Directly use the hexadecimal representation, just like the
`AnnotationFlags`, to avoid calculations and to improve readability.
This allows us to simplify the unit tests for text widget annotations as
well.
This patch improves performance by avoiding unnecessary type
conversions, which also help the JIT for optimizations.
Moreover, this patch fixes issues with the div expansion code where
`textScale` would be undefined in a division. Because of the `dataset`
usage, other comparisons evaluated to `true` while `false` would have
been correct. This makes the expansion mode now work correctly for cases
with, for example, each glyph in one div.
The polyfill for `WeakMap` has been provided by @yurydelendik.
Currently the `isSpace` utility function is a member of `Lexer`, which seems suboptimal, given that it's placed in `core/parser.js`. In practice, this means that in a number of `core/*.js` files we thus have an *otherwise* completely unnecessary dependency on `core/parser.js` for a one-line function.
Instead, this patch moves `isSpace` into `shared/util.js` which seems more appropriate for this kind of utility function. Not to mention that since all the affected `core/*.js` files already depends on `shared/util.js`, this doesn't incur any more file dependencies.
This is required to be able to use it in the annotation display code,
where we now apply it to sanitize the filename of the FileAttachment
annotation. The PDF file from https://bugzilla.mozilla.org/show_bug.cgi?id=1230933 has shown that some PDF generators include the path of the file rather than the filename, which causes filenames with weird initial characters. PDF viewers handle this differently (for example Foxit Reader just replaces forward slashes with spaces), but we think it's better to only show the filename as intended.
Additionally we add unit tests for the `getFilenameFromUrl` helper
function.
Currently the `deprecated` message is using `warn`, meaning that it's possible to disable warnings about deprecated API usage through the `PDFJS.verbosity` setting.
I don't think that it should be possible to opt out of deprecation messages,[1] since it might mean that in a custom deployment of PDF.js these messages could be overlooked, leading to PDF.js being broken (seemingly without any warning) when updating to a future version.
Obviously this could be considered the responsibility of the people doing custom PDF.js implementations, but in order to reduce the support burden later on, it seems better to "annoy" people upfront.
Compared to various `info`/`warn`/`error` messages, `deprecated` messages should be very simple to get rid of -- just update the API usage and the message goes away!

[1] In e.g. Firefox it doesn't seem possible to prevent deprecation warnings from being displayed (in the Browser Console).
Re: issue 5089.
(Note that since there are other outline features that we currently don't support, e.g. bold/italic text and custom colours, I thus think we can keep the referenced issue open.)
The Firefox addon currently fails with:
```
SyntaxError: missing ; before statement pdf.js:1692:12
TypeError: PDFJS.shadow is not a function viewer.js:6228:12
```
Apparently some PDF files can have annotations with `URI` entries ending with `null` characters, thus breaking the links.
To handle this edge-case of bad PDFs, this patch moves the already existing utility function from `ui_utils.js` into `util.js`, in order to fix those URLs.
Fixes 6832.
Now we have a full list of all possible annotation types and the
numbering corresponds to the order in the specification. Not only is
this more consistent and complete, it also prevents having to add these
constants when a new annotation type is implemented.
Additionally fix an issue where a regular Widget annotation would not
have `data.annotationType` set. It was only set for a
TextWidgetAnnotation, but instead move it to the base Widget annotation
class to add it for all Widget annotations (since TextWidgetAnnotation
inherits from WidgetAnnotation it will have it too).
This patch:
- Updates the JSDoc comment in `api.js`, to more clearly point out that `PDFJS.openExternalLinksInNewWindow` is deprecated, and explains what to use instead.
- Changes the `warn`, in `isExternalLinkTargetSet()`, to use the new `deprecated` function instead. Also updates the message with more detailed information about what to use instead.
- Changes the pre-processor tag to ensure the deprecation warning is seen in all build types where it could possibly matter (in case people are using `PDFJS.openExternalLinksInNewWindow` in e.g. custom-built extensions).
These changes were prompted by seeing http://stackoverflow.com/questions/33813373/pdf-js-how-to-open-hyperlinks-in-a-new-tab-window, since it seems to me that the current comments/warnings might not be worded well enough.
This patch makes it possible to set and get all possible flags that the PDF specification defines. Even though we do not support all possible annotation types and not all possible annotation flags yet, this general framework makes it easy to access all flags for each annotation such that annotation type implementations can use this information.
We add constants for all possible annotation flags such that we do not need to hardcode the flags in the code anymore. The `isViewable()` and `isPrintable()` methods are now easier to read. Additionally, unit tests have been added to ensure correct behavior.
This is another part of #5218.
Replaces `PDFJS.openExternalLinksInNewWindow` with a more generic configuration option.
*Note:* `PDFJS.openExternalLinksInNewWindow = true;` is equal to `PDFJS.externalLinkTarget = PDFJS.LinkTarget.BLANK;`.
Serialize errors to make sure that the callback is still invoked when
an error is thrown.
Firefox:
"DataCloneError: The object could not be cloned."
Chrome:
"DataCloneError: Failed to execute 'postMessage' on 'WorkerGlobalScope': An object could not be cloned."
For passwords where the encoding already is correct, the conversion is a no-op.
Also, since `encodeURIComponent` might throw, we need to make sure that we handle that case too.
Fixes 6010.
