After the clean-up in PR 15616, the `PdfManager.onLoadedStream` method now only has a single call-site.
Hence why this patch suggests that we remove this method and replace it with an *optional* parameter in `PdfManager.requestLoadedStream` instead. By making the new behaviour opt-in, we'll thus not change any existing call-site.
- Some events, which require a user interaction, will allow those functions to be called.
But after few seconds, if there are no more user interaction, it won't be possible
anymore.
The idea is to give an opportunity to the user to leave the pdf.
- Disable print function when we're printing, the same with saving and disallow to save
on open events.
When a form isn't changed, we used the appearances we had in the file, but when
/NeedAppearances is true, all the appearances have to be regenerated whatever they're.
- In #15373, we implemented copy/paste actions in using the system
clipboard.
For any reasons, on Windows, the clipboard doesn't contain the expected
data when the tests are ran in parallel, hence the tests which are
using the clipboard need to be ran sequentially.
- Make sure that we can paste after having copied.
*This is very old code, and it could thus do with some simplification.*
Note how in the `src/core/worker.js` file we're combining both the `PdfManager.requestLoadedStream` and `PdfManager.onLoadedStream` methods in order to access the stream-data. This seems unnecessary, and it's simple enough to always let the `PdfManager.requestLoadedStream` method return the stream-data as well.
PR 13725 was only intended as a temporary work-around, and it seems that we can now revert that.
- Firefox 102 is the currently maintained ESR-branch, and the PDF.js project only supports the active one.
- Node.js now works, thanks to the `node-canvas` package, and I've confirmed locally that following the STR in issue 13724 generates a correct image.
In the referenced PDF document there are "numbers" which consist only of `-.`, and while that's obviously not valid Adobe Reader seems to handle it just fine.
Letting this method ignore more invalid "numbers" was suggested during the review of PR 14543, so let's simply relax our the validation here.
It appears that PR 15593 broke `issue12402`, and we thus need to partially restore the /Count check.
I completely missed this when looking at the test-results for PR 15593, both locally and on the bots, since the `Driver._getLastPageNumber` method would "swallow" an unavailable page number.
- When we're editing some annotations, keeping the role="text-box" make them visible
as editable and VoiceOver (Mac) is able to read the contents when they're focused;
- Add an attribute "aria-activedescendant" in order to make the content discoverable
by NVDA on Windows.
After PR 14311, and follow-up patches, we no longer require that the /Count entry (in the /Pages dictionary) is either present or even valid in order to parse/render a PDF document.
Hence it seems strange to keep this requirement for *corrupt* PDF documents, when trying to find a usable `trailer` in the `XRef.indexObjects` method.
