Create custom size PDF

[jguix]

I suggest the following patch to enable custom PDF size.

The idea is that the format parameter can take an object with width and height properties.

Example:

            var pdf = new jsPDF({
                orientation: widthMm > heightMm ? "L" : "P",
                unit: "mm",
                format: {
                    width: widthMm,
                    height: heightMm
                }
            });

In that example, the format would be widthMm x heightMm. The units of the format are the PDF units. Then, my patch creates a new pageFormat with key "custom" and size translated to standard pt units.

Please find the patch below, it only affects a few lines of the original code:

>           case 'in':  k = 72;         break;
>           case 'px':  k = 96 / 72;    break;
>           case 'pc':  k = 12;         break;
>           case 'em':  k = 12;         break;
>           case 'ex':  k = 6;          break;

>           pageFormats['custom'] = [format.width * k, format.height * k];
>           format = 'custom';
>       }

Try this:

var pdf = new jsPDF('p', 'in', [5,2]);

This will create a 5in x 2in PDF.

@Flamenco Thank you much! Couldn't find that in docs.

You can even set different sizes for every page you add:

var doc = new jsPDF('p', 'mm', [68,20]);
doc.addPage(100, 200);

Thank you guys!

That would be so nice... Any update, when the next version will be available?

EDIT: Nevermind, it works! Thanks for the great work!

var doc = new jsPDF({
orientation: 'landscape',
unit: 'mm',
format: [100, 50]
})
