Generate a PDF Report from Forge Viewer

Here is a quick way to generate a PDF report of the LMV canvas through the browser.
It uses the [jsPDF](https://parall.ax/products/jspdf) library.

DEMO  https://wallabyway.github.io/forge-pdf-report/

Result:  Floor1-report.PDF

Update (2020):

If you are having problems capturing the PDF, on mobile (IOS or Android), try using the following method instead:

viewer.impl.getScreenShotProgressive(..)

How to use:

Steps:

1. Add this to your `index.html` ...

<script src="https://unpkg.com/jspdf/dist/jspdf.min.js"></script>

 
2. Take a screenshot of LMV canvas using `getScreenShotBuffer()`, like this ...

viewer.getScreenShotBuffer(
 viewer.canvas.width,
 viewer.canvas.height, 
 img => createPDF(img)); 
});

3. Then add the PNG into a new PDF using jsPDF, like this...

function createPDF(imgData) {
    var doc = new jsPDF()
    doc.setFontSize(40)
    doc.text(35, 25, 'ForgeViewer PDF report');
    doc.addImage(imgData, 'JPEG', 10, 40, 180, 80);
    doc.save('report-floor1.pdf')
}

All done !
