MaskBlt (how to draw masked image?)
Posted on 1998-10-16
::MaskBlt ( myHDC , 0 ,0 ,width ,height ,myhMemDC ,x ,y ,mymask ,0 ,0 ,raster_operation_code );
myHDC is a HDC of a window
myhMemDC is a HDC with a selected RGB bitmap
my mask is a HBITMAP of a monochrome bitmap.
What do I have to put in raster op. code to draw only in the part where my mask is white?
I tried with all methods listed in BitBlt but nothing.
And I tried with MAKEROP4 macro, but I dont understand what arguments to pass.
Help me peopple please.
