postscript-maker.js

A JavaScript library for generating PostScript files.

Requirements

The main postscript document generator has no strict or hard dependencies, however if you wish to make use of the FontMetric helper you will need to download the AFM file(s) for your font(s) as well as use the glyphlist.txt file found in this repo.

Specs

In addition to working normally with standard web browsers when included globally, this library also plays nicely with:

• node.js
• RequireJS
• Webpack
• Browserify

Installation

Normal

<script src="font_metric.js"></script>
<script src="postscript_document.js"></script>
<script>
  /* FontMetric and PostScriptDocument will be available globally */
  /* your code goes here */
</script>

AMD

require(['font_metric', 'postscript_document'], function(FontMetric, PostScriptDocument) {
  /* your code goes here */
});

Browserify, Webpack and node.js

var FontMetric = require('./font_metric');
var PostScriptDocument = require('./postscript_document');

/* your code goes here */

Usage

var afmData = read_file_as_string('path/to/your/font.afm');
var glyphData = read_file_as_string('glyphlist.txt');

var helvetica = new FontMetric({
  'file': afmData,
  'glyphlist': glyphData
});

var doc = new PostScriptDocument({
  'author': 'John Doe',
  'title': 'My Report'
});

var page = doc.addPage();

page.push({
  type: 'text',
  text: 'Hello World',
  x: 10,
  y: 10,
  fontSize: 27
});

page.push({
  type: 'box',
  x: 100,
  y: 200,
  w: 400,
  h: 300,
  color: '#000088'
});

var outputFile = doc.render();

/* save, write, download or echo the resulting outputFile which will be a simple string */

Options

fontSize, integer
lineWidth, integer

API
