Note how the `PDFAttachmentViewer` handles PDF file attachments specially, by opening them in a new window/tab, rather than forcing them to be downloaded. This is done to improve the overall UX, since browsers in general are able to handle PDF files internally.
However, for file *annotations* we're currently not attempting to do the same thing and are instead just downloading them directly. In order to unify the behaviour, without having to duplicate a lot of code, the opening of PDF file attachments is thus moved into a new `DownloadManager.openOrDownloadData` method.
- strokeColor corresponds to borderColor;
- support fillColor and textColor;
- support colors on the different annotations;
- fix typo in aforms (+test).
I happened to look at this code, and I can't for the life of me figure out why I didn't just implement it like this patch in the first place (since the current format feels overly verbose).
* don't set a value in annotationStorage by default:
- having an undefined when the annotation is rendered for saving/printing means nothing has changed so use normal appearance
- aims to fix https://bugzilla.mozilla.org/show_bug.cgi?id=1681687
* change the way to compute font size when this one is null in DA:
- make fontSize proportional to line height
- in multiline case, take into account the number of lines for text entered to adapt the font size
For DOM events all event names are lower-case, and the newly added PDF.js scripting-events thus "stick out" quite a bit. Even more so, considering that our internal `eventBus`-events follow the same naming convention.
Hence this patch, which changes the "updateFromSandbox"/"dispatchEventInSandbox" events to be lower-case instead.
Furthermore, using DOM events for communication *within* the PDF.js code itself (i.e. between code in `web/app.js` and `src/display/annotation_layer.js/`) feels *really* out of place.
That's exactly the reason that we have the `EventBus` abstraction, since it allowed us to remove prior use of DOM events, and this patch thus re-factors the code to make use of the `EventBus` instead for scripting-related events.
Obviously for events targeting a *specific element* using DOM events is still fine, but the "updatefromsandbox"/"dispatcheventinsandbox" ones should be using the `EventBus` internally.
*Drive-by change:* Use the `BaseViewer.currentScaleValue` setter unconditionally in `PDFViewerApplication._initializeJavaScript`, since it accepts either a string or a number.
- Update the `LinkAnnotationElement._bindJSAction` call-site to actually agree with the JSDocs, by passing in the `data`.
- Prevent the links created by `LinkAnnotationElement._bindJSAction` from being displayed with empty hashes; compare with e.g. `LinkAnnotationElement. _bindNamedAction`.
- The overall indentation-level in `WidgetAnnotationElement._setEventListener` can be reduced slightly by using early returns, which improves the overall readability of this method a bit. (We're also able to avoid unnecessary `in` usage here.)
- The code can also be made *slightly* more efficient overall, by moving the `this.data.actions` check into `WidgetAnnotationElement._setEventListeners` instead. This way we can avoid useless `this._setEventListener`-calls when there are no actions present.
- Actually remove the `isDown` property when destroying the scripting-instance.
- Mark all `mouseState` usage as "private" in the various classes.
- Ensure that the `AnnotationLayer` actually treats the parameter as properly *optional*, the same way that the viewer components do.
- For now remove the `mouseState` parameter from the `PDFPageView` class, and keep it only on the `BaseViewer`, since it's questionable if all of the scripting-functionality will work all that well without e.g. a full `BaseViewer`.
- Append the `mouseState` to the JSDoc for the `AnnotationElement` class, and just move its definition into the base-`AnnotationElement` class.
Each quadrilateral needs to have its own link element, so the first
quadrilateral can use the already created element, but the next
quadrilaterals need to clone that element.
Not only does this reduce boilerplate since the documentation is the
same for all annotation classes, it also wasn't correct for the
annotation types that support quadpoints since they return an array of
section elements instead of a single one.
*This is a recent regression, which I stumbled upon while working on cleaning-up the gulpfile related to `pdf.sandbox.js` building.*
By placing the `ColorConverters` functionality in the `src/display/display_utils.js` file, you end up including a *significant* chunk of the `pdf.js` file in the built `pdf.scripting.js`/`pdf.sandbox.js` files.
Given that I cannot imagine that this was actually intended, since it inflates the built files with unnecessary/unused code, this moves `ColorConverters` to a new file instead (thus breaking the dependencies).
To hopefully reduce the risk future bugs, along these lines, a big comment is also placed at the top of the new file.
Finally, the `ColorConverters` is converted to a class with static methods, since this felt slightly cleaner overall.
* remove 1st param of _createPopup (almost useless for a method)
* prepend popup div to avoid to have them on top of some highlights (and so "disable" partially mouse events)
* add a ref test for issue #12504
* in some pdf, there are actions with "event.source.hidden = ..."
* in order to handle visibility when printing, annotationStorage is extended to store multiple properties (value, hidden, editable, ...)
* When no actions then set it to null instead of empty object
* Even if a field has no actions, it needs to listen to events from the sandbox in order to be updated if an action changes something in it.
* it's faster to generate the color code in using a table for components
* it's very likely a way faster to parse (when setting the color in the canvas)
Ensure that these tooltip-only Annotations are handled as "internalLink"s, to ensure that they behave as expected in PresentationMode (e.g. they should still use a `pointer`-cursor).
Ensure that `PDFLinkService.getDestinationHash` won't create links with empty hashes, since those don't really make a lot of sense in general (this improves things for tooltip-only Annotations).
This PDF file can be used for testing: http://mirrors.ctan.org/macros/latex/contrib/pdfcomment/doc/pdfcomment.pdf#page=14
This modernizes and improves the code, by using `async`/`await` and by extracting the helper function to its own method.
To hopefully avoid confusion, given the next patch, the method is also re-named to `goToDestination` to make is slightly clearer what it actually does.
Previously this rule has been enabled in the `web/` folder, and in select files in the `src/` sub-folders.
Note that a number of the files in the `src/display/` folder were already enforcing the `no-var` rule, and thanks to Prettier the necessary re-writing will be (mostly) handled automatically.
Please find additional details about the ESLint rule at https://eslint.org/docs/rules/no-var
This changes the `transformOrigin` calculations in `AnnotationElement._createContainer` and `PopupAnnotationElement.render`, to ensure that e.g. the clickable area of annotations and/or popups are both positioned correctly.
The problem occurs for *negative* values, since they're not negated correctly because of how the `transformOrigin` strings were build; see issue 12406 for a more in-depth explanation. Previously, for negative values, the `transformOrigin` strings would thus be ignored since they're not valid.
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.
