DESCRIPTION

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 xloadimage program to display the image file. This will display images from the directories given in the "path" section of the .xloadimagerc file.

This also depends on xwininfo to get information about the root window.

The Name

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.

OPTIONS

Boolean options can be disabled by prefixing them with 'no'; for example, --notile will turn off tiling of the image.

--centre | --center

Centre the image on the root window.

--colours num | --colors num

Limit the number of colours used to display the image. This is useful for a 256-colour display.

--config_dir directory

Alternative directory in which to look for muralis config files. Note that muralis will still look for the xloadimage config file at "~/.xloadimagerc".

--exclude string

If an image matches this, it is excluded from --random, --list, or --nth display.

--is_image string

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.

--fullscreen

The image will be zoomed to fit the size of the screen.

--help

Print help message and exit.

--list

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)

--listformat format

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.

--manpage

Print the full help documentation (manual page) and exit. This will only work if you have perldoc installed.

--match string

If using the --list or --random options, limit the image(s) to those which match the string.

--nth num

Display the nth image. If --match is given, limit the selection to images which match the match-string.

--outfile

Output file for the --list command to print its output. If this argument is not given, list will list to standard output.

--random

Pick a random image to display. If --match is given, limit the selection to images which match the match-string.

--repeat_last

Display the last image which was displayed. This is useful to re-display an image while overriding the default display options.

--rotate degrees

Rotate the image by 90, 180 or 270 degrees.

--smooth

Smooth the image (useful if the image has been zoomed).

--tile

Tile the image to fill the root window.

--unseen

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 .xloadimagerc file, you will need to delete the 'unseen' file in order to reset the list of unseen images.

--verbose

Print informational messages.

--version

Print version information and exit.

--zoom percent

Enlarge or reduce the size of the image by the given percent.

ENVIRONMENT

HOME

muralis looks in the HOME directory for config files.

FILES

${HOME}/.xloadimagerc

muralis uses the "path" section of this file to determine what directories to look in for image files.

Configuration files for muralis are placed in the $HOME/.muralis directory (which is created if it doesn't exist).

~/.muralis/last

The name of the most recently displayed image.

~/.muralis/unseen

Contains a list of unseen image files.

REQUIRES

Getopt::Long
