libmagickcore-6.q16hdri-dev 8:6.9.10.23+dfsg-2.1ubuntu11.6 (armhf binary) in ubuntu focal

 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 includes header static libraries needed to compile
 programs using MagickCore.
 .
 This version of libmagickcore-dev is compiled for a channel
 depth of 16 bits with high dynamic range (Q16HDRI).
