additive Blend (darker = more transparent).

vbSrcInvert uses a Xor operator. It seems to work like vbSrcPaint except that it inverts the image before blting it.

Hope that clears everything :)

Ok...
What should I use? What's best?

If you just want to draw an image, use vbSrcCopy. If you want transparent areas, that's a little more complex, just reply here again. If you want to use a cheap special effect :) use vbSrcPaint ;)
