- Find newer additions such as animate, compare, etc. - Find development api: Magick++, MagickCore, MagickWand - Use FindPackageHandleStandardArgs to output standard messages.

# - Find Image Magick
|
||||
# This module finds if ImageMagick tools are installed and determines
|
||||
# where the executables are. This code sets the following variables:
|
||||
# - Find the ImageMagick binary suite.
|
||||
# This module will search for a set of ImageMagick tools specified
|
||||
# as components in the FIND_PACKAGE call. Typical components include,
|
||||
# but are not limited to (future versions of ImageMagick might have
|
||||
# additional components not listed here):
|
||||
#
|
||||
# IMAGEMAGICK_CONVERT_EXECUTABLE =
|
||||
# the full path to the 'convert' utility
|
||||
# IMAGEMAGICK_MOGRIFY_EXECUTABLE =
|
||||
# the full path to the 'mogrify' utility
|
||||
# IMAGEMAGICK_IMPORT_EXECUTABLE =
|
||||
# the full path to the 'import' utility
|
||||
# IMAGEMAGICK_MONTAGE_EXECUTABLE =
|
||||
# the full path to the 'montage' utility
|
||||
# IMAGEMAGICK_COMPOSITE_EXECUTABLE =
|
||||
# the full path to the 'composite' utility
|
||||
# animate
|
||||
# compare
|
||||
# composite
|
||||
# conjure
|
||||
# convert
|
||||
# display
|
||||
# identify
|
||||
# import
|
||||
# mogrify
|
||||
# montage
|
||||
# stream
|
||||
#
|
||||
# If no component is specified in the FIND_PACKAGE call, then it only
|
||||
# searches for the ImageMagick executable directory. This code defines
|
||||
# the following variables:
|
||||
#
|
||||
# ImageMagick_FOUND - TRUE if all components are found.
|
||||
# ImageMagick_EXECUTABLE_DIR - Full path to executables directory.
|
||||
# ImageMagick_<component>_FOUND - TRUE if <component> is found.
|
||||
# ImageMagick_<component>_EXECUTABLE - Full path to <component> executable.
|
||||
#
|
||||
# There are also components for the following ImageMagick APIs:
|
||||
#
|
||||
# Magick++
|
||||
# MagickWand
|
||||
# Magick
|
||||
#
|
||||
# For these components the following variables are set:
|
||||
#
|
||||
# ImageMagick_FOUND - TRUE if all components are found.
|
||||
# ImageMagick_INCLUDE_DIRS - Full paths to all include dirs.
|
||||
# ImageMagick_LIBRARIES - Full paths to all libraries.
|
||||
# ImageMagick_<component>_FOUND - TRUE if <component> is found.
|
||||
# ImageMagick_<component>_INCLUDE_DIRS - Full path to <component> include dirs.
|
||||
# ImageMagick_<component>_LIBRARIES - Full path to <component> libraries.
|
||||
#
|
||||
# Example Usages:
|
||||
# FIND_PACKAGE(ImageMagick)
|
||||
# FIND_PACKAGE(ImageMagick COMPONENTS convert)
|
||||
# FIND_PACKAGE(ImageMagick COMPONENTS convert mogrify display)
|
||||
# FIND_PACKAGE(ImageMagick COMPONENTS Magick++)
|
||||
# FIND_PACKAGE(ImageMagick COMPONENTS Magick++ convert)
|
||||
#
|
||||
# Note that the standard FIND_PACKAGE features are supported
|
||||
# (i.e., QUIET, REQUIRED, etc.).
