  13. Hi NeRDs,
  14.  
  15. Yes, I have encountered that problem with JPEG also, and with bright blue
  16. images too.  I didn't look at the .tiff, but I'll bet you used PoV
  17. (original poster please write me if you want to chat about it, I use it
  18. a lot).  I gave up and now use horizontal differencing in LZW compression
  19. for pretty good results.  Try compiling the PBMplus utilities, they work
  20. really well.  I don't like the thought that JPEG is lossy anyway.
  21.  
  22. Regards,
  23.
