.SH SYNOPSIS
.B #include <Unidraw/Components/rastercomp.h>
.SH 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
PostScript form.
.SH RASTERCOMP PUBLIC OPERATIONS
.TP
.B "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 associate the component with a file containing
the (copious) image data.
.TP
.B "RasterRect* GetRasterRect()"
Return the RasterRect graphic that defines the raster's attributes.
GetRaster is simply a more specific form of the GetGraphic operation.
.TP
.B "const char* GetFileName()"
Return the file name specified in the constructor, if any.
.SH RASTERVIEW PUBLIC OPERATIONS
.TP
.B "RasterView(RasterComp* = nil)"
Create an RasterView, optionally supplying the subject.
.TP
.B "RasterComp* GetRasterComp()"
Return the subject.
.SH PSRASTER PUBLIC OPERATIONS
.TP
.B "PSRaster(RasterComp* = nil)"
Construct a PostScript external representation of the given subject,
if any.
