Obviously it doesn't make sense to call that method without providing an `AnnotationStorage`-instance, however we should ensure that doing so won't cause errors.
Hence we need to check that `annotationStorage` is actually defined, before attempting to call its `resetModified` method.
This commit makes the following improvements:
- The code is similar to the other interactive form widgets now, with a
clear note for the only difference.
- Calling `getOrCreateValue` unconditionally ensures that choice widgets
always have a value in the annotation storage. Previously we only
inserted a value in the annotation storage when an option matched or
when a selection was changed. However, this causes breakage when
saving/printing because comboboxes, which we don't fully support yet
but are rendered, might not have a value in storage at all. Their
field value might not match any option since it allows the user to
enter a custom value.
- Calling `getOrCreateValue` unconditionally ensures that forms with
choice widgets no longer always trigger a warning when the user
navigates away from the page. This fixes

Given that `renderInteractiveForms` is now enabled by default in "full" viewer, it seems reasonable to enable it by default in the viewer components as well.
Especially considering that it's simple to disable, when creating the affected components, for anyone implementing their own viewer.
The export value is used when the document is saved, so it should also
be used when the document is opened to determine which choice widget
option is selected. The display value is, as the name implies, only to
be used for viewer display purposes and not for other logic.
This makes sure that in the document from #12233 the "Favourite colour"
choice widget is correctly initialized with "Red" instead of "Black"
because the field value is equal to the export value (always the case),
but not the display value (not always the case). Moreover, saving now
also correctly uses the export value and not the display value.

This allows Firefox trigger a "save" event from ctrl/cmd+s or the "Save
Page As" context menu, which in turn lets pdf.js generate a new PDF if
there is form data to save.
I also now use `sourceEventType` on downloads so Firefox can determine if
it should launch the "open with" dialog or "save as" dialog.
This is *similar* to the existing transfer function support for SMasks, but extended to simple image data.
Please note that the extra amount of data now being sent to the worker-thread, for affected /ExtGState entries, is limited to *at most* 4 `Uint8Array`s each with a length of 256 elements.

