[silva-dev] PIL problem
x at vex.net
Wed Sep 14 23:14:25 CEST 2005
Just upgrading to 1.3. Creating test instances of Silva Root... if while doing
so i have the "Add Silva Documentation" box checked, i get the following
The version of PIL installed is 1.1.5, which appears to be the latest.
It is odd though, because running `file` on all of the *.png identifies them
So I tossed in a print self.id at Silva/Image.py line 449 and it is
"accesstabslender.jpg" which is causing the problem.. hmm... jpg...
grep doesn't seem to find that id anywhere in source code... is it being
generated? Tracing... tracing... (i'm writing all this out for your
amusement... at my Silvanic ignorance...) hrm... silva.xml? AH!
silva_docs.zip ... so that's how stuff is bundled up... cool... er... what?
The file is coming from the net?!! (<silva-extra location> tag)...
accesstabslender.jpg 100% of 1813 B 3117 kBps
$ file accesstabslender.jpg
accesstabslender.jpg: PNG image data, 538 x 28, 8-bit/color RGB, interlaced
Ah indeed. So maybe you want to avoid interlaced PNGs (unfortunately) if using
