fa46b73c47 Better spacing in text layer. 2015-11-02 08:54:15 -06:00

487ba9065a Fail gracefully, and with a notification, if paintXObject is encountered in canvas.js 
We should never actually try to execute `paintXObject` in canvas.js, but in some cases where we fail to parse the PDF file correctly it can happen. Currently this will potentially cause an entire page to fail to render, which seems suboptimal.
With this patch, we will instead continue rendering with a warning that things might not work correctly.

2564827503 Fix text spacing with vertical fonts (#6387) 
According to the PDF spec 5.3.2, a positive value means in horizontal,
that the next glyph is further to the left (so narrower), and in
vertical that it is further down (so wider).
This change fixes the way PDF.js has interpreted the value.

063ca95f5f Remove TryCatch in canvas fill 
As verified by @Rob--W, the evenodd fill rule works correctly in all supported browsers. This now allows optimization by JS engines.

This fixes #5458

cfd5a64df5 Ensure that the clipping path is reset when the state is restored (issue 6413) 
According to the specification, see `NOTE 2` in http://www.adobe.com/content/dam/Adobe/en/devnet/acrobat/pdfs/PDF32000_2008.pdf#G7.3882161, it appears that we should ensure that the clipping path is reset when the restore (`Q`) operator is encountered.

Fixes 6413.

a64536901a Increase the font weight used for non-embedded ArialBlack fonts 
Currently non-embedded ArialBlack fonts are not rendered bold enough, compared to e.g. Adobe Reader.
The issue is that we set the font weight to `bolder`, but since that is actually relative to the font weight of the parent, the result is that there's no practical difference from just using `bold`.

This patch attempts to address that, by explicitly setting the font weight to the maximum value instead (see https://developer.mozilla.org/en-US/docs/Web/CSS/font-weight).

*Note:* I expect one test "failure" in `issue5801`, which in this case is an improvement, since that PDF file uses ArialBlack.

6eb9e6a6a4 Fix flaw in mozCurrentTransform polyfill 
Set transformation matrix in (polyfilled) mozPrintCallback when a scale
is applied. Removed _scaleX and _scaleY in favor of _transformMatrix to
emphasize that the caller MUST ensure that the state of the matrix is
correct before `addContextCurrentTransform` is called.

ceffeab1de Use 3 param method for converting r,g,b into css string. 
This avoids creation of temporary arrays to pass them into the util
method. Also using "arguments" is more expensive then passing in 3
parameters.
