Introduction to Gdk Pixbuf

The Gdk Pixbuf package is a toolkit for image loading and pixel buffer manipulation. It is used by 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]

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-2.86.1 (GObject Introspection required for GNOME) and shared-mime-info-2.4

Recommended

docutils-0.22.2 and glycin-2.0.4

Optional

Gi-DocGen-2025.5 (to generate documentation), libavif-1.3.0 (runtime, deprecated), libjpeg-turbo-3.0.1 (deprecated), libjxl-0.11.1 (runtime, deprecated), libpng-1.6.50 (deprecated), librsvg-2.61.2 (runtime, deprecated), and libtiff-4.7.1 (deprecated)

Installation of Gdk Pixbuf

Install Gdk Pixbuf by running the following commands: 

mkdir build &&
cd    build &&

meson setup ..            \
      --prefix=/usr       \
      --buildtype=release \
      -D others=enabled   \
      --wrap-mode=nofallback &&
ninja

If you have Gi-DocGen-2025.5 installed and wish to build the API documentation for this package, issue: 

sed "/docs_dir =/s@\$@ / 'gdk-pixbuf-2.44.4'@" -i ../docs/meson.build &&
meson configure -D gtk_doc=true                                        &&
ninja

The test suite of this package does not provide meaningful results.

Now, as the root user: 

ninja install
[Note]

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, preventing it from downloading any optional dependencies which are not installed on the system.

-D others=enabled: Build the loaders for some formats not supported by glycin yet, notably XBM and XPM.

Short Descriptions

gdk-pixbuf-csource

is a small utility that generates C code containing images, used for compiling images directly into programs

gdk-pixbuf-pixdata

is a tool used to convert GdkPixbuf to GdkPixdata
