Saving PDF with image fails

[rogerfar]

Create a ticket with an image, it will fail on the following line:

var datauri = ('' + type).substr(0, 6) === 'dataur'
                    ? 'data:application/pdf;base64,' + btoa(buildDocument()) : 0;

With the error:

Error: Error in function Error (native): Failed to execute 'btoa' on 'Window': The string to be encoded contains characters outside of the Latin1 range.
    at Console.$window.console.error (http://localhost:3333/App/Business/AngularErrorHandler.js:43:23)

[MrRio]

Can you try get an example running – http://jsbin.com/rilace/edit?html,js,output

[rogerfar]

Yes, here it is:

[MrRio]

Strangely, that works for me on mobile Chrome on iOS, but not on desktop

[rogerfar]

Odd thing is that .save() works, but .output() doesn't

[MrRio]

Thanks for that. Yeah that is odd. git-bisect time!

I'm seeing the same thing on Windows with latest Chrome and Firefox. Any word on a fix?

As an example, here's the image data I'm trying to add:

And here's the code:
thePDF.addImage(imageData, "PNG", 0, 0, imageWidth, imageHeight);

[mvanroon]

Same problem here. Only fails on png's for me.

[agcyphers]

I've reverted to 1.0.272 until this is addressed.

[nadous]

Same problem too. Fail with canvas having a drawn image then masked by a rounded rectangle. The Firefox error is more verbose:

Error in function n/At: String contains an invalid character DOMException [InvalidCharacterError: "String contains an invalid character"
code: 5
nsresult: 0x80530005
location: ***/jspdf.min.js:279]

See also: WindowBase64.btoa().

[Alorse]

Some progress with this issue?
If you replaced in the jspdf.min.js file:
btoa(vt())
to:
btoa(unescape(encodeURIComponent(vt())))

The file is generated correctly, but the images are not seen.

trying to render charts and pies here, same problem.
I could've live with save() if only png was better than jpeg, in the rendered pdf document

[Mario-Eis]

Same issue here. JPG works fine, PNG fails.
