[gs-devel] PDF to Tiff conversion issue with large Bmps.

[BSmith]

I've uploaded a test file if you would like to look at it.
One question I have is how do you reduce color depth?  The various bpp
commands I tried do not seem to have any effect on the Tiff file size.
PDF Page size is 8.5 x 14.
I want a monochrome Tiff for output.  

Thanks,
BSmith
