Subject: bug#22442: 25.0.50; --with-cairo does not display PNG on GNU/Linux
Date: Sat, 23 Jan 2016 00:27:08 -0800 [thread overview]
Message-ID: <56A3395C.4040208@cs.ucla.edu> (raw)
To reproduce the problem, configure Emacs --with-cairo, and then run these shell
commands:
wget https://upload.wikimedia.org/wikipedia/commons/f/f5/All_palaeotemps.png
emacs -Q All_palaeotemps.png
Emacs shows a blank (or sometimes garbled) screen instead of the image.
I think the problem is that lookup_rgb_color is returning garbage.
Here are more details about the configuration, built on Fedora 23 x86-64:
In GNU Emacs 25.0.50.55 (x86_64-unknown-linux-gnu, GTK+ Version 3.18.6, cairo
version 1.14.2)
