Invalid String Length When Saving PDF

Thank you for submitting an issue to jsPDF. Please read carefully.

Are you using the latest version of jsPDF? Yes (1.3.5)

Have you tried using jspdf.debug.js? Yes

Steps to reproduce

1. Add images to a jsPDF object that would generate a file string at around 384859244 characters. (~ 130 pages with full page canvas images generated via html2canvas)
2. Save File.
3. Observe Array.join error due to string being too long. (jspdf.debug.js; line 1051)

What I saw The save function silently fails, and a console log error displays with an Invalid string length error:

index.js:2177 Error in function Array.join (native): Invalid string length RangeError: Invalid string length
    at Array.join (native)
    at buildDocument (jspdf.debug.js:1051)
    at getArrayBuffer (jspdf.debug.js:1073)
    at getBlob (jspdf.debug.js:1083)
    at Object.<anonymous> (jspdf.debug.js:1112)
    at Object.__safeCallWrapper [as output] (jspdf.debug.js:621)
    at Object.API.save (jspdf.debug.js:2191)

What I expected I expected the pdf file to save.

Actually the problem is that javascript can only handle a specific length of a string. And this is the problem, because the mentioned line is content.join(‘\n’);

We can not modify the string length of the javascript engine. Probably we have to reduce the amount of memory/string length by using compression.

I had this issue as well our reports generate 3000+ pages with images attached. we were running out of memory but as it stands now. We managed to fix the issue. but we are not using html2canvas.
