Subject: libsdl-image1.2: Some corrupted images (supertux and vor)

Date: Sun, 22 Jan 2012 17:36:11 -0500

[Message part 1 (text/plain, inline)]

Package: libsdl-image1.2
Version: 1.2.11-1
Severity: normal

Hi, about half the graphics in vor (which are loaded from .png
files by sdl_image) are now corruptid, as of the upgrade from
libsdl-image1.2 1.2.10-3 to 1.2.11-1. I found that one of the
graphics in supertux is corrupted in a similar way.

The images appear at about 1/3 their intended width, with the
colors all messed up.

Attached is a screenshot from supertux (the question boxes should
be the same width as the wooden ones) and one from vor (the speckly
ovals should also look like rocks.)

Thank you.

     - Jason

It seems to happen with the images from colormaps (output from "file
b_game.png"):

b_game.png:       PNG image data, 269 x 91, 4-bit colormap, non-interlaced

This is one of the images in VOR for the title, and the image for
"[remaining] lives" (life.png, appearing in the top-left corner) has
the same issue, and some of the rocks but not all:

rock00.png:       PNG image data, 19 x 20, 8-bit colormap, non-interlaced
rock01.png:       PNG image data, 26 x 30, 8-bit/color RGB, non-interlaced
rock02.png:       PNG image data, 37 x 35, 8-bit/color RGB, non-interlaced
rock03.png:       PNG image data, 23 x 25, 8-bit colormap, non-interlaced
rock04.png:       PNG image data, 32 x 30, 8-bit/color RGB, non-interlaced
rock05.png:       PNG image data, 21 x 21, 8-bit colormap, non-interlaced
rock06.png:       PNG image data, 24 x 25, 8-bit colormap, non-interlaced
rock07.png:       PNG image data, 42 x 40, 8-bit/color RGB, non-interlaced
...

Can you please confirm if it's the same issue with supertux?

Thanks for reporting.

I'd say this should be bumped to serious, because it breaks other
software, and it's a regression that should not transition to testing.

The same happens with the mana client, the initial menus are all
messed up.

Agree, but I picked up a patch from upstream and just uploaded a new
debian revision that hopefully it will fix the problem.  So if this
patch fixes the problem for everybody that's it, otherwise I will do
what you suggest.

It works for me with vor, and IIRC it fixes Mana for Mageia folks.  Please test!

Cheers.

Confirmed!

The only images in supertux/data/tilesets with color type 3 (rgb
indexed color) are the question box, and three other powerup boxes
(which I didn't see in my play-through of level 1).


Good catch!

I'm surprised that not all the rock images use the same color type,
because they are all generated with the same script, renderer, and
even source file. Guess pnmtopng is doing some optimizing.


Now to report a bug in imagemagick's identify command (which gives
conflicting information w/wo the -verbose flag)...

Thanks for the fix!

The new version:

libsdl-image1.2-dev_1.2.11-2

works great for me. Both with supertux and vor.
