Currently this unit-test will pass just fine if compression is disabled, e.g. by commenting out the relevant code in the `src/core/writer.js` file.
While we don't have a simple way of *directly* checking that the Annotation text-content is compressed, we can however use the resulting file-size as a fairly good proxy. (Note that if compression is disabled the file-size is more than doubled.)
Given that the `PDFDocumentLoadingTask.destroy()`-method is documented as being asynchronous, you thus need to await its completion before attempting to load a new PDF document when using the global `workerPort`.
If you don't await destruction as intended then a new `getDocument`-call can remain pending indefinitely, without any kind of indication of the problem, as shown in the issue.
In order to improve the current situation, without unnecessarily complicating the API-implementation, we'll now throw during the `getDocument`-call if the global `workerPort` is in the process of being destroyed.
This part of the code-base has apparently never been covered by any tests, hence the patch adds unit-tests for both the *correct* usage (awaiting destruction) as well as the specific case outlined in the issue.
The main stamp button will be used to just enter in a add/edit image mode:
- the user can add a new image in using the new button.
- the user can edit an image in resizing, moving it.
In image mode, when the user clicks outside on the page but not on an editor,
then all the selected editors will be unselected.
Given that the FieldObjects are parsed in parallel, in combination with the existing caching in the `getPage`-method and `annotations`-getter, adding additional caches for this fallback code-path doesn't seem entirely necessary.
When moving an element in the DOM, the focus is potentially lost, so we need to make sure
that the focused element before the translation will get back its focus after it.
But we must take care to not execute any focus/blur callbacks because the user didn't
do anything which should trigger such events: it's a detail of implementation. For example,
when several editors are selected and moved, then at the end the same must be selected, so
no element receive a focus event which will set it as selected.
There are 2 rotation we've to deal with: the viewer one and the editor one.
The previous implementation was a bit complex and having to deal with these
rotation would have potentially increase it.
So this patch aims to simplify the implementation and deal with all the possible
cases.
The main idea is to transform the mouse deltas according to the rotations and then
apply the resizing in the page coordinates system.
This method is very old, however with the exception of the auto-print hack (when scripting is disabled) in the viewer it's never actually been used.
Most likely the idea with `PDFDocumentProxy.getJavaScript` was that it'd be useful if scripting support was added, however it turned out that it was a bit too simplistic and instead a number of new methods were added for the scripting use-cases.
When searching for "endobj"-operators, make sure that we don't accidentally match a "trailer"-string in /Content-streams without /Filter-entries (i.e. streams that contain "raw" and thus human-readable data).
When an editor is selected in using the keyboard then it has the focus.
But then if the editor is unselected with Escape key then the focus must
be removed otherwise we still have a blue outline around it.
And add few missing timeout in the integration tests.
Selected editors can be moved in using the arrows:
- up/down/left/right will move the editors of 1 in page unit;
- ctrl (or meta)+up/down/left/right will move them of 10 in page unit.
The keyboard shortcuts (copy, paste, ...) didn't work correctly when the
main container was not focused.
This patch adds few waitForTimeout in the integration test for FreeText
in order to avoid possible intermittent failures.
When the flag is set, the appearance has to be generated from the value so it's
useless/meaningless to extract the content from the existing appearance.
When a pdf has /NeedAppearances set to true, the annotation appearance must be
generated from its value and we must take into account the hasOwnCanvas property.
By leveraging import maps we can get rid of *most* of the remaining `require`-calls in the `src/display/`-folder, since we should strive to use modern `import`-statements wherever possible.
The only remaining cases are Node.js-specific dependencies, since those seem very difficult to convert unless we start producing a bundle *specifically* for Node.js environments.
With the changes in the previous patch the `isNodeJS`-helper no longer needs to live in its own file, which helps get rid of a closure in the *built* files.
Currently this class contains a few "special" code-paths for the COMPONENTS build-target, which normally wouldn't be a problem. However, in this particular case that means accessing code that we don't want to include unconditionally in all builds.
This is currently implemented using build-time `require`-calls which we nowadays want to avoid, and we should strive to remove all such cases from the code-base. (Generally speaking `import` is the future, and build-tools may not always play well with a mix of both formats.)
We can easily improve things here by using sub-classing for the COMPONENTS build-target, and then use the ability to re-name when exporting (to avoid breaking existing code).
Occasionally some test-suites may fail to start on the bots, however that's not correctly reflected in the botio-output posted to GitHub which makes it easy to accidentally overlook this situation.
Looking at the raw logs when that happens they always seem to contain a line such as `Run NaN tests` which means that we should be able to easily make this situation a *failure* as intended.
- Take into account the page translation,
- Take into account the correct translation for the editor border,
- Take into account the position of the first glyph in the annotation,
- Take into account the rotation of the editor.
Close#16633.
