Java Drawfile Renderer

Ever wanted to use Drawfiles on your Webpages. Well this is for you then. The Java Drawfile Renderer can display most Drawfiles or with a little alteration. All Object types are handled with the following restrictions :

• Fonts are mapped as follows:

  Acorn Font	Java Font

• Text Objects do not appear when using Acorn's Java 1.0.
• Dashed paths are not implemented.
• Path Objects may not appear correctly where the path crosses itself.
• Paths composed of more than one closed sub-path do not appear correctly when the sub-path crosses or is within the one.
• Alignment is not available for Text Areas.

See the demonstration or download a copy (includes source showing how to use the Drawfile code in your own applets).

Possible future work:

• Implement JDK 2.0 code for better path and text handling
• Rewrite implementing a set of public API's for handling the Drawfile.

Comparison of JavaDraw and MyWorld Java's Drawfile viewer (from observation)

Object	JavaDraw	MyWorld Java
Sprites	All handled	No
Gifs	No	Yes
Text	Rotated and Scaled	Yes (no rotations or scaling)
Paths	Thickness, Arrowheads, Join styles Not all fills handled correctly	No thickness, no Arrowheads, Slightly better fill handling but not perfect
JPEG	Depends on Browser
TextArea	Yes - Alignment not handled	No

Further information can be found at the DCU Computer Applications archive of 4th Year projects - Java DrawFile Renderer.

Java Sprite Viewer

This is based on the Sprite processing in the Drawfile Renederer, with the ability to read sprites defined in the following modes:

20 , 21, ????

and new type sprites defined by number of colours and dpi.

This code is written with a proper API with methods to extract information about each sprite. COMING SOON

C++ Syntax Printer

This basic program outputs colored code to screen or a color printer. Download

Java/C++ Code to HTML

This program converts Java or C++ to HTML. A template HTML file can be set up. This file must contain a '*'. The source code will be added at this point. Download
