# gdk-pixbuf-2.38.0

## 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-8.4 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

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

`-Djasper=true`: If you've installed JasPer-2.0.14 and you want Gdk Pixbuf to use it to compile a JPEG2000 image loader, pass this switch to configure.

## Contents

Installed Programs: gdk-pixbuf-csource, gdk-pixbuf-pixdata, gdk-pixbuf-query-loaders, and gdk-pixbuf-thumbnailer,
Installed Libraries: libgdk_pixbuf-2.0.so and libgdk_pixbuf_xlib-2.0.so
Installed Directories: /usr/{include,lib}/gdk-pixbuf-2.0, /usr/share/installed-tests/gdk-pixbuf, /usr/share/gtk-doc/html/gdk-pixbuf, and /usr/share/thumbnailers

### 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.
gdk-pixbuf-query-loaders | collects information about loadable modules for Gdk Pixbuf and writes it to the default cache file location, or to stdout.
gdk-pixbuf-thumbnailer | creates thumbnails of pictures for use in other applications.
`libgdk_pixbuf-2.0.so` | contains functions used to load and render images.
