With the recently added OpenJPEG no-wasm fallback we need to send the `wasmUrl` option to the worker-thread *regardless* of the value of the `useWorkerFetch` option, since the fallback won't work if we don't have a URL to `import` it from.
For consistency the code is re-factored to always send the factory-urls to the worker-thread, and simply check the `useWorkerFetch` option there instead.
Also, as a follow-up to PR 19525, introduce a new `useWasm` option that can be used in e.g. browser-tests to forcibly disable WebAssembly usage.
This patch fixes an issue when pasting: an exception was thrown when pasting.
And while writing the test and comparing the paths in the svg, I found a difference
which is fixed thanks to call to the right constructor (to take into account the inheritance)
in inkdraw.js
When rendering big PDF pages at high zoom levels, we currently fall back
to CSS zoom to avoid rendering canvases with too many pixels. This
causes zoomed in PDF to look blurry, and the text to be potentially
unreadable.
This commit adds support for rendering _part_ of a page (called
`PDFPageDetailView` in the code), so that we can render portion of a
page in a smaller canvas without hiting the maximun canvas size limit.
Specifically, we render an area of that page that is slightly larger
than the area that is visible on the screen (100% larger in each
direction, unless we have to limit it due to the maximum canvas size).
As the user scrolls around the page, we re-render a new area centered
around what is currently visible.
Currently we modify the EXIF-block in place, which may end up "breaking" the JPEG-data of the original PDF document since e.g. saving it from the viewer no longer contains the real EXIF-block.
Hence the EXIF-block replacement is moved into the `JpegStream` class, such that we can copy the data before doing the replacement.
During the XRef stream parsing we're attempting to lookup an entry that hasn't yet been found, since parsing is currently running, and given that we'd also cache free/missing XRef entries we'd then return an incorrect value during normal PDF parsing.
The simplest solution here is to just not cache free/missing XRef entries, since a properly generated PDF document shouldn't be trying to access objects it doesn't contain.
Furthermore, the amount of "extra" parsing now needed for such XRef entries shouldn't be significant enough to be an issue.
It fixes#19505.
We were invaliding throwing actions (in setting event.rc to false) and all the event process was stopped.
Now we're just dumping the exception in the console: the action is skipped and event.rc is not set
else the input fields aren't updated wit KeyStroke actions.
Currently this rule is disabled in a number of spots across the code-base, and unless absolutely necessary we probably shouldn't disable linting, so let's just update the code to fix all the outstanding cases.
If either of the factory-urls are missing or invalid, the fallback value would currently become `useWorkerFetch === null`.
While that is obviously a falsy value, which means that the code still works as intended, we should ensure that this is consistent.
- Use `TypedArray.prototype.set()` rather than a manual loop when building the `key`.
- Use an existing local variable to avoid re-computing the length of the `encryptionKey`.
Rather than modifying the "raw" dimensions of the page, we'll instead apply the `userUnit` as an *additional* scale-factor via CSS.
*Please note:* It's not clear to me if this solution is fully correct either, or if there's other problems with it, but it at least *appears* to work.
---
With these changes, the following CSS variables are now assumed to be available/set as necessary: `--total-scale-factor`, `--scale-factor`, `--user-unit`, `--scale-round-x`, and `--scale-round-y`.
Given that most inferred links will overlap existing LinkAnnotations, creating a lot of unused `borderStyle` objects seem unnecessary.
Hence we can move that into the `AnnotationLayer.prototype.addLinkAnnotations` method instead, which also allows us to slightly reduce the API-surface.
Currently we have three separate and virtually identical message handlers for this data, which can easily be combined into a single message handler instead.
Automatically detect links in the text content of a file and automatically
generate link annotations at the appropriate locations to achieve
automatic link detection and hyperlinking.
