Creating an image

Before you can display a graphic in Tk, you must first create a Tk image. To accomplish this, Tk provides the image command. This command allows you to create, delete, and query the keywords for any of the supported image types. The built-in image types are bitmap (two color graphics) and photo. The photo types as shipped in the base distribution are PPM/PGM and GIF.

Based on the keyword used the image command takes several syntactic forms. The syntax and keywords are as follows:

image keyword path

Keyword	Interpretation
create	Creates an image and a command with the same name.
delete	Deletes the named image.
height	Returns a decimal string containing the height of the image in pixels.
inuse	Returns a Boolean value indicating if the named image provided is currently in use.
names	Returns a list containing the names of all created images.
type	Returns the type of image as referenced by name.
