defimage

defimage is an autoloaded Lisp macro in `image.el'.

(defimage SYMBOL SPECS &optional DOC)

Define SYMBOL as an image, and return SYMBOL.

SPECS is a list of image specifications. DOC is an optional
documentation string.

Each image specification in SPECS is a property list. The contents of
a specification are image type dependent. All specifications must at
least contain the properties `:type TYPE' and either `:file FILE' or
`:data DATA', where TYPE is a symbol specifying the image type,
e.g. `xbm', FILE is the file to load the image from, and DATA is a
string containing the actual image data. The first image
specification whose TYPE is supported, and FILE exists, is used to
define SYMBOL.

Example:

(defimage test-image ((:type xpm :file "~/test1.xpm")
(:type xbm :file "~/test1.xbm")))
