 The MagickWand API is the recommended interface between the C programming

 MagickCore C API, MagickWand uses only a few opaque types. Accessors are
 available to set or get important wand properties.

 This package includes header files needed to compile
 programs using MagickWand.

 This package is independent of channel depth.
