NAME
       RasterComp, RasterView, PSRaster - raster component subject, view, and PostScript external
       representation

SYNOPSIS
       #include <Unidraw/Components/rastercomp.h>

DESCRIPTION
       RasterComp is a GraphicComp that represents a raster image.  It uses a RasterRect graphic
       to store its graphical attributes.  RasterView is a GraphicView for displaying the raster
       image.  PSRaster is a PostScriptView that externalizes the subject's information in Post‐
       Script form.

RASTERCOMP PUBLIC OPERATIONS
       RasterComp(RasterRect* = nil, const char* filename = nil)
              The constructor takes an optional RasterRect structured graphic that defines the
              attributes of the raster image.  You can also supply an optional file name to asso‐
              ciate the component with a file containing the (copious) image data.

       RasterRect* GetRasterRect()
              Return the RasterRect graphic that defines the raster's attributes.  GetRaster is
              simply a more specific form of the GetGraphic operation.

       const char* GetFileName()
              Return the file name specified in the constructor, if any.

RASTERVIEW PUBLIC OPERATIONS
       RasterView(RasterComp* = nil)
              Create an RasterView, optionally supplying the subject.

       RasterComp* GetRasterComp()
              Return the subject.

PSRASTER PUBLIC OPERATIONS
       PSRaster(RasterComp* = nil)
              Construct a PostScript external representation of the given subject, if any.
