Please note that while the current code works, both in the viewer and the unit-tests, it can leave the `WorkerTransport._passwordCapability` Promise in a pending state.
In the `PasswordRequest` handler, in src/display/api.js, we're returning the Promise from a `capability` object (rather than just a "plain" Promise). While an error thrown anywhere within this handler was fortunately enough to propagate it to the Worker side, it won't cause the Promise (in `WorkerTransport._passwordCapability`) to actually be rejected.
Finally note that while we're now catching errors in the `PasswordRequest` handler, those errors are still propagated to the Worker side via the (now) rejected Promise and the existing `return this._passwordCapability.promise;` line.
This prevents warnings about uncaught Promises, with messages such as "Error: Worker was destroyed during onPassword callback", when running the unit-tests both in browsers *and* in Node.js/Travis.
This should provide a better out-of-the-box experience when using PDF.js in a Node.js environment, since it's missing native support for both `@font-face` and `Image`.
Please note that this change *only* affects the default values, hence it's still possible for an API consumer to override those values when calling `getDocument`.
Also, prevents "ReferenceError: document is not defined" errors, when running the unit-tests in Node.js/Travis.
This avoids the initialization of, potentially thousands of, unnecessary `Stream` objects, by getting the required number of bytes directly instead.
Given the special behaviour, when `length === 0`, of the `getBytes`/`skip` methods, it's also necessary to handle that particular case to prevent errors when encountering empty CharStrings.
This commit adds `scrollModeOnLoad` and `spreadModeOnLoad` preferences
that control the default viewer state when opening a new document for
the first time.
This commit also contains a minor refactoring of some of the option UI
rendering code in extensions/chromium/options/options.js, as I couldn't
bear creating two more functions nearly identical to the four that
already existed.
This builds on the scrolling mode work to add three buttons for joining
page spreads together: one for the default view, with no page spreads,
and two for spreads starting on odd-numbered or even-numbered pages.
Prior to this commit, if the vertical scroll bar is absent and the horizontal
scroll bar is present, a link to a particular point on the page which should
induce a horizontal scroll did not do so, because the absence of a vertical
scroll bar meant that the viewer was not recognized as the nearest scrolling
ancestor. This commit adds a check for horizontal scroll bars when searching
for the scrolling ancestor.
In `rasterizeAnnotationLayer` we load the source CSS files directly, so
these are not processed by Autoprefixer. Since the prefixed rules have
now been removed from the source CSS files, we must manually provide one
prefixed rule that Chrome needs in the overrides CSS file for checkbox
and radio button rendering to work in the reference tests.
