- each annotation has its coordinates/dimensions expressed in percentage,
hence it's correctly positioned whatever the scale factor is;
- the font sizes are expressed in percentage too and the main font size
is scaled thanks a css var (--scale-factor);
- the rotation is now applied on the div annotationLayer;
- this patch improve the rendering of some strings where the glyph spacing
was not correct (it's a Firefox bug);
- it helps to simplify the code and it should slightly improve the update of
page (on zoom or rotation).
We want to avoid adding regular `id`s to Annotation-elements, since that means that they become "linkable" through the URL hash in a way that's not supported/intended. This could end up clashing with "named destinations", and that could easily lead to bugs; see issue 11499 and PR 11503 for some context.
Rather than using `id`s, we'll instead use a *custom* `data-element-id` attribute such that it's still possible to access the Annotation-elements directly.
Unfortunately these changes required updating most of the integration-tests, and to reduce the amount of repeated code a couple of helper functions were added.
- Since the border belongs to the section containing the HTML
counterpart of an annotation, this section must be hidden when
a JS action requires it;
- it wasn't possible to hide a button in using JS.
- Right now, we must select the tool, then click to select a page and
click to start drawing and it's a bit painful;
- so just create a new ink editor when we're hovering a page without one.
This appears to be a Microsoft-specific version of the regular Arial font, hence we simply map this to Helvetica in the same way that we treat many other Arial-named fonts.
Apparently the ESLint rule added in PR 15031 wasn't able to catch all cases that can be converted, which is probably not all that surprising given how some of these call-sites look.
- Use `Element.prepend()` to insert nodes before all other ones in the element, rather than using `firstChild` with `insertBefore`-calls; see https://developer.mozilla.org/en-US/docs/Web/API/Element/prepend
- Fix one *incorrect* `insertBefore` call, in the AnnotationLayer-code.
Initially the patch simply changed that to an `Element.before()`-call, however that broke one of the integration-tests. It turns out that the `index` may try to access a non-existent select-child, which triggers undefined behaviour; note the warning in https://developer.mozilla.org/en-US/docs/Web/API/Node/insertBefore#parameters
This only adds the minimum entries required in order to render the referenced document correctly, rather than trying to support "all" Hebrew glyphs, to ensure that all lines in `getGlyphMapForStandardFonts` are covered by tests.
*Please note:* The dates below are still a little ways off, however that obviously won't affect the existing PDF.js releases. Hence I think that we can make these changes now, since by the time of the *next* official PDF.js release they'll likely match up pretty well.[1]
While we "support" some (by now) fairly old browsers, that essentially means that the library (and viewer) will load and that the basic functionality will work as intended.[2]
However, in older browsers, some functionality may not be available and generally we'll ask users to update to a modern browser when bugs (specific to old browsers) are reported.[3]
Since we've previously settled on only supporting browsers/environments that are approximately *three years old*, this patch updates the minimum supported browsers/environments as follows:
- Chrome 76, which was released on 2019-07-30; see https://en.wikipedia.org/wiki/Google_Chrome_version_history
- Firefox ESR (as before); see https://wiki.mozilla.org/Release_Management/Calendar
- Safari 13, which was released on 2019-09-19; see https://en.wikipedia.org/wiki/Safari_version_history#Safari_13
- Node.js 14, which was release on 2020-04-21 (all older versions have reached EOL); see https://en.wikipedia.org/wiki/Node.js#Releases

[1] Given that the releases usually happen every two to three months.
[2] Assuming that a `legacy/`-build is being used, of course.
[3] In general it's never a good idea to use old/outdated browsers, since those may contain *known* security vulnerabilities.
Fixes two recent "Code scanning alerts" on GitHub, which likely happened because these calls originally used `parseInt` instead (during initial development).
After the changes in PR 14998, these operators are now no-ops in the `src/display/canvas.js` code and should no longer be necessary.
Given that `beginAnnotations`/`endAnnotations` are not in the PDF specification, but are rather *custom* PDF.js operators, it seems reasonable to stop using them now that they've become no-ops.
While `TextLayerRenderTask` apparently makes sense in TypeScript environments, given that it's being returned by the `renderTextLayer`-function in the API, we really don't want to extend the *public* API by simply exporting the class directly in `src/pdf.js` since it should never be called/initialized manually.
