Re: [Inkscape-devel] Image resampling [PATCH 0/6]
2012/11/24 Søren Sandmann <sandmann@...2931...>:
Hi,
Reviewing the supersampling patch here:
http://cgit.freedesktop.org/~ajohnson/pixman/log/?h=supersampling
I wasn't happy with either the performance and image quality, and I realized that the whole supersampling approach just isn't going to fly. Since I told people to do it that way, I apologize for that. The approach advocated by Bill Spitzak in the various downsampling threads of computing a convolution kernel up front, is the much better way to go. To make up for being misleading, the following patches implement comprehensive support for high-quality image scaling filters.
This is extremely awesome.
Regards, Krzysztof

Wow. That's really great news. It not only means one less blocker for inkscape 0.49 when it's released, but a fix for several gnome applications that were released anyway and sport an fugly downscaling (like evince, eye of gnome and others).
Gez.

The Cairo side still needs to be done though, so the problem is not yet solved, but the hard part has been completed.

I read that again and this is probably unclear. What I meant was that these patches implement correct downscaling in Pixman, but it's not accessible from Cairo yet.

Ah, ok. I got overexcited Anyway it's great news. :-)
I've followed this on the Cairo list and don't recall discussion of anyone actually working on this. It was just mentioned that it needed to be done.

Any idea when this will be available from Cairo ?
