NAME

       gkrellkam-list - format of the list description files used by GKrellKam

DESCRIPTION

       GKrellKam  lists  describe  a  series  of  image sources, used in order or at random by the GKrellKam plugin. Online lists (downloadable by
       GKrellKam with HTTP) use this same syntax.

       Blank lines and comments (beginning with '#') in GKrellKam lists are ignored. Every line of text that does not begin with a  tab  character
       is considered an image source.

       An image source can be one of several types:

       image  Sources of type image consist of a complete local filename to an image file.

       url    Type url is just that; a ftp:// or http:// URL pointing at an online image file.

       script Type  script  is	a  system command, executed in a shell by GKrellKam when it's time to get this image. The output of the command is
	      assumed to be a complete filename of a local image file, optionally terminated with newlines/whitespace. The corresponding image	is
	      loaded.

       list   Type list causes a different GKrellKam list to be included in the current one.

       Each image source line should look like this:

	      type: name

       The  "type:  "  part of the line can be omitted for images and URLs, to make these list files backwards compatible with earlier versions of
       GKrellKam, but it is suggested that you specify them. It will enhance the readability of the list file.

       There are also properties that can be applied to types image, url, and script. Properties must follow the image source line that they  mod-
       ify, and must begin with a tab character. These include:

       tooltip
	      This  sets  the  message	shown  when the mouse is kept over the image panel in GKrellKam for a few seconds. If not set, the image's
	      filename or URL is shown instead.

       seconds
	      This changes the number of seconds that an image will remain displayed.  If not set, the "Default number of seconds"  set  for  that
	      panel in the GKrellM configuration window will be used.

       refresh
	      If  set,	this  sets  the  minimum length of time that must elapse before the image is re-loaded. If the image cycles up before that
	      time, the old image will be used. For script types, this means that the script will not be re-run. For url types, the image will not
	      be  fetched using wget. When this property is not set, url images will be downloaded every time they are displayed, and scripts will
	      be run every time.

EXAMPLE

       This is a simple example of a GKrellKam list. For a better example, see example.list from this distribution.

	      # .krellkam.list
	      # This list rotates through ~/pics/mypic[1-4].jpg along with a
	      # webcam, and then displays the pictures in ~/lists/sub.list

	      image: /home/paul/pics/mypic1.jpg
	      /home/paul/pics/mypic2.jpg
	      image: /home/paul/pics/mypic3.jpg
	      http://www.usu.edu/webcam/fullsize.jpg
	      [tab] tooltip: This is the building where I work

	      image: /home/paul/pics/mypic4.jpg
	      [tab] seconds: 4
	      [tab] tooltip: Don't display this one very long

	      list: /home/paul/lists/sub.list

NAME

       image - Create and manipulate images

SYNOPSIS

       image option ?arg arg ...?
_________________________________________________________________

DESCRIPTION

       The image command is used to create, delete, and query images.  It can take several different forms, depending on the option argument.  The
       legal forms are:

       image create type ?name? ?option value ...?
	      Creates a new image and returns its name.  type specifies the type of the image, which must be one of the  types	currently  defined
	      (e.g.,  bitmap).	 name  specifies  the name for the image;  if it is omitted then Tk picks a name of the form imagex, where x is an
	      integer.	There may be any number of option-value pairs, which provide configuration options for the new image.  The  legal  set	of
	      options  is  defined  separately	for  each image type;  see below for details on the options for built-in image types.  If an image
	      already exists by the given name then it is replaced with the new image and any instances of that image will redisplay with the  new
	      contents.  It is important to note that the image command will silently overwrite any procedure that may currently be defined by the
	      given name, so choose the name wisely.  It is  recommended  to  use  a  separate	namespace  for	image  names  (e.g.,  ::img::logo,
	      ::img::large).

       image delete ?name name ...?
	      Deletes each of the named images and returns an empty string.  If there are instances of the images displayed in widgets, the images
	      won't actually be deleted until all of the instances are released.  However, the association between the	instances  and	the  image
	      manager  will be dropped.  Existing instances will retain their sizes but redisplay as empty areas.  If a deleted image is recreated
	      with another call to image create, the existing instances will use the new image.

       image height name
	      Returns a decimal string giving the height of image name in pixels.

       image names
	      Returns a list containing the names of all existing images.

       image type name
	      Returns the type of image name (the value of the type argument to image create when the image was created).

       image types
	      Returns a list whose elements are all of the valid image types (i.e., all of the values that may be supplied for the  type  argument
	      to image create).

       image width name
	      Returns a decimal string giving the width of image name in pixels.

BUILT-IN IMAGE TYPES
       The  following  image  types  are defined by Tk so they will be available in any Tk application.  Individual applications or extensions may
       define additional types.

       bitmap Each pixel in the image displays a foreground color, a background color, or nothing.  See the bitmap manual entry for more  informa-
	      tion.

       photo  Displays a variety of full-color images, using dithering to approximate colors on displays with limited color capabilities.  See the
	      photo manual entry for more information.
