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 PostScript 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 associate 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.
