Magnum::Trade::JpegImporter class

#include <MagnumPlugins/JpegImporter/JpegImporter.h>

Usage

This plugin depends on the Trade and libJPEG libraries and is built if MAGNUM_WITH_JPEGIMPORTER is enabled when building Magnum Plugins. To use as a dynamic plugin, load "JpegImporter" via Corrade::PluginManager::Manager.

Additionally, if you're using Magnum as a CMake subproject, bundle the magnum-plugins repository and do the following. Using libJPEG itself as a CMake subproject isn't tested at the moment, so you need to provide it as a system dependency and point CMAKE_PREFIX_PATH to its installation dir if necessary.

set(MAGNUM_WITH_JPEGIMPORTER ON CACHE BOOL "" FORCE)
add_subdirectory(magnum-plugins EXCLUDE_FROM_ALL)

# So the dynamically loaded plugin gets built implicitly
add_dependencies(your-app MagnumPlugins::JpegImporter)

To use as a static plugin or as a dependency of another plugin with CMake, put FindMagnumPlugins.cmake into your modules/ directory, request the JpegImporter component of the MagnumPlugins package and link to the MagnumPlugins::JpegImporter target:

find_package(MagnumPlugins REQUIRED JpegImporter)

# ...
target_link_libraries(your-app PRIVATE MagnumPlugins::JpegImporter)
