In general we neither want, nor can, support arbitrary `Launch` actions. But in practice, all the cases we've seen so far just contains relative URLs to other PDF files. Building on PR 7689, we can thus at least support basic `Launch` actions.
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.
Note that this will automatically reject any relative URL.
To make the API more useful to consumers, URLs that are rejected will be available via the `unsafeUrl` property in the data object returned by `PDFPageProxy_getAnnotations`.
The patch also adds a bit more validation of the data for `Named` actions.
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.
This requires the `run-sequence` dependency because Gulp does not have a
way to run sequences of tasks inside a Gulp task. Gulp 4.0 will have
support for this, but until that is released this is the recommended way
to implement it.
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.

Each well-formed SVG image has the following structure:
SVG element
- Definitions element
- Root group
- Other group 1
- ...
- Other group n
This patch factors out initialization code into a private method in such
as way that the creation of this structure is clear from the code. The
root group is the replacement for the parent group from before. We need
this group as we cannot apply the viewport transform on the SVG element
itself (this caused issues in Chrome). If other code appends groups to
the SVG image, in reality it is appending those groups to the root
group, but this detail is abstracted away by this patch.
This patch ensures that we only create transformation groups when it is
actually required and that we re-use transform groups as much as possible.
It reduces the number of transform groups for the Tracemonkey paper from
2790 to 1271, thereby making the DOM much lighter and rendering/scrolling
smoother. Moreover, it simplifies the code and prevents duplication.
Finally, we issue a warning when an unimplemented graphic state is
encountered. Before, this was ignored silently, making debugging harder.
This patch:
- resolves a warning in the console about missing character encoding;
- makes the viewer use the same background color and PDF file as the
regular viewer;
- simplifies the example to bring it more in line with the other
examples.
Let `Parser_makeFilter` pass in the `DecodeParms` data to various image `Stream`s, instead of re-fetching it in various `[...]Stream.prototype.ensureBuffer` methods
In `Parser_filter` the `DecodeParms` data is fetched and passed to `Parser_makeFilter`, where we also make sure that a `Ref` is resolved to a direct object.
We can thus pass this along to the various image `Stream` constructors, to avoid the current situation where we lookup/resolve data that is already available.
Note also that we currently do *not* handle the case where `DecodeParms` is an Array entirely correct in the various image `Stream`s, and this patch fixes that for free.
While the array argument to TJ should only contain strings and numbers, other
unfortunate items are found in PDFs in the wild, e.g.:
[(Grandes) 0.0 Tc
-250.0 (Client\350les,) 0.0 Tc
-250.0 (Financements) 0.0 Tc
-250.0 (et) 0.0 Tc
-250.0 (March\351s) ] TJ
getOperatorList already properly ignores any non-string, non-numeric values in
TJ arrays; without this patch to getTextContent, returned text items can have
NaN widths due to calculations being applied to those non-numeric values.
