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.
Given that the sub-title of that document is "Public domain texts for young people." and that the images have clear sources at the end of the document, it should (hopefully) be OK to add it to the repository rather than relying on a linked test-case.
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.
This is similar to a lot of other code, where we've been replacing explicit `removeEventListener`-calls.
Given the somewhat limited availability of `AbortSignal.any()`, see [MDN](https://developer.mozilla.org/en-US/docs/Web/API/AbortSignal/any_static#browser_compatibility), this event listener will no longer be immediately removed in older browsers (however that should be fine).
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.
The default `page.type()` API from Puppeteer works for text fields that
only dispatch a sandbox event on e.g. focus loss (i.e. after all
characters have been inserted), and for those we can also use the
default typing delay from Puppeteer instead of defining our own value.
However, it doesn't work correctly for text fields where every character
insertion dispatches a sandbox event. This is because processing the
sandbox event takes some time and Puppeteer must wait for that before it
can (safely) insert the next character. This commit therefore introduces
a helper function to type a given value correctly in such text fields.
Not only does this fix intermittent failures if our delay was too low
for sandbox processing to complete, but it also speeds up the tests by
eliminating our delays in places where they were (much) higher than
necessary. In total the runtime of the scripting integration test suite
goes from 137 seconds before this patch to 100 seconds after this patch.
Note that the new version of `eslint-plugin-import` contains support
for ESLint 9.
Moreover, the new version of Babel removed the leading space for import
comments (see https://github.com/babel/babel/pull/16780), so we update
the corresponding test expectation to match this.
Fixes a part of #17928.
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.
