Hi, I couldnt find any info about this from other sources, so I decided
to ask.

I would like to find a utility (PC-based or C-source) which takes a gif
file, and converts it in the following fashion:

The color numbers are re-ordered so that near-to-each-other pixels are 
near to each other in color number; 

and The picture is re-compressed using thefollowing ordering of pixels:

--------->
^------->|
|^----->||
|<------v|
<--------v
          
(Hopefully making the compression more efficient...

If such an option exists in PBMPLUS, then which option is it, and where can
I find a pre-compiled for IBM PC version of PBMPLUS?

Thank you for your time.
