Description Ralph Giles 2006-06-26 21:20:43 UTC

Ghostscript fails on files that do not include a MediaBox. This is an invalid
file, but Acrobat and evince both render it.

The customer reports that gsview can also render the file given a target page
size. I'm not sure if this is a regression or if there's a work-around.

Note:  The file works with 8.00 but not 8.11.

Comment 3 Ralph Giles 2006-06-27 11:24:20 UTC

Customer suggested just using /PageSize from the currrentpagedevice dict if the
/MediaBox pget fails.

Comment 4 Ralph Giles 2006-06-28 10:03:52 UTC

we'll do this.

Comment 5 Alex Cherepanov 2006-06-28 15:58:32 UTC

Ralph, I want this bug because it affects the same parts of the code
as bug 688744, which is already assigned to me.

The proposed patch for the bug 688744 assumes that /MediaBox is always
present. Probably, the patch should be modified to fix both bugs.

Comment 6 Ralph Giles 2006-06-28 16:12:22 UTC

Fine by me. The fix is straightforward.

patch

Use /PageSize from the currrent page device dictionary when the /MediaBox pget
fails.

DIFFERENCES:
Testing now.

The fix for the bug 688744 will be updated after this fix is committed.

Comment 8 Alex Cherepanov 2006-07-03 07:53:19 UTC

There's no significant differences.

Insignificant differences are:
409-01.ps - different order of file enumeration reflected in the raster
215-01.ps - different order of file enumeration in stdout only
Bug687615.ps - different order of dictionary enumeration in stdout only.
Multiple differences in generated PDF files in Type1C streams.

Comment 10 Alex Cherepanov 2006-07-05 11:25:04 UTC

The patch is committed as revision 6893.
