image(n)	       Tk Built-In Commands		 image(n)

_________________________________________________________________

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.

       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 applica-
       tions 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.
