PNG image converter plugin.
Creates Portable Network Graphics (
*.png) files from images with format PixelFormat::
This plugin depends on the Trade and libPNG libraries and is built if
MAGNUM_WITH_PNGIMAGECONVERTER is enabled when building Magnum Plugins. To use as a dynamic plugin, load
"PngImageConverter" via Corrade::
Additionally, if you're using Magnum as a CMake subproject, bundle the magnum-plugins repository and do the following. Using libPNG 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_PNGIMAGECONVERTER ON CACHE BOOL "" FORCE) add_subdirectory(magnum-plugins EXCLUDE_FROM_ALL) # So the dynamically loaded plugin gets built implicitly add_dependencies(your-app MagnumPlugins::PngImageConverter)
To use as a static plugin or as a dependency of another plugin with CMake, put FindMagnumPlugins.cmake into your
modules/ directory, request the
PngImageConverter component of the
MagnumPlugins package and link to the
find_package(MagnumPlugins REQUIRED PngImageConverter) # ... target_link_libraries(your-app PRIVATE MagnumPlugins::PngImageConverter)
The PNG file format doesn't have a way to distinguish between 2D and 1D array images. If an image has ImageFlag2D::
- class AbstractImageConverter
