1345588 - Image not visible when printing from iframe with srcdoc

Status: RESOLVED FIXED

(Core :: Printing: Output, defect)

Description

[Alex Guerra]

Attachment: An example html file that recreates the issue. I tried to condense it down as much as I could. You need to provide the image and may need to adjust the src urls.

User Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:53.0) Gecko/20100101 Firefox/53.0
Build ID: 20170306004003

Steps to reproduce:

I create an iframe with a srcdoc set as single image element. The img element's src is set to a path that doesn't have the domain name. So something like `<iframe srcdoc="<img src=&quot;/image.png&quot;>">`. I then get a reference to the iframe and try to print its contents with `myiframe.contentWindow.print()`.


Actual results:

In the browser, the image is visible within the iframe. The print process completes successfully. However, the result (using "Microsoft Print to PDF") appears to be missing the image. The print artifacts I'd expect in the margin are there (like it says about:srcdoc in the top right corner, page 1/1, etc), but the document itself appears to be completely empty.

If the path *isn't* relative (eg `src=&quot;/http://127.0.0.1/image.png&quot;`) the iframe looks identical in the browser but the image actually shows up in the result. Also, if the body of the srcdoc has some text in addition to the image with the relative path, the text shows up but the image does not.




Expected results:

The image should be visible in the resulting pdf.
