Note that in `FIREFOX/MOZCENTRAL/CHROME` builds of the standard viewer the `docBaseUrl` parameter will be set by default, since in that case it makes sense to use the current URL as a base.
For the `GENERIC` viewer, or the API itself, it doesn't make sense to try and set the `docBaseUrl` by default. However, custom deployments/implementations may still find the parameter useful.
This not only reduces code duplication, but it also allow us to easily support the same kind of URLs we currently do for Link annotations in the Outline as well.
The outline toggle button has a feature where it can be double-clicked
to expand/collapse all items shown therein. Although this is described
in the FAQ, can go potentially unnoticed. This, however, being a useful
feature, advertise on the tool tip itself.

When opening a PDF file that triggers the browser fallback bar in the Firefox addon/built-in version, e.g. http://web.archive.org/web/20110918100215/http://www.irs.gov/pub/irs-pdf/f1040.pdf (with forms *disabled*), and then reloading the document an error can be thrown.
The reason is that displaying the fallback bar triggers 'resize' events, and they can arrive *before* the viewer has had a chance to run all the necessary initialization code.
If interactive forms are enabled, then the display layer takes care of
rendering the form elements. There is no need to draw them on the canvas
as well. This also leads to issues when values are prefilled, because
the text fields are transparent, so the contents that have been rendered
onto the canvas will be visible too.
We address this issue by passing the `renderInteractiveForms` parameter
to the render task and handling it when the page is rendered (i.e., when
the canvas is rendered).
There's really no good reason to attempt to adjust the `max-height` of the `SecondaryToolbar` when it's not visible, so let's not do that anymore.
Also, we can listen for the `resize` event in `SecondaryToolbar`, to avoid having to manually call the `max-height` adjust function from various event handlers in `app.js`. Please note that by always adjusting the `max-height` when the toolbar is opened we no longer need the `localized` event, since it was mainly used to set a correct inital `max-height` value.
Please note that this is a hack, but I think that it should be OK for now to atleast get the preference landed. Refer to the code comment for further information.
Re: issue 7584 and PR 7586.
This patch is the first step towards implementing support for
interactive forms (AcroForms). It makes it possible to render text
widget annotations exactly like Adobe Reader/Acrobat.
Everything we implement for AcroForms is disabled by default using a
preference, mainly because it is not ready to use yet, but has to
implemented in many steps to avoid complexity. The preference allows us
to work with the code while not exposing the behavior by default. Mainly
storing entered values and printing them is still absent, which would be
minimal requirements for enabling this by default.
When clicking on the `pageNumber` input, or when using the keyboard shortcut <kbd>Ctrl</kbd>+<kbd>Alt</kbd>+<kbd>G</kbd>, the element isn't just focused but its contents is actually *selected* so that the user doesn't need to clear the input before entering a new `pageNumber`.
However, the `GoToPage` named action is only using `focus`, so let's change this to be consistent.
The following document can be used for testing: http://www2.informatik.uni-freiburg.de/~frank/ENG/beamer/example/Beamer-class-example1.pdf#zoom=page-fit
[screeenshot]
1. Expanding divs to improve text selection. (Yury)
2. Adding enhanceTextSelection as an option.
3. Moving feature functionality from text_layer_builder.js to text_layer.js.
4. Added expandTextDivs method to only load expanded divs on first click, and only show on subsequent clicks
In the `zoom{In, Out}` functions in `PDFViewerApplication`, we prevent the zoom value from becoming smaller/larger than `MIN_SCALE/MAX_SCALE`.
However, if the user sets the zoom level through the hash parameter the zoom buttons might not be correctly disabled; try http://mozilla.github.io/pdf.js/web/viewer.html#zoom=10.
Note that this issue has been present since "forever", but given that the solution is so simple I think that we should just fix this. (I'm also fixing a stupid typo I previously made in the JSDoc comment.)
With the viewer code now being split into various components/files, having an obsolete comment in `PDFViewer` that references thumbnails despite there being no other mentions of them in the entire file seems strange.
*Note:* This comment is simply a left-over from older versions of PDF.js, where the *entire* default viewer code was placed in just one file (and where we unconditionally created thumbnails, regardless whether they were visible or not).
There are PDF generators which create destinations with e.g. too large top values, which cause the wrong page to be scrolled into view because the offset becomes negative.
By ignoring negative offsets, we can prevent this issue, and get a similar behaviour as in Adobe Reader.
However, since we're also using `PDFViewer_scrollPageIntoView` in more cases than just when links (in the document/outline) are clicked, the patch adds a way to allow the caller to opt-out of this behaviour.
In e.g. the following situations, I think that we still want to be able to allow negative offsets: when restoring a position from the `ViewHistory`, when the `viewBookmark` button is used to obtain a link to the current position, or when maintaining the current position on zooming.
Rather than adding another parameter to `PDFViewer_scrollPageIntoView`, I've changed the signature to take an parameter object instead. To maintain backwards compatibility, I've added fallback code enclosed in a `GENERIC` preprocessor tag.
Fixes https://bugzilla.mozilla.org/show_bug.cgi?id=874482.
With PR 7502 we no longer dispatch an event when the `val` is out of bounds, so to better communicate why nothing happens this patch logs an error in that case (similar to the logging of errors when trying to set an invalid scale).
The way that the default viewer is currently implemented, means that e.g. keyboard short-cuts could trigger the new error. Hence this patch also adds the necessary validation code, both to `app.js` and `pdf_link_service.js` to prevent unnecessary errors.
