Photon Background Manager
The Photon Background Manager (bkgdmgr) provides advanced capabilities for Photon's desktop background display.
In addition to being able to draw a solid color background, bkgdmgr can blend primary and secondary colors in a tiled 8*8 pixel pattern, or display a bitmap image in any format that Photon supports. Bitmaps can be displayed in any of the following modes:
|If you need only a solid background color, you don't need to run bkgdmgr. The Photon Window Manager, pwm, can draw a solid color desktop background.|
The Background Manager reads options from a config file that it shares with pwm, located in $HOME/.ph/wm/wm.cfg. If $HOME isn't set, bkgdmgr looks for the file in /.ph/wm/wm.cfg. Normally you don't edit this file manually. Use the Background tab on the pwmopts utility to set the options for bkgdmgr, which are saved to the configuration file.
You can force bkgdmgr to reread the configuration file and reapply the settings by rerunning it, or by sending it the signal SIGUSR1, for example, slay -sUSR1 bkgdmgr.
