This has already been mentioned, but I was wondering if we users could expect Cairo speed increases in the near future? I'm skeptical that the base performance of the Cairo library will improve much, but there has long been talk of a hardware-accelerated backend. Most recently, someone came up with one based on OpenVG (and its ShivaVG implementation using OpenGL and C). It's a long way from being part of base Cairo (or even released on its own). Of course, it would really help to optimize at a higher level (e.g. use caching to avoid re-rendering the same glyph thousands of times). I've also thought about using a vector-based API directly on top of OpenGL, like what Qt (and now the clutter project) has, but that's getting off-topic.

This has already been mentioned, but I was wondering if we users could expect Cairo speed increases in the near future? Some. As Michael Lawrence has already said, cairo speed is an issue and unlilkely to improve any time soon. And anti-aliasing takes some CPU time. What we can do is to reduce the information passing between R and the X server. I already have timer-based double buffering running (the same scheme as on Windows), and that helps a lot in the circumstances mentioned (lots of small symbols). There are some event-loop-interface issues to sort out before it get committed to R-devel. type=nbcairo is likely to be faster in your example, but not as fast as the buffered device planned for 2.8.0. The X11 server does make quite a difference -- I am running fairly decent Nvidia cards with the Nvidia X server module, and that has much higher performance than the vanilla one that Fedora ships. In the end the reason we offer a choice of types is that there are different needs on the quality vs speed axis. Slower under some circumstances (although on the test systems much faster than packages Cairo and cairoDevice).

Re: [Rd] New version of X11, png and jpeg
Revision r44621 supports (in a limited way) cairo 1.0 and hence I believe
vanilla FC5 -- I found what purports to be a vanilla FC5 box and it works
quite well there.
Two people have reported that the svg(), cairo-pdf() and cairo-ps()
devices produce blank (but not empty) files. I was able to confirm that
on Debian etch (cairo 1.2.4). They do work on cairo 1.4.14 (F8) and
better on a 1.5.10 snapshot.
We've got a working version on Mac OS X, but you need to install cairo.
Finally, the quality of the fonts you see will depend on what fonts you
have installed: if you only have X11 bitmapped fonts, that is what you
will get (and I am getting on our minimally configured Debian etch
machine). Our Fedora installations are mainly using the URW Type 1 fonts
in the urw-fonts RPM. One of the alternatives is RH's liberation fonts
(https://www.redhat.com/promo/fonts/).

Offering an API is something I have considered for the TODO for 2.8.0.
However, we are at the stage of finding out how widely this can be got to
work and how well it works.
This is reasonable.
Simon and I are working on MacOS X, and should have this working via a

Great.
I don't think cairo on
Windows works well enough: e.g. your Cairo() device has more than half the
glyphs missing in the symbol font.
There are certainly issues. Hopefully most of those will be ironed out as
more win32 programs rely on Cairo (e.g. Firefox 3.0).

They do work on cairo 1.4.14 (F8) and better on a 1.5.10 snapshot. My intuition is that there is a missing call to cairo_show_page(). I believe this became unnecessary in the 1.4.x series. This should probably be called any time there is new page (after the first) and when the device is closed. Yes, you are quite right (and of course the 1.5.x docs I was reading didn't say it was needed).

Re: [Rd] New version of X11, png and jpeg
That call is from Cairo 1.2, so looks like our test FC5 box had a later
version of the cairo libraries than the one pkg-config reported.
You should be able to build with --without-cairo until such a time as we
can add a suitable configure test.
Thank you for the report.

Re: [Rd] New version of X11, png and jpeg
Michael,
Would it be at all feasible to make the cairo backend available on
all platforms and have it provide a public API through which an
arbitrary cairo context could be passed as the drawing target?
Offering an API is something I have considered for the TODO for 2.8.0.
However, we are at the stage of finding out how widely this can be got to
work and how well it works.
Simon and I are working on MacOS X, and should have this working via a
static cairo build (without pango) shortly. I don't think cairo on
Windows works well enough: e.g. your Cairo() device has more than half the
glyphs missing in the symbol font.
