JPEG importer plugin.
Supports RGB or grayscale images with 8 bits per channel. The images are imported with PixelFormat::
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::
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
find_package(MagnumPlugins REQUIRED JpegImporter) # ... target_link_libraries(your-app PRIVATE MagnumPlugins::JpegImporter)
While some systems (such as macOS) still ship only with the vanilla libJPEG, you can get a much better decoding performance by using libjpeg-turbo.
