# Gimp-2.10.30

## Introduction to Gimp

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

This package is known to build and work properly using an LFS-11.1 platform.

### Package Information

- Download (HTTP): https://download.gimp.org/pub/gimp/v2.10/gimp-2.10.30.tar.bz2

- Download MD5 sum: 564fe77da27eaa4dfc73dc8358733d24

- Download size: 30 MB

- Estimated disk space required: 885 MB (194 MB installed, add 814 MB for tests)

- Estimated build time: 2.0 SBU (Using parallelism=4; add 0.5 SBU for tests)

### Additional Downloads

### Note

Updating the help files is still a work in progress, with large parts of the text for many languages not yet translated. The file below is a git snapshot.

- Download (HTTP): https://anduin.linuxfromscratch.org/BLFS/gimp/gimp-help-2021-03-30.tar.xz

- Download size: 170 MB

- Download MD5 sum: df6acc812c829b610d621f8e6973a680

- Estimated disk space required: From 383 MB (en only) to 1.8 GB (all 17 languages)

- Estimated build time: 1.8 SBU (en only), 14.0 SBU, with parallelism=4, for all languages

### Gimp Dependencies

#### Required

gegl-0.4.34, gexiv2-0.14.0, glib-networking-2.70.1, GTK+-2.24.33, HarfBuzz-3.4.0. libjpeg-turbo-2.1.2, libmypaint-1.6.1, librsvg-2.52.6, libtiff-4.3.0, Python2 libxml2-2.9.13 module (to build the translated help files), Little CMS-2.13.1, mypaint-brushes-1.3.1, Poppler-22.02.0 (including poppler-data) and a graphical environment

#### Recommended

dbus-glib-0.112, ghostscript-9.55.0 (with libgs installed), ISO Codes-4.9.0, libgudev-237, PyGTK-2.24.0 (including the gtk, pango and pangocairo modules) and xdg-utils-1.1.3

#### Optional

AAlib-1.4rc5, alsa-lib-1.2.6.1, Gvfs-1.48.1 (to access the online help), libmng-2.0.3, libwebp-1.2.2, OpenJPEG-2.4.0, an MTA (that provides a sendmail program), GTK-Doc-1.33.2, appstream-glib, libbacktrace, libheif with libde265 (both needed to read macOS heic images), libunwind, libwmf, and OpenEXR

When you have run configure, you will see that WebKit is not found - that dependency is for the legacy webkit-1.0 which should never be used on a modern system exposed to the internet.

#### Optional, for building the help system

dblatex (for PDF docs), pngnq and pngcrush to optimize the png files, but see the note on the help download above

User Notes: https://wiki.linuxfromscratch.org/blfs/wiki/gimp

## Installation of Gimp

Install Gimp by running the following commands:

    ./configure --prefix=/usr --sysconfdir=/etc &&
    make

To test the results (requires an X-Windowed terminal) issue: make check.

Now, as the `root` user:

    make 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+-2.24.33 or GTK+-3.24.31 installed (for the icon cache) and desktop-file-utils-0.26 (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. Because of the issues mentioned in the note above, you are recommended to use the online help, either by building against Gvfs-1.48.1 so that 'help' can open the latest XML files in your browser, or else you can manually open the html in your browser by going to https://docs.gimp.org/2.10/en (change the language code if desired).

If you nevertheless 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. Prepare for the build with the following command:

    ALL_LINGUAS="ca da de el en en_GB es fi fr it ja ko nn pt_BR ro ru zh_CN" \
    ./autogen.sh --prefix=/usr

Remove from `ALL_LINGUAS` the codes for any languages which you do not wish to install. Alternatively, remove the line starting with `ALL_LINGUAS`, if you wish to build all languages.

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/2.0/help

## Command Explanations

`ALL_LINGUAS="ca da de el en en_GB ..."`: by default, the help files will be rendered in all the available languages. Remove the codes of any languages you do not wish to build.

`--disable-python`: This option is necessary if you have not installed PyGTK.

`--enable-gtk-doc`: Use this parameter if GTK-Doc is installed and you wish to rebuild and install the API documentation.
