ICO or PNG Format?

  • 772

Kind of a dumb question, but which file format are ubuntu icons (in apps and dash to dock) are they .png or .ico files? I want to create some icon/themes for ubuntu. But I'm not sure which format to use, also is 256x256 the resolution like in windows?

Thanks in advance :)

format icons files png

    Icons in Ubuntu

    Fixed size icons are usually in png format (can be viewed with most image viewers).

    Scalable icons are usually in svg format (can be viewed with for example eog, Eye of Gnome, and can be created and manipulated (and zoomed) with inkscape).

    You can find icons that belong to the desktop environment and the installed application programs in subdirectories of

    /usr/share/icons/

    You will find a whole series of resolutions. In my Lubuntu the following commands find resolutions from 8x8 to 512x512. And there are scalable icons, which will be displayed well in any size/resolution (not pixelated).

    $ cd /usr/share/icons/hicolor

$ ls|sort -n
icon-theme.cache
index.theme
