class RasterDefaults:
You can use the RasterDefaults class to specify extra attributes used when creating a RasterImage object.
For example, you can use XResolution and YResolution to set the physical resolution (DPI) of all the RasterImage objects created afterwards.
You can use DitheringMethod to specify the default dithering method to use when converting an image from 64, 48, 32, 24, or 16 bits per pixel to 8 bits per pixel or fewer.
MemoryFlags and MemoryThreshold controls how newly created images use the system memory. The TemporaryDirectory controls where disk-based images are stored.
Use GetGlobalMemoryThresholds and SetGlobalMemoryThresholds to modify the conventional memory restrictions used when allocating new RasterImage objects.
