pstools_r

Rust version of pstools -- very lightweight PostScript file writing interface

The crate can be used as a callable library; it can also build a stand-alone tool that parses inputs with simple commands.

Example - Calling from Rust

let mut pst = PSTool::new();
// pst.add_box(5.0, 5.0, 20.0, 30.0);
// pst.set_color(0.3, 0.4, 0.2, 1.0);
// pst.add_text(20.0, 10.0, "Hello world".to_string());
pst.demo(); // Demonstrates the various features
pst.generate("demo.ps".to_string());

Generates something like this:

The "demo" method for the PSTool struct walks through a variety of features, and is intended to be a quick-reference for how things work.

Text File Interface

The stand-alone version parses simple text files, line by line. The following text produces a PS file as shown.

# A sample input file for the PSTool command line tool
# Blank lines and lines with # at start are ignored