- Initialize the `AnnotationStorage`-instance, on `PDFDocumentProxy`, lazily.
- Change the `AnnotationStorage` to use a `Map` internally, rather than a regular Object (simplifies the following points).
- Let `AnnotationStorage.getAll` return `null` when there's no data stored, to avoid unnecessary parsing on the worker-thread. This ought to "just work", since the worker-thread code *should* already handle the `!annotationStorage` case everywhere.
- Add a new `AnnotationStorage.size` getter, to be able to easily tell if there's any data stored.
While the parameter name (clearly) suggests that an `AnnotationStorage`-instance is expected, looking at the only call-sites that include the parameter (i.e. the `PDFPrintServiceFactory` instances) it actually contains just a normal Object.
Hence it seems much more reasonable to actually pass a valid `AnnotationStorage`-instance, as the name suggests, and simply have `PDFPageProxy.render` do the `annotationStorage.getAll()` call. (Since we cannot send an `AnnotationStorage`-instance as-is to the worker-thread, given the "structured clone algorithm".)
Over time we used multiple different formats for JSDoc comments. This
commit standardizes those formats to the one we used most often.
Moreover, this removes the example in the outline endpoint documentation
since it now has a proper type definition and it didn't render correctly
in JSDoc.
This commit:
- formats the documentation block according to the standards;
- replaces the callback definitions with the `function` type (we have
that for other definitions already and the callback type was not
rendered correctly by JSDoc);
- synchronizes the type documentation and the class documentation;
- fixes the documentation by making it easier to read and making sure
that all optional properties are indicated as such;
- uses the `@link` tag to indicate links to other code.
The `typestest` still passes and JSDoc now renders this class correctly.
Add a new method to the API to get the optional content configuration. Add
a new render task param that accepts the above configuration.
For now, the optional content is not controllable by the user in
the viewer, but renders with the default configuration in the PDF.
All of the test files added exhibit different uses of optional content.
Fixes#269.
Fix test to work with optional content.
- Change the stopAtErrors test to ensure the operator list has something,
instead of asserting the exact number of operators.
These errors can/will occur if data is still loading when the document is destroyed, which is the case in the API unit-tests that load the `tracemonkey.pdf` file.
While this patch prevents these kind of problems, and thus allows us to update Jasmine again, I cannot help but thinking that it's slightly "hacky". Basically, we'll simply catch and ignore (some) rejected promises once the document is destroyed and/or its data loading is aborted. However, I don't *think* that these changes should cause issues in general, since we don't really care about errors once document destruction has started (note e.g. the fair number of `catch` handlers ignoring `AbortException`s already).
*The [api-minor] label probably ought to have been added to the original PR, given the changes to the `createAnnotationLayerBuilder` signature (if nothing else).*
This patch fixes the following things:
- Let the `AnnotationLayer.render` method create an `AnnotationStorage`-instance if none was provided, thus making the parameter *properly* optional. This not only fixes the reference tests, it also prevents issues when the viewer components are used.
- Stop exporting `AnnotationStorage` in the official API, i.e. the `src/pdf.js` file, since it's no longer necessary given the change above. Generally speaking, unless absolutely necessary we probably shouldn't export unused things in the API.
- Fix a number of JSDocs `typedef`s, in `src/display/` and `web/` code, to actually account for the new `annotationStorage` parameter.
- Update `web/interfaces.js` to account for the changes in `createAnnotationLayerBuilder`.
- Initialize the storage, in `AnnotationStorage`, using `Object.create(null)` rather than `{}` (which is the PDF.js default).
This PR adds typescript definitions from the JSDoc already present.
It adds a new gulp-target 'types' that calls 'tsc', the typescript
compiler, to create the definitions.
To use the definitions, users can simply do the following:
```
import {getDocument, GlobalWorkerOptions} from "pdfjs-dist";
import pdfjsWorker from "pdfjs-dist/build/pdf.worker.entry";
GlobalWorkerOptions.workerSrc = pdfjsWorker;
const pdf = await getDocument("file:///some.pdf").promise;
```

Besides making general sense, as far as I can tell, this patch should also prevent *one* source of `Uncaught (in promise) ...` exceptions.
Unfortunately `reason instanceof AbortError` doesn't work here, since `AbortError` isn't actually defined in browsers; note how even the DOM specification contains an example using the `name` property: https://dom.spec.whatwg.org/#aborting-ongoing-activities
This patch prevents the following errors from being logged in the console, when the unit-tests are running:
- Firefox: `Uncaught (in promise) DOMException: The operation was aborted.`
- Chrome: `Uncaught (in promise) DOMException: The user aborted a request.`
There's quite frankly no particular reason to special-case Type3-fonts with image resources, which are very rare anyway, now that we have a general mechanism for sending/receiving images globally.
Originally there weren't any (generally) good ways to handle errors gracefully, on the worker-side, however that's no longer the case and we can simply fallback to the existing `ignoreErrors` functionality instead.
Also, please note that the "no `/XObject` found"-scenario should be *extremely* unlikely in practice and would only occur in corrupt/broken documents.
Note that the `PartialEvaluator.getOperatorList` case is especially bad currently, since we'll simply (attempt to) send the data as-is to the main-thread. This is quite bad, since in a corrupt/broken document the data *could* contain anything and e.g. be unclonable (which would cause breaking errors).
Also, we're (obviously) not attempting to do anything with this "raw" `OPS.paintXObject` data on the main-thread and simply ensuring that we never send it definately seems like the correct approach.
This moves, and slightly simplifies, code that's currently residing in the unit-test utils into the actual library, such that it's bundled with `GENERIC`-builds and used in e.g. the API-code.
As an added bonus, this also brings out-of-the-box support for CMaps in e.g. the Node.js examples.
