Clipping Lines to Inside a Rectangle?

[patrick-roberts]

I'd like to call pdf.rect() then have lines drawn with pdf.lines() clipped to stay inside that rectangle. Anyone now how to add that to jsPDF?

Here's my solution:

(function(jsPDFAPI) {
    // see http://wwwimages.adobe.com/www.adobe.com/content/dam/Adobe/en/devnet/pdf/pdfs/PDF32000_2008.pdf Annex A for list of PDF stream operators
    jsPDFAPI.clip = function() {
        this.internal.write('W') // clip
        this.internal.write('S') // stroke path; necessary for clip to work
    };
})(jsPDF.API);

Call pdf.clip() after calling pdf.rect with a style argument of null

Thanks Patrick! Feel free to create a PR, but seeing the code size that could be implemented directly on jspdf.js rather than as a plugin.

how can i use it ? can you provide some example?
for example;
I tried to clip some rects inside another one like

doc.rect(10,10,10,10)
doc.rect(10,10,20,20)
doc.rect(100,100,0,0)
doc.clip()

but it didn't work.
