Asciidia generates bitmap or vector files from simple ASCII diagrams. In that it is similar to programs like ditaa. It's build on top of a plugin architecture to make it easy to enhance it with additional diagram or drawing plugins. Currently available plugin types are:
- simple ASCII diagrams, currently not as many features as what ditaa provides, though
- directory tree diagrams
- syntax-diagrams (railroad diagrams) by specifying an EBNF
- identicon generator
Asciidia can directly generate SVG and ImageMagick MVG files, it can make use of ImageMagick "convert" utility to render to many other image formats, too.
-h show information about command-line arguments. provide a diagram type with '-t' to show help about the plugin -v show version information -t plugin type to load. available plugins are: diagram ebnf identicon test tree -i input filename or '-' for STDIN -o output filename or '-' for STDOUT -c defines the widht/height of each cell / character on the canvas in pixel. Notation is ...x... (width x height) or ... (width x width). -s scales image. notation is ...x... (width x height) whereas ... is a number to scale to. if width or height are ommited, image will be scaled by keeping aspect ratio.
It's possible to specify an output format by prefixing the output filename in the form
./asciidia.php -t ebnf -i rules.ebnf -o svg:diagram.svg
- php 5.3
- imagemagick is only required, if output format is not 'svg'
The following embedded image was created on Mac OS X using asciidia and inkscape with the command:
/Applications/Inkscape.app/Contents/Resources/bin/inkscape \ -z -e test/ebnf.png -w 500 \ <(asciidia -t ebnf -i test/ebnf.txt -o svg:-)

- The sprites were being drawn with an additional 1px per width and height and had bleeding edges in the final image.
- The rotations didn't completely match the ones in the original PHP Identicon script.
