    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
    Code:
    Temp = Me.GetIQ()
'Error 9: Overflow

    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
