low-level image manipulation library -- quantum depth Q16

 The MagickCore API is a low-level interface between the C programming language
 and the ImageMagick image processing libraries and is recommended for
 wizard-level programmers only. Unlike the MagickWand C API which uses only a
 few opaque types and accessors, with MagickCore you almost exclusively access
 the structure members directly.
 .
 This package contains the C libraries needed to run executables that make
 use of MagickCore.
 .
 This version of libmagickcore is compiled for a channel
 depth of 16 bits (Q16).
