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.
