// CHAPTER -1: Introduction
/**
Use
---
coherentpdf.js can be used from both node and the browser.
The file `cpdflibtest.js` uses every function in coherentpdf.js. Call `./run`
to run it in node.
For development server-side with node: `coherentpdf.js` (minified version
`coherentpdf.min.js`). Load with `const coherentpdf = require('coherentpdf')`
if installed in npm, or `const coherentpdf = require('./coherentpdf.js')` to
load from current directory.
For development client-side with the browser : `coherentpdf.browser.js`
(minified version for deployment : `coherentpdf.browser.min.js`). Load with
`<script src="coherentpdf.browser.js"></script>` or similar.
Data types
----------
Arguments are numbers, strings, or arrays (of type UInt8Array for data). Page
ranges are represented by arrays of numbers.
Memory Management
-----------------
A PDF p must be explicitly deallocated with deletePdf(p).
Errors
------
Any function may raise an exception, containing a string describing the problem.
Concurrency
-----------
coherentpdf.js is synchronous and non-re-entrant. In the browser, best used in a worker.
