Description Marcos H. Woehrmann 2009-04-05 20:21:37 UTC

The attached file generates a "Error: /rangecheck in --.execform1--" error when processed by 
Ghostscript head (r9614) and earlier versions that I tried.  Adobe Acrobat 9 and Apple Preview both open 
the file without error (it opens as a blank page, but according to the customer that is correct).

The command line I'm using for testing:

  bin/gs -sDEVICE=tiff24nc -o test.tif ./samplesB1a1.pdf

patch

Skip Identity /TR function in soft mask dictionary on PostScript level instead
of
passing {} to .begintransparencymaskgroup because ref_function() only accepts
functions that consist of data and %execfunction .

The patch is committed as a rev. 9617.
Regression testing shows no differences.
