Magnum::DebugTools::CompareImageToFile class
#include <Magnum/DebugTools/CompareImage.h>

Image-to-file comparator for Corrade::TestSuite.

A combination of CompareImage and CompareImageFile, which allows to compare an in-memory image to a image file. See their documentation for more information. Example usage:

Image2D actual = doProcessing();
CORRADE_COMPARE_WITH(actual, "expected.png",
    (DebugTools::CompareImageToFile{1.5f, 0.01f}));
