<title>Overview</title>
<para>
An icon theme is a set of icons that share a common look and
feel. The user can then select the icon theme that they want to
use, and all apps use icons from the theme. The initial user of
icon themes is the icon field of the desktop file specification,
but in the future it can have other uses (such as mimetype
icons).
</para>
<para>
From a programmer perspective an icon theme is just a
mapping. Given a set of directories to look for icons in and a theme
name it maps from icon name and nominal icon size to an icon filename.

<term>Icon Theme</term>
<listitem>
<para>
An icon theme is a named set of icons. It is used to map
from an iconname and size to a file. Themes may inherit
from other themes as a way to extend them.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>Icon file</term>
<listitem>
<para>
An icon file is an image that can be loaded and used as an
icon. The supported image file formats are PNG, XPM and SVG.
PNG is the recommended bitmap format, and SVG is for
vectorized icons. XPM is supported due to backwards
compability reasons, and it is not recommended that new
themes use XPM files. Support for SVGs is optional.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>Base Directory</term>
<listitem>
<para>
Icons and themes are searched for in a set of directories,
called base directories. The themes are stored in
subdirectories of the base directories.
</para>
</listitem>
</varlistentry>
</variablelist>
</sect1>
<sect1 id="directory_layout">
<title>Directory Layout</title>
<para>
Icons and themes are looked for in a set of directories. By
default, apps should look in $HOME/.icons (for backwards compatibility),
in $XDG_DATA_DIRS/icons and in /usr/share/pixmaps (in that order).
Applications may further add
their own icon directories to this list, and users may extend or
change the list (in application/desktop specific ways).In each of
these directories themes are stored as subdirectories. A theme can
be spread across several base directories by having subdirectories of
the same name. This way users can extend and override system
themes.
</para>
<para>
In order to have a place for third party applications to install
their icons there should always exist a theme called "hicolor"
<footnote><para>This name is chosen for backwards compatibility with the old
KDE default theme</para></footnote>.
The data for the hicolor theme is available for download at:
http://www.freedesktop.org/software/icon-theme/.
Implementations are required to look in the "hicolor" theme if
an icon was not found in the current theme.
</para>
<para>
Each theme is stored as subdirectories of the base
directories. The internal name of the theme is the name of the
subdirectory, although the user-visible name as specified by the
theme may be different. Hence, theme names are case sensitive, and
are limited to ASCII characters. Theme names may also not contain
comma or space.
</para>
<para>
In at least one of the theme directories there must be a file
called index.theme that describes the theme. The first index.theme
found while searching the base directories in order is used. This
file describes the general attributes of the theme.
</para>
<para>
In the theme directory are also a set of subdirectories containing
image files. Each directory contains icons designed for a certain
nominal icon size, as described by the index.theme file. The
subdirectories are allowed to be several levels deep, e.g. the
subdirectory "48x48/apps" in the theme "hicolor" would end up at
$basedir/hicolor/48x48/apps.
</para>
<para>
The image files must be one of the types: PNG, XPM, or SVG, and
the extension must be ".png", ".xpm", or ".svg" (lower case). The
support for SVG files is optional. Implementations that do not
support SVGs should just ignore any ".svg" files. In
addition to this there may be an additional file with extra
icon-data for each file. It should have the same basename as the
image file, with the extension ".icon". e.g. if the icon file is
called "mime_source_c.png" the corresponding file would be named
"mime_source_c.icon".
</para>
</sect1>
<sect1 id="file_formats">
<title>File Formats</title>
<para>
Both the icon theme description file and the icon data files are
ini-style text files, as described in the desktop file
specification. They don't have any encoding field. Instead, they
must always be stored in UTF-8 encoding.
</para>
<para>
The index.theme file must start with a section called <citetitle>Icon
Theme</citetitle>, with contents according to table 1 below. All lists are
comma-separated.

