and tweak a bit the highlight one (e.g. it's useless to have 64 bits floating point numbers
when 32 bits ones are enough).
It's a required step for the refactoring of the ink tool (in order to use the draw layer).
It avoids to call several functions acting on the same SVG element.
We can remove most feature testing from this helper function, with the exception of `randomUUID` since that's only available in "secure contexts", and also remove the fallback code-path.
Note that this code was only added for Node.js compatibility, and it's no longer necessary now that the minimum support version is `20`; see also https://developer.mozilla.org/en-US/docs/Web/API/Crypto#browser_compatibility
Finally, this patch also adds a basic unit-test for the helper function.
This integration test fails intermittently, locally at least in Chrome
with Puppeteer 23.4.0+, with the following errors:
```
In chrome: Expected '123Hello' to equal 'Hello123'.
In chrome: Expected '123Hello' to equal '123'.
```
This happens because the test before it left queued sandbox events
behind. We don't close the document between tests, so those get run
when we click the textbox in this test and that interferes with our
selection/typing actions. This commit fixes the issue by flushing the
queued sandbox events in the first test, which makes sure that state
no longer leaks through to the next test and thus improves isolation.
Morever, similar to commit 3adf8b6 we use safer assertions to avoid
further intermittent failures, and we replace the `page.$eval` call
with a simpler Home button push like we already do in e.g. the test
helpers. This combined makes the code shorter and simpler.
The purpose of these changes is to make it more difficult to accidentally include logging statements, used during development and debugging, when submitting patches for review.
For (almost) all code residing in the `src/` folder we should use our existing helper functions to ensure that all logging can be controlled via the `verbosity` API-option.
For the `test/unit/` respectively `test/integration/` folders we shouldn't need any "normal" logging, but it should be OK to print the *occasional* warning/error message.

Python 3.13 is the current version and was released over a month ago
(see https://devguide.python.org/versions). The dependencies we use now
support Python 3.13, most importantly `fonttools` which uses OS-specific
builds and for which compatibility got introduced in
https://github.com/fonttools/fonttools/pull/3656 and the corresponding
`cp313` wheels for all distributions are published on
https://pypi.org/project/fonttools/#files.
Moreover, we fix forgotten `npx` usage in the font tests README which
was encountered while testing this patch.
Flat config is the new config system used by ESLint 9.
To make the migration easier, they also added
flat config support to ESLint 8.
This commit migrates the various ESLint configs in the repository to use
the new system, **without** upgrading to ESLint 9 yet.
The problem with the referenced PDF document has nothing to do with invalid dates, as the issue seems to suggest, but rather with the fact that it has neither an XRef table nor a trailer dictionary.
Given that crucial parts of the internal document structure is missing, you might argue that it's not really a PDF document.
In an attempt to support this kind of corruption, we'll simply iterate through all (previously found) XRef entries and pick one that *might* be a valid /Root dictionary.
There's obviously no guarantee that this works, and it might not be fast in larger PDF documents, but at least it cannot be any worse than *immediately* throwing `InvalidPDFException` as we previously did here.
*Please note:* I'm totally fine with this patch being rejected, since it's somewhat questionable if we should actually attempt to support "PDF documents" with this level of corruption.
This integration test fails intermittently because we're not
(correctly) awaiting the sandbox actions. The `27R` field in
`issue14862.pdf` triggers sandbox events for every typing action, but
for the backspace and "a" character typing actions we weren't awaiting
the sandbox trip at all, and for other places we weren't awaiting it
fully (causing some characters to be missed in the assertion).
This commit fixes the issues by using the appropriate helper functions,
similar to what we did in PR #18399. Not only is this shorter in terms
of code, but it also fixed the near-permafail for this test with newer
versions of Puppeteer.
- Over time the number and size of these factories have increased, especially the `DOMFilterFactory` class, and this split should thus aid readability/maintainability of the code.
- By introducing a couple of new import maps we can avoid bundling the `DOMCMapReaderFactory`/`DOMStandardFontDataFactory` classes in the Firefox PDF Viewer, since they are dead code there given that worker-thread fetching is always being used.
- This patch has been successfully tested, by running `$ ./mach test toolkit/components/pdfjs/`, in a local Firefox artifact-build.
*Note:* This patch reduces the size of the `gulp mozcentral` output by `1.3` kilo-bytes, which isn't a lot but still cannot hurt.
One goal is to make the code for drawing with the Ink tool similar to the one to free highlighting:
it doesn't really make sense to have so different ways to do almost the same thing.
When the zoom level is high, it'll avoid to create a too big canvas covering all the page which consume
more memory, makes the drawing very slow and the overall user xp pretty bad.
A second goal is to be able to easily implement more drawing tools where we would just have to implement
how to draw from the pointer coordinates.
This extends PR 13796 to also handle the case where sub-streams contain invalid data, i.e. anything that isn't a Stream, however please note that in these cases there's no guarantee that we'll render the page "correctly".
Note that Adobe Reader, i.e. the PDF reference implementation, cannot render the last page of the referenced PDF document.
Currently we manually localize and update the DOM-elements of the AltText-button, and it seems nicer to utilize Fluent "properly" for that task.
This can be achieved by introducing an explicit `span`-element on the AltText-button (similar to e.g. the regular toolbar-buttons), and adding a few more l10n-strings, since that allows just setting the `data-l10n-id`-attribute on all the relevant DOM-elements.
Finally, note how we no longer need to localize any strings eagerly when initializing the various editors.
It fixes#18956.
In the patch #18029, for performance reasons and because I thought it was useless, I deliberately chose to not fill the mask
with the backdrop color when it's full black: it was a bad idea.
So in this patch we always add the backdrop color to the mask.
After the binary CMap format had been added there were also some ideas about *maybe* providing other formats, see [here](https://github.com/mozilla/pdf.js/pull/8064#issuecomment-279730182), however that was over seven years ago and we still only use binary CMaps.
Hence it now seems reasonable to simplify the relevant code by removing `CMapCompressionType` and instead just use a boolean to indicate the type of the built-in CMaps.
The PDF document is clearly corrupt, since it has /FontFile2 entries that are Dictionaries which obviously isn't correct.
While there's obviously no guarantee that things will look perfect this way, actually rendering the text at all should be an improvement in general.
The `getSpanRectFromText` helper function returns the location as float
values. This could be desirable in cases where the exact values matter
(for example during comparisons), but in the text layer tests we don't
need this precision. Moreover, the Puppeteer `page.mouse.move` API
apparently doesn't work correctly if float values are given as input.
Note that this test only failed because it couldn't move to the initial
selection position; any subsequent moves actually worked because the
`moveInSteps` helper function already rounded all values correctly.
This commit fixes the issue by consistently rounding all values that we
pass to Puppeteer's `page.mouse.move` API.
