Hi there,
one of my peer developers at my office has the following question regarding 

I have a 3-band color tiff file. Can I use the gdal library to convert it to 
one-bit 4 group b&w tiff? If yes, how can I implement it?

The problem we are facing is to create png and b&w tiffs from ArcMap layout 
through code (VB). The only other solution (we know if currently) is getting 
a license for ArcPress, yet this would be fairly expensive and would require 
additional CPU/memory resources. Does anybody know of any other possible