<title>Icon Lookup</title>
<para>
The icon lookup mechanism has two global settings, the list of
base directories and the internal name of the current theme. Given
these we need to specify how to look up an icon file from the icon
name and the nominal size.
</para>
<para>
The lookup is done first in the current theme, and then
recursively in each of the current theme's parents, and
finally in the default theme called "hicolor" (implementations may
add more default themes before "hicolor", but "hicolor" must be
last). As soon as there is an icon of any size that matches in a
theme, the search is stopped. Even if there may be an icon with a
size closer to the correct one in an inherited theme, we don't want
to use it. Doing so may generate an inconsistant change in an icon
when you change icon sizes (e.g. zoom in).
</para>
<para>
The lookup inside a theme is done in three phases. First all the
directories are scanned for an exact match, e.g. one where the
allowed size of the icon files match what was looked up. Then all
the directories are scanned for any icon that matches the name. If
that fails we finally fall back on unthemed icons. If we fail to
find any icon at all it is up to the application to pick a good
fallback, as the correct choice depends on the context.
</para>
<para>
The exact algorithm (in pseudocode) for looking up an icon in a theme
(if the implementation supports SVG) is:
<programlisting>
FindIcon(icon, size) {
filename = FindIconHelper(icon, size, user selected theme);
if filename != none
return filename
filename = FindIconHelper(icon, size, "hicolor");
if filename != none
return filename
return LookupFallbackIcon (icon)
}
FindIconHelper(icon, size, theme) {
filename = LookupIcon (icon, size, theme)
if filename != none
return filename
if theme has parents
parents = theme.parents
for parent in parents {
filename = FindIconHelper (icon, size, parent)
if filename != none
return filename
}
return none
}
</programlisting>
With the following helper functions:
<programlisting>
LookupIcon (iconname, size, theme) {
for each subdir in $(theme subdir list) {
for each directory in $(basename list) {
for extension in ("png", "svg", "xpm") {
if DirectoryMatchesSize(subdir, size) {
filename = directory/$(themename)/subdir/iconname.extension
if exist filename
return filename
}
}
}
}
minimal_size = MAXINT
for each subdir in $(theme subdir list) {
for each directory in $(basename list) {
for extension in ("png", "svg", "xpm") {
filename = directory/$(themename)/subdir/iconname.extension
if exist filename and DirectorySizeDistance(subdir, size) < minimal_size {
closest_filename = filename
minimal_size = DirectorySizeDistance(subdir, size)
}
}
}
}
if closest_filename set
return closest_filename
return none
}
LookupFallbackIcon (iconname) {
for each directory in $(basename list) {
for extension in ("png", "svg", "xpm") {
if exists directory/iconname.extension
return directory/iconname.extension
}
}
return none
}
DirectoryMatchesSize(subdir, iconsize) {
read Type and size data from subdir
if Type is Fixed
return Size == iconsize
if Type is Scaled
return MinSize <= iconsize <= MaxSize
if Type is Threshold
return Size - Threshold <= iconsize <= Size + Threshold
}
DirectorySizeDistance(subdir, size) {
read Type and size data from subdir
if Type is Fixed
return abs(Size - iconsize)
if Type is Scaled
if iconsize < MinSize
return MinSize - iconsize
if iconsize > MaxSize
return iconsize - MaxSize
return 0
if Type is Threshold
if iconsize < Size - Threshold
return MinSize - iconsize
if iconsize > Size + Threshold
return iconsize - MaxSize
return 0
}
</programlisting>
</para>
<para>
In some cases you don't always want to fall back to an icon in an
inherited theme. For instance, sometimes you look for a set of
icons, prefering any of them before using an icon from an inherited
theme. To support such operations implementations can contain a
function that finds the first of a list of icon names in the inheritance
hierarchy. I.E. It would look something like this:
<programlisting>
FindBestIcon(iconList, size) {
filename = FindBestIconHelper(iconList, size, user selected theme);
if filename != none
return filename
filename = FindBestIconHelper(iconList, size, "hicolor");
if filename != none
return filename
for icon in iconList {
filename = LookupFallbackIcon (icon)
if filename != none
return filename
}
return none;
}
FindBestIconHelper(iconList, size, theme) {
for icon in iconList {
filename = LookupIcon (icon, size, theme)
if filename != none
return filename
}
if theme has parents
parents = theme.parents
for parent in parents {
filename = FindBestIconHelper (iconList, size, parent)
if filename != none
return filename
}
return none
}
</programlisting>
This can be very useful for example when handling mimetype icons, where there
are more and less "specific" versions of icons.
</para>

Here is an example index.theme file:
<programlisting>[Icon Theme]

The corresponding directory tree in the /usr/share/icons
directory could look like this:
<programlisting>birch/index.theme
birch/scalable/apps/mozilla.svg
birch/scalable/mimetypes/mime_text_plain.svg
birch/scalable/mimetypes/mime_text_plain.icon
birch/48x48/apps/mozilla.png
birch/32x32/apps/mozilla.png
birch/48x48/mimetypes/mime_text_plain.png
birch/48x48/mimetypes/mime_text_plain.icon</programlisting>
Where birch/scalable/mimetypes/mime_text_plain.icon contains:
<programlisting>[Icon Data]
DisplayName=Mime text/plain
EmbeddedTextRectangle=100,100,900,900
AttachPoints=200,200|800,200|500,500|200,800|800,800</programlisting>
And birch/48x48/mimetypes/mime_text_plain.icon contains:
<programlisting>[Icon Data]
DisplayName=Mime text/plain
EmbeddedTextRectangle=8,8,40,40
AttachPoints=20,20|40,40|50,10|10,50</programlisting>

In this example a lookup of "mozilla" would get the prerendered
48x48 and 32x32 icons before the SVG icons due to the order of
Directories.

<title>Installing Application Icons</title>
<para>
So, you're an application author, and want to install application icons
so that they work in the KDE and Gnome menus. Minimally you should install
a 48x48 icon in the hicolor theme. This means installing a PNG file in
$prefix/share/icons/hicolor/48x48/apps. Optionally you can install icons in different
sizes. For example, installing a svg icon in $prefix/share/icons/hicolor/scalable/apps
means most desktops will have one icon that works for all sizes. You might even want to
install icons with a look that matches other well known themes so your application
will fit in with some specific desktop environment.
</para>
<para>
It is recommended that the icons installed in the hicolor theme look neutral,
since it is a fallback theme that will be used in combination with some very
different looking themes. But if you don't have any neutral icon, please install
whatever icon you have in the hicolor theme so that all applications get at
least some icon in all themes.

<sect1 id="implementation_notes">
<title>Implementation Notes</title>
<para>
The algorithm as described in this document works by always
looking up filenames in directories (a stat in unix
terminology). A good implementation is expected to read the
directories once, and do all lookups in memory using that
information.
</para>
<para>
This caching can make it impossible for users to add icons without
having to restart applications. In order to handle this, any
implementation that does caching is required to look at the mtime
of the toplevel icon directories when doing a cache lookup, unless
it already did so less than 5 seconds ago. This means that any
icon editor or theme installation program need only to change the
mtime of the the toplevel directory where it changed the theme to
make sure that the new icons will eventually get used.

The icon theme specification is based on the original
KDE icon theme system designed by Antonio Larossa,
Geert Janssen and Torsten Rahn. The common specification
mostly adds support for .icon files, renames the icon theme
description files and removes a few references to kde in them.
