In the `RenderPageRequest` handler in `worker.js`, we attempt to print an `info` message containing the rendering time and the length of the operator list. The latter is currently broken (and has been for quite some time), since the `length` of an `OperatorList` is reset when flushing occurs.
This patch attempts to rectify this, by adding a getter which keeps track of the total length.
*Follow-up to PR 6546.*
If rendering has already started when the document is destroyed, then `this.pageCache[data.pageIndex]` may already have been cleared when the `StartRenderingPage`/`RenderPageChunk` messages are recieved in `api.js`, which results in `TypeError`s being thrown.
We should never actually try to execute `paintXObject` in canvas.js, but in some cases where we fail to parse the PDF file correctly it can happen. Currently this will potentially cause an entire page to fail to render, which seems suboptimal.
With this patch, we will instead continue rendering with a warning that things might not work correctly.
`operatorList.addOp` adds the arguments to the list which is then
passed as-is by postMessage to the main thread. But since we don't
parse these operations, they are raw PDF objects and may therefore
cause a serialization error.
This is a conservative patch, and only affects operators which are
known to be unsupported. We should ignore all unknown operators,
but I haven't really looked into the consequences of doing that.
Fixes#6549
The standard viewer implicitly depends on the `onPassword` and `onProgress` callbacks, in order to open password protected PDF files, respectively to report file loading progress. We currently have no unit-tests for this functionality, which seems unfortunate; hence this patch.
*Please note:* Rather than adding more unit-tests to `api_spec.js`, I slightly extended/reworked two existing tests. Specifically for the password test, this *does not* really change what we actually test, just how the test is done.
In PR 6485 I somehow missed to account for the case where `xref` is undefined. Since a dictonary can be initialized without providing a reference to an `xref` instance, `Dict_getArray` can thus fail without this added check.
Replaces `PDFJS.openExternalLinksInNewWindow` with a more generic configuration option.
*Note:* `PDFJS.openExternalLinksInNewWindow = true;` is equal to `PDFJS.externalLinkTarget = PDFJS.LinkTarget.BLANK;`.
*This regressed in PR 5356.*
Rather than just backing out the offending code, this patch restores scrolling in PresentationMode by making the `overflow: hidden;` check optional and letting the callers that need it (e.g. `PDFFindController`) opt-in to use it.
