image bg trancparency

[amanteragazzo]

I need to make the background of an image transparent. I tried to use the api, but it ate way too much memory. Is there any other way?

go to www.ur.co.nz and read the bitblt tutorial, basically what you do is blit a mask first, to make everything that is supposed to be visible black on the destination dc and than you blit your picture to every black pixel.
works real easy just take a look.