Hence we follow the same pattern as in PR 14013, and add some very basic unit-tests to ensure that `renderTextLayer` always returns a `TextLayerRenderTask`-instance as expected.
In PR #14717, the type was changed from a HTMLElement to a DocumentFragment.
This broke TypeScript projects that use a HTMLElement container.
To remedy this, we extend the type of container to also include HTMLElement.

The code has been slightly modified in order to make the linter
happy.
This only applies to *corrupt* PDF documents, where Annotations are missing the required /Rect-entry. Rendering PopupAnnotations unconditionally shouldn't be a problem, since we're not using a `BaseSVGFactory`-instance in that case.
In the "no fontSize available" code-path, in the `ChoiceWidgetAnnotation._getAppearance` method, we don't provide the necessary second argument when calling the `_getTextWidth`-method which will cause errors to be thrown.
- each annotation must be rendered independently of the others. So
after having rendered each annotation, the canvas states are reset
in order to have something clean to render the next one.
This method/function was added only for the `gulp image_decoders`-builds, and is completely unused elsewhere (e.g. in the Firefox PDF Viewer).
While this only reduces the size of the *built* `pdf.worker.js` file by a little over 1 kB, it can't hurt to remove completely unused code from the "normal" builds.
While calling `JSON.stringify(...)` on a class-instance obviously "works" (as in it doesn't throw), since it's really just an Object, it doesn't really make much sense in the context of the `AnnotationStorage.hash`-getter.
Also, access the *inverse* Viewport-transform correctly in `FreeTextEditor.serialize` to prevent errors being thrown when that method is invoked.
Finally, slightly updates the `AnnotationStorage.serializable`-getter to improve consistency within the class.
*This fixes a regression from PR 14754.*
We didn't lookup the image-data correctly, with the result that we tried to render some ImageMasks using a string rather than the intended TypedArray. To make matters worse, this code-path was apparently not *properly* covered by existing test-cases.
- Ensure that the modified-warning won't be displayed, when navigating away from the viewer, if the user has added custom Annotations and then *removed all* of them.
- Ensure that the *initial* editor-buttons state, i.e. the `toggled`-class, is correctly displayed in the toolbar when then viewer loads.
- Tweak the CSS-classes for the editor-buttons, such that they use the correct focus/hover-rules (similar to the sidebar-buttons).
- Remove a no longer accurate comment from the `BaseViewer.annotationEditorMode`-setter.
- Address a couple of *smaller* outstanding review comments, including some re-formatting changes, from PR 14976.
This patch contains a small optimization specifically for the case when `getDocument` is called with TypedArray-data. In that case we'll still hold onto that data, which could obviously be large, even after the "GetDocRequest"-message has been sent to the worker-thread.
In practice this will most likely not affect memory usage in any noticeable way, since the application calling `getDocument` will probably also be keeping a reference to the TypedArray-data. However, it seems like a good idea to ensure that the PDF.js API *itself* won't unnecessarily keep this data alive.
- it's a regression from PR #14247:
- before the PR, the button was rendered on the canvas whatever its status was;
- after the PR, the button image has been moved in an other canvas so when the button is not renderable
(because it has no actions) then the image is not added the HTML element.
- the buttons in the pdf in bug 1737260 or in the pdf in #14308 were not visible
- make the button always renderable but don't add the link element if it's useless.
- right now we're using the font size from the pdf itself but we use an other font
in the annotation layer. So this size doesn't really make sense and leads to bad
rendering (see pdf in #14928);
- use a sans-serif font for the fields containing text (fix issue #14736);
- remove useless padding in text-based fields (fix issue #14301);
- text fields allow/disallow scrolling bars (see bit 24 in Ff entry), so use this
value to hide/show scrollbars in annotation layer.
In the `src/display/canvas.js` code the `d1` operator will be used to set the clipping region, and it obviously cannot be empty since that prevents the Type3-glyph from rendering.
Also, the patch removes an outdated comment; refer to PR 12718.
This limits the heuristics for handling of incomplete path operators, see PR 9838, to only apply to *sequences* of such operators. In practice a couple of invalid path operators are (hopefully) unlikely to completely break rendering, whereas a sequence of them will easily lead to fairly chaotic rendering artifacts.
