An SVG renderer for Atari 8-bit computers, written in Turbo-BASIC XL

Renderific 1.0 - Readme

Renderific is an SVG renderer for Atari 8-bit computers, written in Turbo-BASIC XL. It tries to parse SVG Tiny files and draw them on screen and/or on an Atari 1020 plotter.

Sample output:

Sample Image 1 - flower Sample Image 2 - curve Sample Image 3 - triangle maze Sample Image 4 - Atari 800 logo Sample Image 5 - woodsy scene from Transylvania game Sample Image 6 - ANTIC podcast logo Sample Image 7 - circuit diagram Sample Image 8 - twisted polygon

Thanks to @PneumaticDeath for help on the Bézier math, and @BillLange1968 for plotter testing.

Bugs and things

I've found some SVGs that seem to intentionally draw in negative regions. I'm not sure what their intention is - is the viewport moved to include part of the negative quadrants? Anyway, Renderific doesn't support that. Many of the SVG flags at do this. (I'm looking at you, Djibouti and Bouvet Island.)

I kind of wanted to add the "a"rc path command, although it is not in SVG Tiny. It looks complicated.

It doesn't handle FILLs.

I did not support the SVG TEXT command while rendering to the plotter. It's probably easy to add but given the other plotter issues I thought it best to wait.

The program really wants the file to end with </svg>, otherwise you'll get an EOF error.

If any single command in the SVG file (e.g. very long PATH commands) exceeds the DIMensioned length of A$ (10000 characters) the program will crash.

However, the program should nicely handle SVG files with any type of line ending, e.g. Atari, Mac, Windows, whatever.
