The muralis script displays a given image file on the desktop background (that is, the root window) of an X-windows display.
This tries to determine what size would best suit the image; whether to show it fullscreen or normal size, whether to show it tiled or centred on the screen. Setting the options overrides this behaviour.
One can also repeat the display of the last-displayed image, changing the display options as one desires.
This uses the an external program to display the image file; display backends are implemented as plugins. To find out which bckends are available, use the --backends option to print a list of them.
This also depends on xwininfo to get information about the root window.
The name "muralis" comes from the Latin "muralis" which is the word from which "mural" was derived. I just thought it was a cool name for a wallpaper script.
Boolean options can be disabled by prefixing them with 'no'; for example, --notile will turn off tiling of the image.
List which display backends are available. Note that this doesn't just check which plugin modules are installed, but also checks whether the program used by the backend is available.
Centre the image on the root window.
Limit the number of colours used to display the image. This is useful for a 256-colour display. Only supported by some backends.
Alternative directory in which to look for muralis config files.
Directory in which to look for image files. This can be repeated for more directories.
If an image matches this, it is excluded from --random, --list, or --nth display.
What files are considered to be image files? This is a regular expression checked against the filenames to see if they are image files. By default, muralis checks for commonly known image extensions, so that it doesn't try to display non-image files (such as text files) which might be in the image directories. Most of the time you don't need to use this option.
The image will be zoomed to fit the size of the screen, keeping the aspect ratio the same if the backend supports this.
Print help message and exit.
List all the images muralis knows about. If --match is given, this will restrict the list to those images matching the match-string. (see --listformat)
This defines the format used in the --list command. The format is either "normal" or "fullname". The normal format gives the directory names followed by the files in them. The "fullname" format gives just the full names of the files.
Print the full help documentation (manual page) and exit. This will only work if you have perldoc installed.
If using the --list or --random options, limit the image(s) to those which match the string.
Display the nth image. If --match is given, limit the selection to images which match the match-string.
An additional option or options to pass on to the backend. Used for uncommon options which are supported in one backend and not another.
Output file for the --list command to print its output. If this argument is not given, list will list to standard output.
What options will work for this backend?
Pick a random image to display. If --match is given, limit the selection to images which match the match-string.
Display the last image which was displayed. This is useful to re-display an image while overriding the default display options.
The image will be zoomed to fit the size of the screen. This does not preserve the aspect ratio. Some backends support both fullscreen and stretch, while some support only one or the other, in which case they are treated the same.
Tile the image to fill the root window.
When using the --rand or --nth option, this selects the images from a list of 'unseen' images. This can be used to cycle through your images without repeats. If this option is not used, then the --random option is truly random.
The 'unseen' list is in the '~/.muralis/unseen' file, which is automatically updated or created whenever the --unseen option is used. Note that if this file exists and the --unseen option is used, muralis does not check the image directories, so if you have added a new directory to your options, you will need to delete the 'unseen' file in order to reset the list of unseen images.
Which backend to use. See backends.
Print informational messages.
Print version information and exit.
Display on the given window, rather than the root window. This is useful for window-managers which take over the desktop display. Only works for backends which provide this option.
Enlarge or reduce the size of the image by the given percent.
muralis looks in the HOME directory for config files.
Configuration files for muralis are placed in the $HOME/.muralis directory (which is created if it doesn't exist).
Configuration file; contains command-line arguments in Getopt::ArgvFile format.
The name of the most recently displayed image.
Contains a list of unseen image files.
