       Tk::Image - Create and manipulate images


       $image = $widget->type(?arg arg ...?)

       $image->method(?arg arg ...?)


       The image constructors and methods are used to create, delete, and query images.  It can
       take several different forms, depending on the type.

       The constructors require a $widget to invoke them, this is used to locate a MainWindow.
       (This is because the underlying Tk code registers the images in the data structure for the

       The legal forms are:

       $widget->type?(?name?,?option=>value ...)?
           Creates a new image and returns an object.  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.

           Deletes the image $image 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 the same name) the existing
           instances will use the new image.

           Returns a decimal string giving the height of image name in pixels.

           Returns a boolean value indicating whether or not the image is in use by any widgets.

           Returns a list containing all existing images for $widget's MainWindow.

           Returns the type of  $image (the value of the type method 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 to create an image).

           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 additional types.

           Each pixel in the image displays a foreground color, a background color, or nothing.
           See Tk::Bitmap for more information.

           Pixmap is slightly more general than Bitmap, each pixel can be any available color or
           "transparent" (rendered as background color of the widget image is displayed in).
           Pixmap is best used for icons and other simple graphics with only a few colors.

           Pixmap is derived from Tix. See Tk::Pixmap for more information.

           Displays a variety of full-color images, using dithering to approximate colors on
           displays with limited color capabilities.  See Tk::Photo documentation for more


       It's necessary to use the "delete" method to delete an image object and free memory
       associated with it. Just using a lexical variable for storing the image object and letting
       the variable to go out of scope or setting to "undef" is not sufficient.
