OpenEXR image converter plugin using miniexr.
This plugins provides the
OpenExrImageConverter plugin, but note that this plugin generates only uncompressed files and the performance might be worse than when using a plugin dedicated for given format, i.e. OpenExrImageConverter.
This plugin depends on the Trade library and is built if
MAGNUM_WITH_MINIEXRIMAGECONVERTER is enabled when building Magnum Plugins. To use as a dynamic plugin, load
"MiniExrImageConverter" via Corrade::
Additionally, if you're using Magnum as a CMake subproject, bundle the magnum-plugins repository and do the following:
set(MAGNUM_WITH_MINIEXRIMAGECONVERTER ON CACHE BOOL "" FORCE) add_subdirectory(magnum-plugins EXCLUDE_FROM_ALL) # So the dynamically loaded plugin gets built implicitly add_dependencies(your-app MagnumPlugins::MiniExrImageConverter)
To use as a static plugin or as a dependency of another plugin with CMake, put FindMagnumPlugins.cmake into your
modules/ directory, request the
MiniExrImageConverter component of the
MagnumPlugins package and link to the
find_package(MagnumPlugins REQUIRED MiniExrImageConverter) # ... target_link_libraries(your-app PRIVATE MagnumPlugins::MiniExrImageConverter)
The output is always uncompressed, only half-float RGB and RGBA is supported.
The OpenEXR file format doesn't have a way to distinguish between 2D and 1D array images. If an image has ImageFlag2D::
As OpenEXR doesn't have a registered MIME type, mimeType() returns
- class AbstractImageConverter
- Base for image converter plugins.
