I'm looking for a references describing available raster compression
algorithms and associated file formats.  

My application is to display large raster images fast on an IBM/PC.
The requirement includes allowing viewing portions of the image
at different scales.  My work so far has led me to the conclusion
that the only way to get fast (< 2 second) response times is to 
have several scales of the same image available. Thus, limiting
the user to view at preset scales.

My definition of large is E size engineering drawings scanned
at 200 dpi.  That would be 7200 by 8000 pixels. Oh yea, don't
need color or gray scale.

I would appreciate any advice and pointers to appropriate 
literature.
