Typedef Documentation

typedef struct a_file_image FileImage
 

typedef struct a_image Image
 

An image family is like a Mac Finder icon family, but allows multiple kinds of images of an arbitrary set of sizes. Individual images in a family may have both "lisp" form and "raw" form, the former being used for reading and writing, while the raw form is an intermediary for conversion to and from platform-specific representations.
