Does EO.Pdf support canvas?
We are converting our pages that contain canvas and in the generated pdf file the canvas is empty.
We are using .RenderAsPDF();

How do we fix this?

Thanks.

Hi,

EO.Pdf does support HTML5 canvas.

We tested this feature and it works fine. It is possible that you get a blank canvas if there is a delay to trigger your canvas drawing script and the converter cut in before your drawing code is called. In that case you can increase HtmlToPdfOptions.MinLoadWaitTime and see if it helps:

If the problem continues, please try to isolate the problem into a small test page and post the test page. Once we have that we will try to run it here to see if we can reproduce the problem. Usually as soon as we can reproduce it, we can get to the bottom of it.

Thanks!
