I'm still struggling on understanding how to modify the blend an image
over an OffScreenWindow. To make like easier, since the background is
black, I reckon the way could be after I draw the image on the OffScreen
Window, to make the OffScreenWindow more or less darker. Easy, isn't i? :D
Well, of course not for me since I'm a beginner in C. I can understand
how the bit works, but I still don't have so much clue how to get to the
pixels. I presume there is an array of bits that I can modify, how to
get to this array of bits?
As far as I understood I could get the bitmap doing:
BitmapPtr bmp = WinGetBitmap(myOffScreenWindow);
I can't find from the api the function to get the bits from a BitmapPtr.
Any help will be very appreciated.
Many thanks, chr
