9694.0. "X Program Display problems" by SWAM1::POIANI_MI () Thu May 01 1997 20:38
I have a customer bringing some X widows code over from an SGI box.
They have this question:
The man pages (and the header files) indicate that a pixel is a 64-bit
value (a long). If I allocate space for an W x H image do really need
W*H*8 bytes? This seems awfully wasteful as no display servers support
64-bit pixel values (32 is typical). The problem is that I have a
program which allocates W*H*sizeof(long) for the image. This works
fine on the 32-bit machines but not on my DEC alpha (the image displays
wrong). The question is are pixels 32 or 64 bit (int or long)?
