- After undoing a deletion of several editors, they appeared to be selected (they had a red border)
when in fact they were not, consequently, this patch aims to remove the selectedEditor class when
an editor is removed;
- Add a test with some ink editors.
The previous version was maybe functional but definitely painful to maintain
(maybe more efficient... I don't know) so this patch aims to simplify it and
it adds some basic unit tests.
The elements in the annotationEditor layer are rearranged to make them
more accessible, but we must draw them in the order they have been created,
hence this patch adds a z-index to the editors.
- This way, the keyboard callbacks are called even if the page has not
the focus, hence the user doesn't have to guess that they have to click
on the page which is a bit painful especially in Ink mode.
- Add two keyboard shortcuts to commit a Freetext editor (ctrl+enter and
escape).
In the referenced PDF document the fonts have /CIDToGIDMap-entries that cannot be loaded. Hence, only when `ignoreErrors` is set, we'll now ignore these corrupt /CIDToGIDMap-entries and fallback to simply assume that no such data is available.
Given that this is *clearly* a case of a corrupt PDF document, there's no guarantee that this will "fix" things in the general case since a /CIDToGIDMap may be *required* in order for some composite fonts to render correctly. However, attempting to render *something* is surely better than skipping a font altogether.
- In the annotationEditorLayer, reorder the editors in the DOM according
the position of the elements on the screen;
- add an aria-owns attribute on the "nearest" element in the text layer
which points to the added editor.
- in using the global clipboard, it'll be possible to copy from a
pdf and paste in an other one;
- it'll allow to edit a previously created annotation;
- copy the editors in the current page.
Previously, we had to set the #allowClick property by hand which was
a bit painful because it's easy to overlook one case or an other.
So with this patch a new editor (for now FreeText one only because the
Ink one is a bit different) is created on the first click if none is selected
on mousedown, else the first click will just commit the data and then the
second will creater a new editor.
The problem is clearly visible when the thickness is at max.
It's mainly because the thickness was not taken into account when
translating the div but it was when the line is drawn on the canvas.
Note that these cases, which are all in older code, were found using the [`unicorn/no-for-loop`](https://github.com/sindresorhus/eslint-plugin-unicorn/blob/main/docs/rules/no-for-loop.md) ESLint plugin rule.
However, note that I've opted not to enable this rule by default since there's still *some* cases where I do think that it makes sense to allow "regular" for-loops.
Note how we currently throw a "raw" Error, which is problematical since all of the `PartialEvaluator.loadFont` call-sites expect a Promise to be returned. Furthermore, this also means that we don't benefit from the fallback code-path that now exists below.
*Please note:* Unfortunately I don't have a test-case that fails without this patch, since it's something I happened to notice when reading the code while working on another patch.
Previously it was created only on mouseover event but on a touch screen
there are no fingerover event...
The idea behind creating the ink editor on mouseover was to avoid to have
a canvas on each visible page.
So now, when the editor is created, the canvas has dimensions 1x1 and
only when the user starts drawing the dimensions are set to the page ones.
We want to avoid adding regular `id`s to xfaLayer-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 DOM-elements directly if needed. *Please note:* This is basically the xfaLayer-equivalent of PR 15057.
- and because of rounding errors it led to slightly resize again and again
the ink container;
- when zooming the size is changing but not the ratio, so in this case we
don't need to change the dimension of the container.
`HTMLSectionElement` is not part of the DOM, so the generated typescript definitions contain a non-existing type.
HTML Section elements have to be handled as simple `HTMLElements`.

[jsdoc] failing typescript builds - wrong type
Rather than including all of this external code in the PDF.js repository, we should be using the npm package instead.
Unfortunately this is slightly more complicated than you'd hope, since the `fit-curve` package (which is older) isn't directly compatible with modern JavaScript modules.
In particular, the following cases needed to be considered:
- For the development viewer (i.e. `gulp server`) and the unit-tests, we thus need to build a fitCurve-bundle that can be directly `import`ed.
- For the actual PDF.js build-targets, we can slightly reduce the sizes by depending on the "raw" `fit-curve` source-code.
- For the Node.js unit-tests, the `fit-curve` package can be used as-is.
- this way the context menu in Firefox can take into account what we
have in the clipboard, if an editor is selected, ...
- when the user will click on a context menu item, an action will be
triggered, hence this patch adds what is required to handle it;
- some tests will be added in the Firefox' patch.
This extends PR 13461, by also building a fallback bounding box for Type3 fonts that contain a much too small /FontBBox-entry.
*Please note:* While this patch improves things overall, copy-and-pasting still doesn't work perfectly for this document. In particular the lowercase letter "c" cannot be selected/copied, however this can be reproduced in both Adobe Reader and PDFium (in Google Chrome) too, which is caused by a lack of proper /ToUnicode-data in the PDF document.
