[solved] Issue with GTK-2 and SVG images

[ljfr]

Hi, I cannot open SVG images with few GTK-2 based applications starting from a vanilla 4.30, 2 examples:
-with gpicview-0.1.9 from the official repo, try to open a svg image, I get:

Code: Select all

Couldn't recognize the image file format for file 'book.svg'

-If you compile gcompris-8.4.12, you get an error message "Could't find or load ... strategy.svg" on the first panel,which seems to come from this line 85 in gameutil.c:
pixmap = gdk_pixbuf_new_from_file(filename,NULL);
where it fails to load the svg images, this was also experienced by pccampbell87 on puppy 4.20 on this post:
http://www.murga-linux.com/puppy/viewto ... 0&start=15

I am starting from a vanilla 4.3, so all those libraries are installed: libcairo2, librsvg2, ... the module /usr/lib/gtk-2.0/2.10.0/loaders/svg_loader.so, ...

A way to solve this problem is to install a slackware 12.2 version of GTK-2 -using gslapt:
gtk+2-2.12.12-i486-1.tgz
...but I would rather use a puppy officially package GTK-2 version, can
someone check that it is really a gtk-2 issue?

Hi,

where can I find compilations option used for this package:
gtk+-2.14.7-pup4

regards,

gtk:

./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var --build=i486-pc-linux-gnu --with-xinput=yes --enable-debug=minimum

SVG support is not provided by the GTK package, it is provided by 'librsvg'.

To configure librsvg:

# ln -s seamonkey-config /usr/bin/mozilla-config
# ./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var --build=i486-pc-linux-gnu --enable-pixbuf-loader --enable-mozilla-plugin --with-svgz

You may find that if you compile 'libcroco', an optional dependency of librsvg, that may give wider SVG support.

Hi, thanks for your guidelines,

it seems we just have to update shared-mime-info, I tried the last version 0.70, and it solved the issue (tested with viewnor and gqview),see:
http://library.gnome.org/devel/gtk/unst ... lding.html
http://www.freedesktop.org/wiki/Softwar ... -mime-info

If you want to investigate further, some clues:

on gtk 2.14, gdk-pixbuf changes
* Support loading OS X icns format
* Support loading JPEG 2000 images
* Support loading and saving to GIO streams
* Use GIO for mime information

Code: Select all

Release notes for 2.14
======================
...

* gdk-pixbuf will use GIO for mime type detection if possible. For
  this to work, shared-mime-info needs to be installed and XDG_DATA_DIRS
  set accordingly at configure time. Otherwise, gdk-pixbuf falls
  back to its built-in sniffing implementation.
