           Summary: Multiple issues with tiffsep (wrong colors and a
                    regression and large memory usage)
           Product: Ghostscript
           Version: HEAD
          Platform: Macintosh
        OS/Version: MacOS X
            Status: NEW
          Severity: normal
          Priority: P4
         Component: Other Driver
        AssignedTo: support at artifex.com
        ReportedBy: marcos.woehrmann at artifex.com
         QAContact: gs-bugs at ghostscript.com

The customer reports that the attached PDF file generates the wrong colors when converted by 
Ghostscript 8.63 using the tiffsep device.  Additionally, when using gshead (r9198) Ghostscript doesn't 
generate an output file, but instead reports a seg fault.  Finally, this file uses a large amount (1 gig) of 
memory when processed by Ghostscript, even at 72dpi (the output file size is just over 22 megs (1984 
x 2835 x 4).

The command line I"m using for testing:

  bin/gs -sDEVICE=tiffsep -o test.tif ./Pantone.pdf

The first revision which shows the core dump is r9071:

Fix : Divide gdevp14.c into 2 modules.

DETAILS :

This change is syntactically equivalent.
The purpose is to minimize dependencies between projects.
The new module gxblend1.c keeps color blending algorithms moved from gdevp14.

EXPECTED DIFFERENCES :

None.
