OK, so I picked up the best of both worlds, THINK C and AZTEC C, one for
my MAC moods and one for my Unix'ish moods.

I finally found a couple of decent books regarding C on a Mac, as the
manuals supplied with the above products aren't much use for starting
out (well for the price you can't complain) and my Pascal is rusty by 
about 5 years.

As graphics is my living, I decided it would be nice to be able to
view some of those 32-bit images I render at work, and at least view
them in 8-bits at home, so my first application...

I must admit, I started grumbling a little when I first started
investigating the Mac libraries (Managers), but after a while I began
to appreciate how fast you can put something together.

So after one night, I can find, read and display PICT files.

OK, so what if I wan't to process the data before displaying it on the
screen. QDprocs look a little hairy to start messing with right off the bat, 
and anyway my ultimate goal with this application is to convert image formats 
that I work in and display them on the Mac.

This is where I've run into a brick wall, could some kind soul give me
some tips on how to go about say, displaying a 256x256 type char array 
on the screen?

Other libraries I work with on my Unix machines have routines like 
writeRGB(xres, rbuf, gbuf, bbuf) for scanlines or similar routines
for rectangular areas.

Now I realize the Mac is a different environment, but there must be a
fairly simple way to accomplish this feat.

Any help will be greatly appreciated.
