Line Drawing Algorithms

Hi there, I''ve been trying to use Bresenham''s line drawing algorithm in a 16-bit mode on a 640x480 screen. But when I use it, the diagonal lines have these gaping "holes" in them (a couple pixels wide at least). Needless to say, it looks like crap. Anyone have any suggestions? Sorry if this is a lame question, but I couldn''t find any decent answers elsewhere.

Are you sure its a 16 bit surface?? (not 24 or 32 bit)

maybe it's some weird kind of surface

Yes! Got it!

I was right about the casting...It didn''t like the UCHAR* bit. I changed all the pointers to surfaces from UCHAR* to WORD*, and it came out great!

Thanks for all the help!
