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 redisplay with the new
image delete name
Deletes the image named name and returns an empty string. If there
are instances of the image displayed in widgets, the image 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
image height name
Returns a decimal string giving the height of image name in pixels.
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).
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.
The following image types are defined by Tk so they will be available in
any Tk application. Individual applications or extensions may define
Each pixel in the image displays a foreground color, a background
color, or nothing. See the bitmap manual entry for more
Displays a variety of full-color images, using dithering to
approximate colors on displays with limited color capabilities. See
