bitmap bits of a memory DC
Posted on 2001-08-15
I've created a CDC, with the right height, width, palette (1 bit), etc. I draw some texts, bitmaps, etc.
I have to access the bits of the CDC, because I want to print it on a special printer that needs pixels as bits.
GetPixel works at all, but very slow. About 1.2 sec when I process the whole DC (pixel by pixel).
Are there any faster way to access the bits ?
I try to use the following:
unsigned char *bbmp=new unsigned char[width*height];
But all of the bits are 0.
What can I do ?
