- when binding (after parsing) we get a map between some template nodes and some data nodes;
- so set user data in input handlers in using data node uids in the annotation storage;
- to save the form, just put the value we have in the storage in the correct data nodes, serialize the xml as a string and then write the string at the end of the pdf using src/core/writer.js;
- fix few bugs around data bindings:
- the "Off" issue in Bug 1716980.
This patch provides an overall simpler *and* more consistent way of handling the `viewport` parameter during printing of XFA forms, since it's now again guaranteed to always be an instance of `PageViewport`.
Furthermore, for anyone attempting to e.g. implement custom printing of XFA forms this probably cannot hurt either.
*Sorry about the churn here, since the change that I made in PR 13516 was not very smart.*
With the current code, it's now *impossible* for a user to actually control the `useSystemFonts` option manually. To prevent outright breakage we obviously still need to default to setting `useSystemFonts = false` when `disableFontFace === true`, however that should be possible for an API consumer to override.
Note, this only really fixes Radial/Axial shading patterns with masks.
I'm guessing tiling patterns and mesh patterns would also be broken
if applied like the test pdf. Hopefully I'll have some time to make
test cases for the other shadings.
Fixes#13372
This is first of all consistent with all of the other (similar) factories, and secondly it will also simplify a future addition of a corresponding `NodeSVGFactory` (if that's ever deemed necessary).
- Some js files contain scale factors for each glyph in order to rescale Liberation to have a final font with the correct width.
- A lot of XFA have some containers where their dimensions are based on their text content, so using default font from browser can lead to an almost unreadable pdf.
Given that there's no fallback on the worker-thread, it shouldn't be necessary to initialize `CMapReaderFactory`/`StandardFontDataFactory` when `useWorkerFetch = true` is set.
Slightly unrelated, but this patch also ensures that the `useSystemFonts` default value only does the `isNodeJS` check in builds where that's actually necessary.
At this point in time, the `apiCompatibilityParams` is essentially unused with the sole exception of the `disableFontFace` handling for Node.js environments.
Given that `isNodeJS` is a constant now (originally it was a function), we can simply set the correct fallback value for `disableFontFace` directly in the API and clean-up the code a bit here.
This patch uses the new option added in PR 12726 to *also* allow fetching binary CMap data directly in the worker-thread in browsers.
Given that these changes remove the need to transfer data between threads for the default (browser) use-case, we can also revert the changes in PR 11118 since that simplifies the overall implementation.
Given that these factories are being used in *different* files, for Browser respectively Node.js implementations, it seems reasonable to move them into their own file instead.
- some elements weren't displayed because their rotation angle was not taken into account;
- fix box model (XFA concept):
- remove use of outline;
- position correctly border which isn't part of box dimensions;
- fix margins issues (see issue #13474).
- move border on button instead of having it on wrapping div;
Generally, in the `src/display/` folder, we utilize `DOMSVGFactory` rather than manually creating an SVG-element; hence let's do the same thing in `src/display/pattern_helper.js` as well.
While this prevents the error which is currently thrown by the `assert` in the `DOMSVGFactory.create` method, the pattern still doesn't actually render (visibly). However, in the interest of getting rid of some open issues, this patch should make (some) sense and there's already other issues about patterns in the SVG-backend,
Given that, as clearly [outlined in the FAQ](https://github.com/mozilla/pdf.js/wiki/Frequently-Asked-Questions#backends), the SVG-backend is *not* officially supported and that there's currently no development of it; this is probably the most that is reasonable to do here.
- the only goal of this patch is to be able to get synchronously the fake html when printing from firefox:
- in order to print we need to inject some html in beforeprint callback but we cannot block in waiting for all the pages.
- from a memory point of view: it doesn't change anything since the fake HTML is deleted in the worker;
- this way we don't break any assumptions.
- I thought it was possible to rely on browser layout engine to handle layout stuff but it isn't possible
- mainly because when a contentArea overflows, we must continue to layout in the next contentArea
- when no more contentArea is available then we must go to the next page...
- we must handle breakBefore and breakAfter which allows to "break" the layout to go to the next container
- Sometimes some containers don't provide their dimensions so we must compute them in order to know where to put
them in their parents but to compute those dimensions we need to layout the container itself...
- See top of file layout.js for more explanations about layout.
- fix few bugs in other places I met during my work on layout.
According to the specification, see https://web.archive.org/web/20210404042322if_/https://www.adobe.com/content/dam/acom/en/devnet/acrobat/pdfs/PDF32000_2008.pdf#G6.2384179, the keys of a NameTree/NumberTree should be ordered.
For corrupt PDF files, which violate this assumption, it's thus possible that trying to lookup a single entry fails.
Previously, in PR 10274, we implemented a fallback that only applies to the "bottom" node of a NameTree/NumberTree, which in general might not actually help for sufficiently corrupt NameTree/NumberTree data.
Instead we remove the current *limited* fallback from `NameOrNumberTree.get`, and defer to the call-site to handle this case explicitly e.g. by using `NameOrNumberTree.getAll` for data where that makes sense. For well-formed documents, these changes should *not* lead to any additional data fetching/parsing.
Finally, as part of these changes, the validation of named destination data is improved in the `Catalog` and a new unit-test is also added.
To get the maximum benefit from something like Prettier, you obviously don't want to disable the automatic formatting unless absolutely necessary. When we added Prettier there were a number of cases, mostly involving larger Arrays, which required disabling of the automatic formatting for overall readability and/or to not break inline comments.
With changes in Prettier version `2.3.0`, see [the release notes](https://prettier.io/blog/2021/05/09/2.3.0.html#concise-formatting-of-number-only-arrays-10106httpsgithubcomprettierprettierpull10106-10160httpsgithubcomprettierprettierpull10160-by-thorn0httpsgithubcomthorn0), there's now better formatting support for Arrays containing only numbers. Hence we can now remove a number of `// prettier-ignore` comments, and thus get the benefit of automatic formatting in (slightly) more of the code-base.
