1mDESCRIPTION0m
       The  1mimage 22mcommand is used to create, delete, and query images.  It can
       take several different forms, depending on the  4moption24m  argument.   The
       legal forms are:

       1mimage create 4m22mtype24m ?4mname24m? ?4moption24m 4mvalue24m 4m...24m?
              Creates  a  new  image and returns its name.  4mtype24m specifies the
              type of the image, which must be  one  of  the  types  currently
              defined  (e.g., 1mbitmap22m).  4mname24m specifies the name for the image;
              if it is omitted then Tk picks a name of the form 1mimage4m22mx24m,  where
              4mx24m is an integer.  There may be any number of 4moption24m-4mvalue24m 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  redis-
              play  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., 1m::img::logo22m, 1m::img::large22m).

       1mimage delete 22m?4mname24m 4mname24m ...?
              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 1mimage create22m, the exist-
              ing instances will use the new image.

       1mimage height 4m22mname0m
              Returns a decimal string giving the height of image 4mname24m in pix-
              els.

       1mimage names0m
              Returns a list containing the names of all existing images.

       1mimage type 4m22mname0m
              Returns  the  type of image 4mname24m (the value of the 4mtype24m argument
              to 1mimage create 22mwhen the image was created).

       1mimage types0m
              Returns a list whose elements are all of the valid  image  types
              (i.e., all of the values that may be supplied for the 4mtype24m argu-
              ment to 1mimage create22m).

       1mimage width 4m22mname0m
              Returns a decimal string giving the width of image 4mname24m in  pix-
              els.


1mBUILT-IN IMAGE TYPES0m
       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.

       1mbitmap 22mEach  pixel  in  the  image displays a foreground color, a back-
              ground color, or nothing.  See the 1mbitmap 22mmanual entry for  more
              information.

       1mphoto  22mDisplays  a  variety  of  full-color  images, using dithering to
              approximate colors on displays with limited color  capabilities.
              See the 1mphoto 22mmanual entry for more information.
