This replaces `assert` calls with `throw new FormatError()`/`throw new Error()`.
In a few places, throwing an `Error` (which is what `assert` meant) isn't correct since the enclosing function is supposed to return a `Promise`, hence some cases were changed to `Promise.reject(...)` and similarily for `createPromiseCapability` instances.
Fix TypeError that occurs in colorspace.js on accidentally passing an 'Array' instead of 'TypedArray'
Changed getRgbItem(...) to getRgbBuffer(...) since this.lookup has values in range[0, 255] whereas getRgbItem(...) expects those to be in range [0, 1]
Revert changes for IE9 compatibility
Looking at the blame, it seems that this typo was present even before PR 700 (almost six years ago).
The result of using `'num'`, rather than the *correct* `'numPages'` string, is that the `Catalog.numPages` getter isn't actually being shadowed.
Note that the PageMode, as specified in the API, will only be honoured when either: the user hasn't set the `sidebarViewOnLoad` preference to a non-default value, or a non-default `sidebarView` entry doesn't exist in the view history, or the "pagemode" hash parameter is included in the URL.
Since this is new functionality, the patch also includes a preference (`disablePageMode`), to make it easy to opt-out of this functionality if the user/implementor so wishes.
- Mark the test as async, and don't swallow exceptions.
- Fix the DOMElement polyfill to behave closer to the actual getAttributeNS
method, which excludes the namespace prefix.
Add UI for the cursorToolOnLoad pref in the UI of the Chrome extension.
Add logic to migrate the enableHandToolOnLoad pref to cursorToolOnLoad.
For past values in the mutable extension storage area:
1. If enableHandToolOnLoad=true, save cursorToolOnLoad=1.
2. Remove enableHandToolOnLoad.
For the managed extension storage, which is immutable since it is based
on administrative policies, use the following logic:
1. If enableHandToolOnLoad=true and cursorToolOnLoad=0 (default).
set cursorToolOnLoad=0 and assume enableHandToolOnLoad=false.
2. As usual, managed preferences can (and will) be overridden by the user.
The first migration logic is in extensions/chromium/options/migration.js
and can be removed after a few months / less than many years.
The second migration logic is in web/chromecom.js, and should be kept
around for a long while (many years).
The need for this migration logic arises from the change by:

* Check for undefined
new URL(file, window.location.href) throws the following error in IE11 + iPad Safari:
Unable to get property 'replace' of undefined or null reference
* Adapting previous change to pdf.js code standards
Added curly braces
* Moved check for undefined above try/catch
According to the PDF specification, please see http://www.adobe.com/content/dam/Adobe/en/devnet/acrobat/pdfs/PDF32000_2008.pdf#G6.2394361, if an Adobe JPEG marker is present it should always take precedence. This even seem to be consistent with the existing comment that is present in the code.
Hence it seems reasonable to interpret `transformCode === 0` as no color conversion being necessary.
Fixes the rendering of page 1 in `issue-4926` (from the test-suite), when the built-in `src/core/jpg.js` image decoder is used.
Use the environment's zlib implementation if available to get
reasonably-sized SVG files when an XObject image is converted to PNG.
The generated PNG is not optimal because we do not use a PNG predictor.
Futher, when our SVG backend is run in a browser, the generated PNG
images will still be unnecessarily large (though the use of blob:-URLs
when available should reduce the impact on memory usage). If we want to
optimize PNG images in browsers too, we can either try to use a DEFLATE
library such as pako, or re-use our XObject image painting logic in
src/display/canvas.js. This potential improvement is not implemented by
this commit
Tested with:
- Node.js 8.1.3 (uses zlib)
- Node.js 0.11.12 (uses zlib)
- Node.js 0.10.48 (falls back to inferior existing implementation).
- Chrome 59.0.3071.86
- Firefox 54.0
Tests:
Unit test on Node.js:
```
$ gulp lib
$ JASMINE_CONFIG_PATH=test/unit/clitests.json node ./node_modules/.bin/jasmine --filter=SVG
```
Unit test in browser: Run `gulp server` and open
http://localhost:8888/test/unit/unit_test.html?spec=SVGGraphics
To verify that the patch works as desired,
```
$ node examples/node/pdf2svg.js test/pdfs/xobject-image.pdf
$ du -b svgdump/xobject-image-1.svg
# ^ Calculates the file size. Confirm that the size is small
# (784 instead of 80664 bytes).
```
Do not directly export to global. Instead, export all stubs in domstubs.js and
add a method setStubs to assign all exported stubs to a namespace. Then replace
the import domstubs with an explicit call to this setStubs method. Also added
unsetStubs for undoing the changes. This is done to allow unit testing of the
SVG backend without namespace pollution.
Move the DEFLATE logic in convertImgDataToPng to a separate function.
A later commit will introduce a more efficient deflate algorithm,
and fall back to the existing, naive algorithm if needed.
`__pdfjsdev_webpack__` was used to skip evaluating part of an AST,
in order to not mangle some `require` symbols.
This commit removes `__pdfjsdev_webpack__`, and:
- Uses `__non_webpack_require__` when one wants the output to
contain `require` instead of `__webpack_require__`.
- Adds options to the webpack config to prevent "polyfills" for
some Node.js-specific APIs to be added.
- Use `// eslint-disable-next-line no-undef` instead of `/* globals ... */`
for variables that are not meant to be used globally.
Since we no longer, after PR 8555, allow changing the scale until the document is loaded, that hack is no longer necessary. Furthermore, no part of that event handling function needs to run unless a document is loaded.
The reason that this hack was initially added, is that previously the `ViewHistory` might be updated *before* `PDFViewerApplication.setInitialView` had run (in some cases leading to incorrect inital document scale). Since that is no longer possible, this is now dead code.
Don't allow setting various properties, such as `currentPageNumber`/`currentScale`/`currentScaleValue`/`pagesRotation`, before `{PDFViewer, PDFThumbnailViewer}.setDocument` has been called
