How to use resizer in that the size is zero? That means the resize didn't see but works

2014-07-21 Thread Yonggang Luo
Because our UI are customized by ourself, So we need the width of resize to be 
'zero', (Zero doesn't mean truely zero, just we can not see it).

If you want the background clipped to the rounded border, and the 
rounded border to be on the root, then you can't do that.

Re: Studying Lossy Image Compression Efficiency, July 2014

2014-07-21 Thread Bryan Stillwell
One option that I haven't seen compared is the combination of JPEG w/ packJPG 
(http://packjpg.encode.ru/?page_id=17).  packJPG can further compress JPEG 
images another 20%+ and still reproduce the original bit-for-bit.

More details on how this is done can be found here:

http://mattmahoney.net/dc/dce.html#Section_616

To me it seems that JPEG+packJPG could be competitive or exceed HEVC-MSP on 
bits/pixel.

Form autofill + pushState

Does Firefox autofill Forms that were submitted using AJAX + pushState? 
Chrome plans to add support: 
https://code.google.com/p/chromium/issues/detail?id=43219#c39


and I want to know where Firefox stands on this issue. Do you plan to 
add such support? Have you already?


In your opinion, what is the best way to submit forms using AJAX without 
losing autofill support?

Right, because of background propagation to the viewport.  The spec

Linux Off-main-thread compositing (OMTC) enabled

2014-07-21 Thread Christopher Lord
Hi all,

Earlier today, I pushed the patch that enables OMTC on Linux[1][2], meaning we 
will now have OMTC enabled on all platforms. Linux is slightly different to 
other platforms, as we currently have hardware-accelerated layers disabled. 
This means it uses the BasicCompositor, which before this point, is not hugely 
well-tested. Please keep an eye out for any visual regressions, and we'll do 
our best to stay on top of them.

There is an expected, marked performance regression in some tests when enabling 
this feature. This is mainly due to measurements not taking into account the 
asynchronicity of X (and the omtc path having a couple more XSync's) - Some of 
these results are false, and so the new numbers don't actually represent as 
much of a regression as you would initially think. It's worth noting that Linux 
numbers are now more in line with our other platforms.

Some of the performance regression is real, due to unoptimised display paths in 
BasicCompositor[3][4]. These will eventually be resolved, as I believe we'll 
require this path on other platforms.

There are also performance wins; Scrolling performance is improved and OMTC 
allows us to have asynchronous video playback, which is also a huge 
improvement. Canvas performance also improves (for some unknown reason...) The 
gfx team has discussed this at length and we believe the performance trade-off 
is very much worth it, especially considering the things OMTC allows us to 
enable/do in the future.

If you have issues, me, Bas Scouten and Nicolas Silva should be able to address 
them.

Brace yourselves!

It might be useful in Firefox OS development: we routinely re-compress

Here's what I tested with:

data:text/html,


open('data:application/vnd.mozilla.xul+xml,xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"; 
width="400" height="200" style="background:red;border:1px solid 
black;border-radius:20px"/>', '', 'chrome')

Setting a border radius on the root element is not supported.


In XUL, right?  Works fine in HTML.

Setting a border radius on the root element is not supported. You'll 
need to make the window element transparent and add a wrapper element 
(like ) that you set the border radius on.
