Describes the image formats supported by ImageMagick. If the optional block is present, calls the block once for each image format. The first argument, k, is the format name. The second argument, v, is the properties string described below.

B is “*” if the format has native blob support, or “ ” otherwise.
R is “r” if ImageMagick can read that format, or “-” otherwise.
W is “w” if ImageMagick can write that format, or “-” otherwise.
A is “+” if the format supports multi-image files, or “-” otherwise.
