OpenJDK 1.22 · sun.awt.image.ImagingLib

This class provides a hook to access platform-specific imaging code. If the implementing class cannot handle the op, tile format or image format, the method will return null; If there is an error when processing the data, the implementing class may either return null (in which case our java code will be executed) or may throw an exception.
