16 [s9;%% Raster is an abstract class representing raster image. Example
17 of Raster derived classes is PngRaster, that serves as .png image
20 [s9;%% Raster provides basic information about image (GetSize and
21 GetInfo returning Raster`::Info) and is a source of image scanlines.
22 Scanlines are returned as Raster`::Line objects. If possible,
23 Raster derived classes should attempt to minimize memory requirements.
