GIMPRC(5)

NAME
gimprc - gimp configuration file

DESCRIPTION
The gimprc file is a configuration file read by GIMP when it starts up. There are two of these: one system-wide one stored in /etc/gimp/2.0/gimprc and a per-user $XDG_CONFIG_HOME/GIMP/2.10/gimprc which may override system settings. Comments are introduced by a hash sign (#), and continue until the end of the line. Blank lines are ignored. The gimprc file associates values with properties. These properties may be set by lisp-like assignments of the form:

    (property-name value)

where:

property-name
    is one of the property names described below.

value
    is the value the property is to be set to.

Either spaces or tabs may be used to separate the name from the value.

PROPERTIES
Valid properties and their default values are:

(temp-path "${gimp_temp_dir}")
    Sets the folder for temporary storage. Files will appear here during the course of running GIMP. Most files will disappear when GIMP exits, but some files are likely to remain, so it is best if this folder not be one that is shared by other users. This is a single folder.

(swap-path "${gimp_cache_dir}")
    Sets the swap file location. GIMP uses a tile based memory allocation scheme. The swap file is used to quickly and easily swap tiles out to disk and back in. Be aware that the swap file can easily get very large if GIMP is used with large images. Also, things can get horribly slow if the swap file is created on a folder that is mounted over NFS. For these reasons, it may be desirable to put your swap file in "/tmp". This is a single folder.

(swap-compression "fast")
    The compression method used for tile data stored in the swap file. This is a string value.

(num-processors 1)
    Sets how many threads GIMP should use for operations that support it. This is an integer value.

(tile-cache-size 2g)
    When the amount of pixel data exceeds this limit, GIMP will start to swap tiles to disk. This is a lot slower but it makes it possible to work on images that wouldn't fit into memory otherwise. If you have a lot of RAM, you may want to set this to a higher value. The integer size can contain a suffix of 'B', 'K', 'M' or 'G' which makes GIMP interpret the size as being specified in bytes, kilobytes, megabytes or gigabytes. If no suffix is specified the size defaults to being specified in kilobytes.

(use-opencl no)
    When enabled, uses OpenCL for some operations. Possible values are yes and no.

Specifies the language to use for the user interface.  This is a string value.

(interpolation-type cubic)
    Sets the level of interpolation used for scaling and other transformations. Possible values are none, linear, cubic, nohalo and lohalo.

(default-threshold 15)
    Tools such as fuzzy-select and bucket fill find regions based on a seed-fill algorithm. The seed fill starts at the initially selected pixel and progresses in all directions until the difference of pixel intensity from the original is greater than a specified threshold. This value represents the default threshold. This is an integer value.

PATH EXPANSION
Strings of type PATH are expanded in a manner similar to bash(1). Specifically: tilde (~) is expanded to the user's home directory. Note that the bash feature of being able to refer to other user's home directories by writing ~userid/ is not valid in this file. ${variable} is expanded to the current value of an environment variable. There are a few variables that are pre-defined:

gimp_dir
    The personal gimp directory which is set to the value of the environment variable GIMP2_DIRECTORY or to $XDG_CONFIG_HOME/GIMP/2.10.

gimp_data_dir
    Base for paths to shareable data, which is set to the value of the environment variable GIMP2_DATADIR or to the compiled-in default value ${datarootdir}/gimp/2.0.

gimp_plug_in_dir
    Base to paths for architecture-specific plug-ins and modules, which is set to the value of the environment variable GIMP2_PLUGINDIR or to the compiled-in default value ${exec_prefix}/lib/gimp/2.0.

gimp_sysconf_dir
    Path to configuration files, which is set to the value of the environment variable GIMP2_SYSCONFDIR or to the compiled-in default value /etc/gimp/2.0.

gimp_cache_dir
    Path to cached files, which is set to the value of the environment variable GIMP2_CACHEDIR or to the system default for per-user cached files.

gimp_temp_dir
    Path to temporary files, which is set to the value of the environment variable GIMP2_TEMPDIR or to the system default for temporary files.

FILES

/etc/gimp/2.0/gimprc
    System-wide configuration file
