           Summary: PostScript to TIFF - Differences between Ghostscript

Created an attachment (id=7140)
 --> (http://bugs.ghostscript.com/attachment.cgi?id=7140)
Source Post Script file

Using the switches:

-sDEVICE=tiffpack -r1016x1016 -dNOPAUSE -dBATCH

Ghostscript v8.54 converts the attached postscript file 0000_BLK.PS to
BLK0000_V8_54.TIF

However, I cannot read this file using LIBTIFF v3.9.4; I get the error:

"TIFFReadDirectory: Warning, C:\Temp\Ps_to_Tiff_data\BL30000.TIF: unknown field
with tag 292 (0x124) encountered."

When I use Ghostscript v9.00 I can successfully read the TIFF file but the
graphics in the output file BLK0000_V9_00.TIF are corrupted (there are white
pixels in what should be solid black areas.

Is there a solution to this?
