PDF file that creates invalid PostScript output with pdftops (691.44 KB, application/pdf)

Description Joseph Karolchik 2011-07-18 13:36:08 UTC 
I am working with several large GeoPDF files from the US Geological Survey that are causing a problem when converted to a PostScript output file using pdftops. For this example, I used the latest stable release, but the problem exists in earlier releases as well.

> pdftops -v
pdftops version 0.16.7
Copyright 2005-2011 The Poppler Developers - http://poppler.freedesktop.org

I generate the output PostScript file using the following command:

> pdftops -preload geoFile.pdf geoFile.ps

The file contains layered data defined in Optional Content Groups, and some of the OCGs cause an error message to be output, as follows:

Error: Could not find a OCG with Ref (65:0)
Error: Could not find a OCG with Ref (70:0)
Error: Could not find a OCG with Ref (75:0)
Error: Could not find a OCG with Ref (78:0)
Error: Could not find a OCG with Ref (89:0)
Error: Could not find a OCG with Ref (92:0)
Error: Could not find a OCG with Ref (93:0)
<etc>

Also, this error sometimes is output:

Error: XObject 'Tile_0000_0000' is unknown
Error: XObject 'Tile_0000_0001' is unknown
Error: XObject 'Tile_0000_0002' is unknown
Error: XObject 'Tile_0000_0003' is unknown
Error: XObject 'Tile_0001_0000' is unknown
Error: XObject 'Tile_0001_0001' is unknown
Error: XObject 'Tile_0001_0002' is unknown
Error: XObject 'Tile_0001_0003' is unknown
<etc>


If I try to open the file in a graphics viewer, it hangs when I try to open it (or creates a blank screen).  If I use ghostScript to interpret the file using ps2pdf, it will generate either a rangecheck or stack overflow error.


Note that if I don't use the "-preload" option that the PostScript output file is usable, but missing some of the layers.

Can you attach a file that is giving you this problem?

I attached a sample file.  I needed to down convert it because it was originally too big for Bugzilla, and I wanted to verify that the smaller size file still generated the error (it does).
