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


       image - Create and manipulate images

       image option ?arg arg ...?

       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	redis‐
	      play 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 exist‐
	      ing instances will use the new image.

       image height name
	      Returns a decimal string giving the height of image name in pix‐

       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 argu‐
	      ment to image create).

       image width name
	      Returns a decimal string giving the width of image name in  pix‐

       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 back‐
	      ground color, or nothing.	 See the bitmap manual entry for  more

       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.
