Description Ralph Giles 2007-03-24 16:04:28 UTC 
The file fails with head (at least r7797) when using the x11alpha device at
resolutions below 300dpi. It does not seem to occur with the x11 device, with or
without -dTextAlphaBits=4 or -dGraphicsAlphaBits=4.

Still an issue with 8.70rc1. Passing to Michael along with the rest of the
x11alpha transparency/alpha bugs.

Problem still present in 8.71 and also in SVN rev 11415.
Comment 6 Paul Schreiber 2010-08-28 21:05:04 UTC 
I see the error with 7.07 and 8.64. However, version 8.71 is working fine on my file.

Transparency/alpha type of bugs are usually sensitive to resources - just to be sure, are you testing on the same box?

 I ran in to this using MediaWiki and made detailed notes on their support page:
http://www.mediawiki.org/wiki/Manual_talk:Image_Administration#Error_creating_thumbnail_convert:_missing_an_image_filename

Yes, same box, with successive command-line calls. Could be I have an edge case that *was* fixed. Just adding another data point.
Comment 9 Michael Vrhel 2011-04-09 04:54:48 UTC 
Fixed with rev 12380
