Detailed Description

Implementation of the PixelCanvas for PostScript devices.

Prerequisite

1. PixelCanvas
2. PSPixelCanvasColorTable
3. PSDriver

Intended use:

Public interface

Etymology

PSPixelCanvas is a mechanism for drawing on paper.

Motivation

Synopsis

PSPixelCanvas implements PixelCanvas for PostScript output. See Example for example usage.

Example

1. Create an output stream.
2. Create a PSDriver choosing a page type (letter, A4, etc.). (PSDriver can take a filename as an argument instead of an ostream). See: PSDriver for more on creating PSDrivers..
3. Create PSPixelCanvasColorTable
4. Create PSPixelCanvas
5. Draw something pretty.
6. Delete everything and close the stream.
   Tip: Neither PSPixelCanvasColorTable nor PSPixelCanvas delete their PSDriver;
   

 PSDriver *psd = new PSDriver("test.ps", PSDriver::LETTER);
 PSPixelCanvasColorTable *pscct = new PSPixelCanvasColorTable(psd);
 PSPixelCanvas psc = new PSPixelCanvas(psd, pscct);
... (a miracle happens).
 delete psc;
 delete pscct;
 delete psd;

Tip: Since PostScript does not deal in in pixels, PSPixelCanvas assumes an adjustable number of pixels per inch; (Currently 1200dpi); Use the setResolution function to change this if the calling progam can't handle a 128M pixel display;

To Do

1. Lots of 'get' functions. Some don't make sense for PostScript. Others haven't been done yet.
2. Events.
3. Partial support for X11 color names is hacked in. Doing it 'correctly' would require changing the constructors.
4. No display list support.
5. Foreground/background/clear color support is in. However, these and many other routines don't really support RGB mode yet.
6. See: PSDriver for another list.
