# Gimp-3.2.4

## Introduction to Gimp

The Gimp package contains the GNU Image Manipulation Program which is useful for photo retouching, image composition and image authoring.

## Installation of Gimp

If upgrading from a previous Gimp-3 installation, as the `root` user, remove some files and directories from the old installation or the build system may mistakenly pick them up, causing a build failure:

    rm -rf /usr/{lib,share}/gimp/3.0 &&
    rm -f  /usr/share/gir-1.0/Gimp-3.0.gir &&
    rm -f  /usr/lib/girepository-1.0/Gimp-3.0.typelib &&
    rm -f  /usr/lib/libgimp*-3.0.so*

Upstream provides a patch for building against gexiv2-0.16.0 and later. Use it as follows:

    patch -Np1 -i build/macos/patches/0001-build-macos-Do-not-require-gexiv2-0.14-on-homebrew.patch

Install Gimp by running the following commands:

    mkdir gimp-build &&
    cd    gimp-build &&

    meson setup ..            \
          --prefix=/usr       \
          --buildtype=release \
          -D headless-tests=disabled &&
    ninja

To test the results (requires a terminal in a graphical environment) issue: ninja test. Three tests, `gimp:app / save-and-export`, `gimp:app / single-window-mode`, and `gimp:app / ui`, are known to fail.

Now, as the `root` user:

    ninja install

### Note

This package installs icon files into the `/usr/share/icons/hicolor` hierarchy and desktop files into the `/usr/share/applications` hierarchy. You can improve system performance and memory usage by updating `/usr/share/icons/hicolor/index.theme` and `/usr/share/applications/mimeinfo.cache`. To perform the update you must have GTK-3.24.52 installed (for the icon cache) and desktop-file-utils-0.28 (for the desktop cache) and issue the following commands as the `root` user:

    gtk-update-icon-cache -qtf /usr/share/icons/hicolor &&
    update-desktop-database -q

## Installation of Gimp-Help

The `gimp-help` tarball contains images and English text help for help files, together with translations. If you wish to install local copies of the help files to read offline, unpack the gimp-help tarball and change into the root of the newly created source tree.

    tar -xf ../../gimp-help-3.2.0.tar.bz2 &&
    cd gimp-help-3.2.0

    sed -i 's/import libxml2//' configure &&

    ALL_LINGUAS="en" \
    ./configure --prefix=/usr

Building non-English languages is only possible with the libxml2 Python 3 module, which is deprecated and no longer enabled in the BLFS libxml2 build.

Now build the help files:

    make

Issue the following commands as the `root` user to install the help files:

    make install &&
    chown -R root:root /usr/share/gimp/3.0/help

## Command Explanations

`-D headless-tests=disabled`: This switch disables using xvfb-run for running the tests. Without this switch, many tests fail if xvfb-run has been installed.

### Short Descriptions

gimp-3.0 | is the GNU Image Manipulation Program. It works with a variety of image formats and provides a large selection of tools
gimp-console-3.0 | is a console program that behaves as if The Gimp was called with the `--no-interface` command-line option
gimptool-3.0 | is a tool that can build plug-ins or scripts and install them if they are distributed in one source file. gimptool-3.0 can also be used by programs that need to know what libraries and include-paths The Gimp was compiled with
`libgimp-3.0.so` | provides C bindings for The Gimp's Procedural Database (PDB), which offers an interface to core functions and to functionality provided by plug-ins
`libgimpbase-3.0.so` | provides the C functions for basic Gimp functionality such as determining enumeration data types, gettext translation, determining The Gimp's version number and capabilities, handling data files and accessing the environment
`libgimpcolor-3.0.so` | provides the C functions relating to RGB, HSV and CMYK colors as well as converting colors between different color models and performing adaptive supersampling on an area
`libgimpconfig-3.0.so` | contains C functions for reading and writing config information
`libgimpmath-3.0.so` | contains C functions which provide mathematical definitions and macros, manipulate 3x3 transformation matrices, set up and manipulate vectors and the MD5 message-digest algorithm
`libgimpmodule-3.0.so` | provides the C functions which implement module loading using GModule and supports keeping a list of GimpModule's found in a given searchpath
`libgimpthumb-3.0.so` | provides the C functions for handling The Gimp's thumbnail objects
`libgimpui-3.0.so` | contains The Gimp's common user interface functions
`libgimpwidgets-3.0.so` | contains The Gimp and GTK's widget creation and manipulation functions
