[Solved]Save As Pdf do not save links

I can confirm that with the PDF produced by the "right-click on page -> Save as pdf" feature, not all links are clickable.

I don't know if it's due to an actual bug or if the code that generates the PDF is just limited in how it detects HTML links.

On https://forums.opera.com/category/11/opera-for-windows, if you right-click on a link to a thread and inspect it, you can see that it is indeed an HTML anchor element and not some other element that's just made clickable by Javascript. Given that, I'm assuming the the "Save as PDF" code just isn't picking up those anchor elements because they're added to the page dynamically with Javascript or something in a way that causes them not to be detected.

Given that, I would assume Opera could be improved to catch more links.

It could be as simple as this:

test.html:

<script>
    window.addEventListener("DOMContentLoaded", function() {
        var a = document.createElement("a");
        a.href = "https://example.com/";
        a.textContent = "Am I clickable in a PDF?";
        document.body.appendChild(a);
    });
</script>

Load test.html in Opera, right-click the page and choose "save as pdf". Then, open the PDF and see if it's clickable. If it's not, it means Opera doesn't detect dynamically-added links. If so, it's something Opera should fix if possible.

You are right.
Opera do not find dynamic links in save as pdf (but do it in print to pdf).
Probably opera take semantic information from initialization page step for save as pdf. However opera take actual view of page for save as pdf (for example you can open some sub item on the page which do not showing on the page by default, and opera do save page in actual state).

It is a pity that we have such asymmetry. I think it is not a true bug. Just developers have had some trouble with it. And they implemented this asymmetric approach.

Do you know where do i can see programme code of this functional or it is not a public code?

Opera's source code is not public. But, Since it uses Chromium, you can look at Chromium source code.

I think Chromium and Opera's PDF functions are done with https://opensource.google/projects/pdfium. Also, see https://cs.chromium.org/chromium/src/pdf/pdfium/pdfium_print.cc?g=0. I'm assuming Opera wrote some custom code for the "Save as PDF" function that makes use of PDFium. But, theat custom code probably isn't available to the public. But, don't really know for sure.

On a side, there might be a "Save as PDF" extension that does things better than Opera's feature. You can look at https://chrome.google.com/webstore/search/save as pdf?_category=extensions and https://addons.opera.com/en/search/?query=pdf.

PDFs created via Page > Save as PDF do not seem to save any URLs anymore since version 65.0.3467.38

Opera 65.0.3467.42 Stable x64, Win10 Prof.

A Former User

Addendum: The same goes for Opera Developer 66.0.3502.0 x64.

Didn't test Opera beta.

I tested this example. test.html
If a PDF file is created in Opera 63 and later, in the created PDF, the link is not clickable.
If a PDF file is created in Opera 62 and below, the link is clickable.

In the PDF file created in Opera 65 and 66, it seems that any links are not clickable.

@johnd78 Thanks. If you get a chance, and can narrow it down to the first build with the problem, that'd help.

In the 63 changelog, the only PDF change I see is "DNA-78740 Save as pdf does not work on sidebar’s pane". The change is listed for 2 different builds.

The first build in which all links are not clickable when saved to PDF - Opera Developer 65.0.3454.0

@johnd78 Thanks.

I don't see much in the changelog that would cause it beside a Chromium update. The Chromium update has quite a few PDF changes though.

Filed bug DNA-82503.

A Former User @burnout426

@burnout426 Fixed in Opera 69.0.3623.0 developer.

@johnd78 Confirmed fix in that build with this test at least.

The bug was more to do with links that didn't have class attributes or something than just dynamic links. Anyway, all seems to be good now in Opera Developer.

A Former User

I now have Opera 67.0.3575.79. And “Save As PDF” doesn't even save simple links from wikipedia.

@operfree The fix isn't included in Opera 67. It's in Opera 68 (Opera Beta) and Opera 69 (Opera Developer). However, it looks like there's more work to do as the table of contents links on https://en.wikipedia.org/wiki/Opera_(web_browser) don't get saved as links.

I guess those never worked, so never mind on that part.

When using this option, original url is not stored within the generated PDF. Is that also a bug or something that never worked?

It would be great if the url is stored in the Title or Subject field of PDF's metadata.

@milolav I guess it simply was never implemented.
