It fixes#19360.
Each glyph in the test case has a fill and a stroke pattern, so the current transform used
to scale the glyph outline must be the same.
In setting the stroke color to green, I noticed that the last outline contains some non-closed
subpaths, so when generating the glyph outline, every time we 'moveTo', we close the previous
subpath.
Currently we're not checking that the response is actually OK before getting the data, which means that rather than throwing an error we can get an empty `ArrayBuffer`.
To avoid duplicating code we can move an existing helper into `src/core/core_utils.js` and re-use it when fetching the JPX wasm-file as well.
In order to fix bug 1935076, we'll have to add a pure js fallback in case wasm is disabled
or simd isn't supported. Unfortunately, this fallback will take some space.
So, the main goal of this patch is to reduce the overall size (by ~93k).
As a side effect, it should make easier to use an other wasm file (which must export
_jp2_decode, _malloc and _free).
In the affected font the total number of mapping-entries is `1142348`, and no less than `997473` of them are duplicates.
Given that every duplicate causes a lot of Array elements to be moved this becomes extremely inefficient, which we can avoid by keeping track of seen `charCode`s and directly build the final mappings-Array instead.
Currently we re-implement a number of helper functions specifically for this code, which seems completely unnecessary since there's already general purpose ones available in the `src/core/core_utils.js` file.
The `/Root/AcroForm/Fields` array contains a "ridiculous" number of LinkAnnotations, which obviously makes no sense since those are not form fields.
To improve performance we'll thus ignore those when collecting the field objects.
There's a few cases where we're looping through the result of `Dict.prototype.getKeys` and then manually look-up the values, which after PR 19051 can be replaced with direct iteration instead.
From section [11.6.4.3 Mask Shape and Opacity](https://opensource.adobe.com/dc-acrobat-sdk-docs/pdfstandards/PDF32000_2008.pdf#G10.4848628) in the PDF specification:
- An image XObject may contain its own *soft-mask image* in the form of a subsidiary image XObject in the `SMask` entry of the image dictionary (see "Image Dictionaries"). This mask, if present, shall override any explicit or colour key mask specified by the image dictionary's `Mask` entry. Either form of mask in the image dictionary shall override the current soft mask in the graphics state.
As part of the changes in PR 4259, which landed over ten years ago, the `glyphNameMap` property on `Font`-instances was removed.
The reason that this didn't cause any bugs is that we always fallback on `getGlyphsUnicode`, and when using that data we also rely on `StandardEncoding`, hence we should just remove the unused parameter from the `Type2Compiled` constructor.
While [bug 1893645](https://bugzilla.mozilla.org/show_bug.cgi?id=1893645) was fixed some time ago now, it still shouldn't hurt to also assert that the `fontMatrix` is always valid when invoking the `compileGlyph` method.
Rather than having to manually implement the exception-handling for the "DocException" message, we can instead re-use (and slightly extend) the existing `wrapReason` function since that one already does what we need.
Furthermore, we can also simplify handling of the "PasswordRequest" message a little bit and again re-use the `wrapReason` function.
Finally, the patch makes the following smaller changes:
- Avoid needlessly re-creating exceptions in the `wrapReason` function.
- Use a slightly shorter parameter name in the `wrapReason` function.
- Remove the unused entries in the `CallbackKind`/`StreamKind` enumerations.
Without these calls we'll not actually wait for saving to complete when document destruction runs; compare with other `WorkerTask`-usage in this file.
While I cannot imagine that this has caused any problems for library users, the code is however not technically correct as-is.
- Use `this` in all scopes where that's possible, to avoid having to spell out `WorkerMessageHandler` everywhere.
- Inline the `isMessagePort` helper function, since there's only a single call-site.
- Use a static initialization block to move more code into the `WorkerMessageHandler` class itself.
This patch makes a clear separation between the way to draw and the editing stuff.
It adds a class DrawEditor which should be extended in order to create new drawing tools.
As an example, the ink tool has been rewritten in order to use it.
This is fairly old code, and by making the function `async` we can handle initialization errors "automatically" without the need for try-catch statements.
When iterating through `useCMap` the value is already available, without having to manually invoke the `lookup`-method.
While this will likely not affect performance in any noticeable way, it's nonetheless unnecessary to lookup an already available value twice.
This was previously attempted in PR 13371, but had to be reverted because of issues related to SystemJS (which has since been removed).
Also, while unrelated, shortens an existing conditional assignment.
Given that there are multiple issues with `ImageDecoder` in Chromium browsers, affecting both BMP and JPEG images, for now we (by default) disable that functionality there to avoid problems.
This also means that we can remove the previously added, and separate, `isChrome` API-option.
This allows end-users to forcibly disable `ImageDecoder` usage, even if the browser appears to support it (similar to the pre-existing option for `OffscreenCanvas`).
Flat config is the new config system used by ESLint 9.
To make the migration easier, they also added
flat config support to ESLint 8.
This commit migrates the various ESLint configs in the repository to use
the new system, **without** upgrading to ESLint 9 yet.
