[comp.sys.mac.programmer] Help wanted with file format

Hi,there,

I've just started learning to program the Mac.  
My immediate goal is to set up a line drawing
program to process some weird lab data. Now here
is the problem: how do you output the graphics 
into a file in MacPaint format, so that I can
just read the output directly into MacPaint to
add some nuts and bolts to the picture? This
might sound easy for you guys, but give the
starter a hand please.

I would appreciate if you can give me some ref.
lists or share with me pieces of code you have
already.

Thanks!

See if you can find a copy of Tech Note 86, which describes the file
format in detail, and gives C and Pascal examples for reading and writing
the file. LightSpeed C version 4 comes with source code, in art class, to
do this directly. Claris also publishes a tech note with this information,
and lastly, you probably should be writing PICT files, which can be read
by MacDraw, among others, since they don't restrict you to MacPaint's
576x720 bitmap, but let you use as much resolution as you want. A PICT
file is simply the data from a PicHandle preceded by 512 bytes of 0. 
See Tech note 154.
