A pure-Java implementation of Apple QuickDraw

This piece of code is mainly setup to parse the binary QuickDraw PICT format specified in "Inside Macintosh - Imaging with QuickDraw". In particular, version 1 of the PICT file format is targeted for now. The goal is to be able to convert this type of vector image file into SVG or (E)PS files.

A PICTv1 file consists of a 512-byte proprietary header (which is skipped by default for now). The size of the picture (in bytes) as well as a frame Rect are defined next. After that (until the end of the file) follows an opcode and potential parameter data. The opcodes define drawing operations available in the QuickDraw API.

The parser entry is in the Picture class.

For now, output is done using matplotlib through JyPlot.
A demo plot of the test image (for which the byte stream is given in Inside Macintosh) can be seen here:
