# gdk-pixbuf-2.42.2

## 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-10.1 platform.

## Installation of Gdk Pixbuf

Install Gdk Pixbuf by running the following commands:

    mkdir build &&
    cd build &&

    meson --prefix=/usr .. &&
    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

`-Dgtk_doc=true`: Use this parameter if GTK-Doc is installed and you wish to rebuild and install the API documentation.
