Icon Repository for the Applications

All of the icons, separated by themes are included in this directory. These icons are built into .zip files, and re-ordered / packed for efficiency reasons based on our UI configuration by the postprocess/CustomTarget_images.mk.

An icon theme does not need to contain all images, since these can be layered one on top of another.

In general the layering is done like this:

<leaf theme>
breeze
colibre

Icon naming convention

sc* icons are 16x16 px (small) lc* icons are 24x24 px (large) There is also an 32px folder at cmd/ with 32 px icons

16x16 px icons are used in the menus 24x24 px icons are used in toolbars and sidebar Notebook bar use 24x24 px icons when there is only one icon, and 16x16 px everywhere else

sc and lc icon are followed by the .uno:CommandName (see below)

How to Add a New Image Set

Create a directory for it here (let’s call it e.g. new_set)

FIXME: It is important to use an underscore _ to delimit more words. scp2 compilation crashes when using a dash -. It evidently splits the name into two strings.
- It’s probably not true anymore with filelists.
- if this gets changed, IconThemeSelector::SetPreferredIconTheme needs to change too
Add its name (new_set) to WITH_THEMES variable in configure.ac
The fallback for particular icons is defined be packimages_CUSTOM_FALLBACK_1 in packimages/CustomTarget_images.mk

How to Add a New Icon for a New Command

Assume you defined a dispatch command in officecfg like the following:

in officecfg/registry/data/org/openoffice/Office/UI/CalcCommands.xcu

<node oor:name=".uno:OpenFromCalc" oor:op="replace">
    <prop oor:name="Label" oor:type="xs:string">
        <value xml:lang="en-US">~Open...</value>
    </prop>
    <prop oor:name="Properties" oor:type="xs:int">
        <value>1</value>
    </prop>
</node>

Here, you need to define a property named “Properties”, with its value set to 1 so that the icons show up.

Now, you need to add 2 new icon images under icon-themes/colibre/cmd/, one for the large size and one for the smaller size. The name of each image must be lc_<command name>.png and sc_<command name>.png. Here, the command name is the name given in the above .xcu file without the .uno: prefix and all its letters lower-cased. In this example, the file names will be lc_openfromcalc.png and sc_openfromcalc.png. Note that you need to add new images to the colibre theme for them to show up in any themes at all.

8 bit palettes are on the slow path for quartz/svp/gtk3 so avoid using palettes with…

$ optipng -nc <file>
