________________________________________________________________________________________________________________

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 a command with the same name 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 will not 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 inuse name
              Returns a boolean value indicating whether or not the image  given  by  name  is  in  use  by  any
              widgets.

       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.

       Additional  operations  (e.g.  writing  the image to a file) may be available as subcommands of the image
       instance command. See the manual page for the particular image type for details.

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 information.

       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.
