15. Icon handling

15.1 Generic

The window manager expects to find two XPM files for each icon specified in the configuration files as ICON. They should be named like this:

ICON_16x16.xpm

A small 16x16 pixmap.

ICON_32x32.xpm

A normal 32x32 pixmap.

ICON_48x48.xpm

A large 48x48 pixmap.

Other pixmap sizes like 20x20, 24x24, 40x40, 48x48, 64x64 might be used in the future. Perhaps we need a file format that can contain more than one image (with different sizes and color depths) like Windows'95 and OS/2 .ICO files.

It would be nice to have a feature from OS/2 that varies the icon size with screen resolution (16x16 and 32x32 icons are quite small on 4000x4000 screens ;-)

15.2 Imlib

When compiled with the Imlib image library all of Imlib's image formats (bmp, jpeg, ppm, tiff, gif, png, ps, xpm on my machine) are supported. Use them by specifying the full filename or an absolute path:

ICON.bmp,

A PPM icon in your IconPath.

/usr/share/pixmap/ICON.png

An PNG image with absolute location.
