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.
