Given that we've not shipped, nor used, anything except binary CMaps for years let's just cache them unconditionally (since that's a tiny bit less code).
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.
This moves more functionality into the base-class, rather than having to duplicate that in the extending classes.
For consistency, also updates the `BaseStandardFontDataFactory` and introduces more `async`/`await` in various relevant code.
By using "data-l10n-attrs" it's possible to instruct Fluent to localize *custom* attributes, which means that we don't need to manually translate/update the "default-content" in FreeText editors.
This way we allow the rest of the packages to be loaded successfully, such that e.g. the Node.js unit-tests work correctly.
Note that this occurred after updating the `node-canvas` package to version `3.0.0-rc2`, however it's not immediately clear to me if it's a problem there or in the `path2d` package; see also nilzona/path2d-polyfill/issues/84.
- Change the "message" event handler function to a private method.
- Remove the "message" event listener with an `AbortSignal`.
- Extend the `LoopbackPort`-class with `AbortSignal` support.
The code parses the /RBGroups entry in the OC configuration dict and adds the property `rbGroups' to instances of the OptionalContentGroup class. rbGroups takes an array of Sets, where each Set instance represents an RB group the OptionalContentGroup instance is a member of. Such a Set instance contains all OCG ids within the corresponding RB group. RB groups an OCG is associated with are processed when its visibility is set to true, as required by the PDF spec.
Since this value is used to allocate an array, it makes sense to avoid to use too much memory.
From the specs, this value must be in the range [0; 255] (see section 8.6.6.3).
This patch removes the unused property 'highVal'.
When playing with a pen, I noticed that sometimes a free highlight has still its
gray outline when an other one is drawn: for any reason the pointerleave event isn't
triggered.
After PR 18845 we're accessing this getter more, hence it seems like a good idea to ensure that the initial `formInfo` access is covered as well.
While unlikely to be a problem in practice, at least theoretically that data may not be available and the code in `fieldObjects` could thus currently be *unintentionally* invoked more than once.
A recent change in Firefox induced too much difference between the text widths computed in using a Canvas
and the ones computed by the text layout engine when rendering the text layer. Consequently, the
text selection can be bad on Windows with some fonts like Arial or Consolas.
This patch is a workaround to try to use in first place some fonts which don't have the problem.
It fixes#18849.
When such an annotation is deleted, we make sure that there are some data
to restore.
The version of this patch was making undoing a svg deletion buggy, so it's fixed now and
an integration test has been added for this case.
Given the following excerpt from the [Wikipedia article](https://en.wikipedia.org/wiki/Gill_Sans), mapping this to Helvetica should hopefully be fine:
> It has been described as "the British Helvetica" because of its lasting popularity in British design.
Given that the `WorkerTransport`-constructor will access all possible factory-instances, let's ensure that the `transportFactory`-object always has a consistent shape regardless of other options.
Also, since `useWorkerFetch` is always true in MOZCENTRAL builds we never need to create `CMapReaderFactory`/`StandardFontDataFactory`-instances there.
This unifies the various factory-options, since it's consistent with `CMapReaderFactory`/`StandardFontDataFactory`, and ensures that any needed parameters will always be consistently provided when creating `CanvasFactory`/`FilterFactory`-instances.
As shown in the modified example this may simplify some custom implementations, since we now provide the ability to access the `CanvasFactory`-instance used with a particular `getDocument`-invocation.
