This patch fixes a bug that caused incorrect curve shapes when an endpoint lies beyond the page boundaries. It adds a check for the endpoint's position, and if it is outside the page, the point is excluded from the shape's coordinates.
Steps to reproduce this in `master`:
1. Open https://mozilla.github.io/pdf.js/web/viewer.html
2. Use the "Open"-button (in the secondaryToolbar), or drag-and-drop, to load another PDF document.
3. Enable the highlight-editor.
4. Try to pick a new colour.
Note how it's no longer possible to change the default highlight-colour.
The reason for this is that we're only initializing the viewer-toolbar `ColorPicker` *once*, which doesn't work since every PDF document gets its own `AnnotationEditorUIManager`-instance. To address this we simply need to re-initialize the viewer-toolbar `ColorPicker`, and note that this patch won't affect the Firefox PDF Viewer.
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.
- Most of the these are only used in the `src/display/api.js` file, and this leads to slightly shorter code.
- A number of unit-tests need a `BaseCanvasFactory`-instance, however that one is available through the `PDFDocumentProxy`-instance nowadays.
- For other unit-tests the remaining necessary default Factory-definitions can be moved into the `test/unit/test_utils.js` file.
Given that we nowadays provide default Node.js versions of these Factory-parameters it no longer seems necessary to mention that environment specifically.
These old exceptions have a fair amount of overlap given how/where they are being used, which is likely because they were introduced at different points in time, hence we can shorten and simplify the code by replacing them with a more general `ResponseException` instead.
Besides an error message, the new `ResponseException` instances also include:
- A numeric `status` field containing the server response status, similar to the old `UnexpectedResponseException`.
- A boolean `missing` field, to allow easily detecting the situations where `MissingPDFException` was previously thrown.
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).
It lets the user make a pinch gesture with a finger on page with a drawing
and the second finger on an other page.
On mobile, it's pretty easy to be in such a situation.
It fixes#19239.
When the canvas isn't existing the editor has no image: it's fine because the editor is invisible.
Once it's made visible, the canvas is set when the annotation layer has been rendered.
This appears to have regressed in PR 13808, since it removed the `matrix`-entry from array returned by the `MeshShading.prototype.getIR` method *without* also updating the indexes in the `MeshShadingPattern` constructor.
Originally the code in this file was used in both the GENERIC and MOZCENTRAL builds, however that's no longer the case.
Hence we can now directly call `NetworkManager.prototype.request` and remove these old "helper" methods that only had a single call-site each.
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.
This bug only seems to reproduce in Google Chrome, since browsers apparently sort response headers differently.
When the issue occurs the "raw" response headers string looks like this:
```
content-length: 525404\r\ncontent-type: \r\n
```
and since we trim *any* leading/trailing white-space characters the "content-type" header isn't detected correctly, which thus leads to `new Headers(...)` throwing.
Hence we'll keep regular spaces at the end of the "raw" response headers string, while still removing all other kinds of trailing white-space characters.
*Note:* The response headers parsing was based on https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest/getAllResponseHeaders#examples
- it's now possible to start a drawing with a pen and use fingers to zoom
or scroll without interacting with the current drawing;
- it's now possible to draw with a finger and them zoom with two fingers.
When an editor is moved with the keyboard or in dragging it, it is moved in the DOM in order
to make screen readers happy. But this move is slightly postponed thanks to a setTimeout(..., 0).
The failures were very likely due to the fact that intermittently the DOM move was done in
the middle of the next key sequence which was making the move on screen failing.
It was due the resize observer which is removed thanks to this patch.
In order to reuse the dragAndDrop function in test, this patch slighty refactors it
in order to make it easier to use.
The `Path2D` glyph-objects are cached on the `FontFaceObject`-instance, so we can save a little bit of memory by removing the raw path-strings once they're no longer needed.
- Warn if the "regular" PDF.js build is used in Node.js environments, since that won't load any of the relevant polyfills.
- Warn if the `require` function cannot be accessed, since currently we're just "swallowing" any errors.
This helps ensure that loading errors are always handled correctly, and note that both `PDFNetworkStreamFullRequestReader` and `PDFNetworkStreamRangeRequestReader` already provided such a callback.
When a user deletes any number of annotations, they are notified of the action
by a popup message with an undo button. Besides that, this change reuses the
existing messageBar CSS class from the new alt-text dialog as much as possible.
This slightly shortens the code, in various `destroy`-methods, which cannot hurt.
Also, use pre-processor checks to simplify `PDFDocumentLoadingTask.destroy` in the Firefox PDF Viewer since the `PDFWorker.fromPort`-method isn't used there.
