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.
Note
Development versions of BLFS may not build or run some packages properly if LFS or dependencies have been updated since the most recent stable versions of the books.
Package Information
Gdk Pixbuf Dependencies
Required
GLib-2.78.3, libjpeg-turbo-3.0.1, libpng-1.6.40, and shared-mime-info-2.4
Recommended
docutils-0.20.1, librsvg-2.57.1 (runtime dependency, needed for loading symbolic icons) and libtiff-4.6.0
Optional (Required if building GNOME)
gobject-introspection-1.78.1
Optional
Gi-DocGen-2023.3 (to generate documentation), libavif-1.0.3 (runtime dependency, needed for loading AVIF images), and webp-pixbuf-loader-0.2.4 (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 &&
ninja
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.build &&
meson configure -Dgtk_doc=true &&
ninja
To test the results, issue: ninja test. The tests make a heavy use of disk.
Now, as the root
user:
ninja install
Note
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.
