Use SRCAND as your OP code.

Retval = BitBlt(Form1.hDC, 0, 0, 100, 100, MyPic.hDC, 0, 0, SRCAND)

You must change all picture backgrounds to black and all signature (mask) backgrounds to white. All signature (mask) files should have black where it should be opaque. EG:

rc=bitblt(picdest.hdc,0,0,100,100,picmask.hdc,0,0,srcand)

rc=bitblt(picdest.hdc,0,0,100,100,picspr.hdc,0,0,srcpaint)

I don't know what do you mean,,,please try to explain it to me in easy english,,,,thanks

First you must put down a mask, then you must put down your picture. A mask is like a silouette. The image is black and the background is white.

Use his code (listed above) to first put on the mask and then your picture.
