The width of the images in this image list.
The height of the images in this image list.
A list of images or image sets.
The :image-sets initarg specifies a list. Each item in the list may be one of the following.
This specifies the filename of a file suitable for loading with gp:load-image . Currently this must be a BMP file.
The symbol must have been previously registered by means of a call to gp:register-image-translation .
An image object, as returned by gp:load-image .
See image-set for further details.
Note that image sets are added in their entirety; it is not possible to use image-locators to extract a single image from an image set.
The images added to the image list are numbered in order, starting from zero. An image-set containing n images contributes n images to the image list, and hence consumes n consecutive integer indices.
