Introduction to Gdk Pixbuf

The Gdk Pixbuf package is a toolkit for image loading and pixel buffer manipulation. It is used by GTK+ 2 and GTK+ 3 to load and manipulate images. In the past it was distributed as part of GTK+ 2 but it was split off into a separate package in preparation for the change to GTK+ 3.

This package is known to build and work properly using an LFS 12.1 platform.

Package Information

Gdk Pixbuf Dependencies


GLib-2.78.4, libjpeg-turbo-3.0.1, libpng-1.6.42, and shared-mime-info-2.4


Optional (Required if building GNOME)



Gi-DocGen-2023.3 (to generate documentation), libavif-1.0.4 (runtime dependency, needed for loading AVIF images), and webp-pixbuf-loader-0.2.7 (runtime dependency, needed for loading WebP images)

Installation of Gdk Pixbuf

Install Gdk Pixbuf by running the following commands:

mkdir build &&
cd    build &&

meson setup ..            \
      --prefix=/usr       \
      --buildtype=release \
      --wrap-mode=nofallback &&

If you have Gi-DocGen-2023.3 installed and wish to build the API documentation for this package, issue:

sed "/docs_dir =/s@\$@ / 'gdk-pixbuf-2.42.10'@" -i ../docs/ &&
meson configure -Dgtk_doc=true                                         &&

To test the results, issue: ninja test. The tests make a heavy use of disk.

Now, as the root user:

ninja install


If you installed the package on to your system using a DESTDIR method, an important file was not installed and should be copied and/or generated. Generate it using the following command as the root user:

gdk-pixbuf-query-loaders --update-cache

Command Explanations

--buildtype=release: Specify a buildtype suitable for stable releases of the package, as the default may produce unoptimized binaries.

--wrap-mode=nofallback: This switch prevents meson from using subproject fallbacks for any dependency declarations in the build files, stopping it downloading any optional dependency which is not installed on the system.

-Dman=false: Use this option if you do not want to generate manual pages, or if you do not want to install docutils-0.20.1.
