Has there been any progress on the issue?

We really need this to work with awesomeCloud!

We also really need a fix for this. Specifically, we are using D3.js, the most popular javascript charting library, and text is not being shown. You can generate a PDF from this sample page to reproduce the issue: http://bl.ocks.org/mbostock/3886208. Is it possible the issue is around your treatment of transforms (3d/2d)?

We bought EO.pdf (2013) at Aug 2014, we have the same issue mentioned by other user in this topic that the fillText in canvas cannot be rendered in the pdf. Even I used the latest EO.pdf (2014), the result is the same.

My testing code is this

<script type="text/javascript">
var ctx = document.getElementById("mycanvas").getContext("2d");

ctx.beginPath();
ctx.moveTo(0, 0);
ctx.lineTo(300, 150);
ctx.stroke();

ctx.font = "10px sans-serif";
ctx.fillText("Hello World!", 10, 50);
</script>

The pdf rendered only as a line, but the "Hello World" is disappeared.

I noticed that many users come across this, and hope that this will be fixed soon. Thanks for your attention.

Has there been any development to this issue? Canvas Text is not being rendered in PDF for me, and I'd like to understand whether it has to do with my library version.

Please fix!

Hi,

The canvas should work fine in the latest version of EO.Pdf. You can verify the test code posted by Paul with our online demo page:

https://www.essentialobjects.com/Products/EOPdf/HtmlToPdf.aspx

And you should see it works fine.

If you still run into problem, please post your test HTML (please start a separate thread) and we will look into it.

Thanks!
