cpdf.js: A JavaScript interface to cpdf
=======================================
// CHAPTER -1: Introduction
For development server-side with node: cpdf.js / cpdflib.js
Use
---
(Minified versions cpdf.min.js and cpdflib.min.js)
For development server-side with node: cpdf.js (minified version cpdf.min.js)
Load with "const cpdf = require('cpdf.js')" if installed in npm, or "const cpdf
= require('./cpdf.js')" to load from current directory.
@ -16,307 +16,27 @@ Load with <script src="cpdf.browser.js"></script> or similar.
Concurrency
===========
-----------
cpdf.js is synchronous and non-re-entrant.
Data types
==========
----------
Arguments are integers, floating point numbers, strings, or arrays of type
UInt8Array. Page ranges are represented by arrays of numbers.
Arguments are numbers, strings, or arrays (of type UInt8Array for data). Page
ranges are represented by arrays of numbers.
Memory Management
=================
-----------------
A PDF n must be explicitly deallocated with deletePdf(n).
A PDF p must be explicitly deallocated with deletePdf(p).
Errors
======
------
Any function may raise an exception, containing a string describing the problem.
Enumerations and data structures
================================
These are used throughout cpdf.js, but are collected here for reference.
