This is very interesting. It isn’t obvious to me why Cairo should be better for environments where FPU can be a bottleneck (e.g. neo1973 or multicore.) Does Cairo use integer math in all of its scaling operations?

/me goes to look at gdk and Cairo source.

Banding -> Floyd-Steinberg dithering and whatever newer variants apply (showing my age here).

The banding can be greatly reduced by applying a film grain or similar (scatter HSV with hue set to zero) it breaks up the bands of colour but keeps the gradient.

Rather than rewrite the world due to lack of floating point to scale pixmaps, why don’t you pre-scale the pixmaps at build time so that they can just be rendered as bitmaps? And then, if necessary, fix the code that renders them so that if the scale is 1:1 it doesn’t do any fancy floating point math? This seems more productive than reimplementation.

You could see this ‘iPhone Human Interface Guidelines’ if you want, is very interesting…
http://developer.apple.com/documentation/iPhone/Conceptual/iPhoneHIG/

I think it wold be good if someone in the OpenMoko team get inspired by that interface guideline. of course, i’am not telling that open moko should be exactly like the iPhone.

Good luck.

Nice, but the virtual keyboard signs are way too small (they are even smaller than the application font). There are too many wasted pixels in there, you should make the letters bigger.

I know, it’s not the subject.

But, why button on first capture is ugly ? (Profile button).

I have the same problem in Poky Linux, is it a problem from GTK+ ?

Thanks.

Hi Thomas,
Have you looked at AGG (Anti Grain Geometry: http://www.antigrain.com)? It is used in the GTK2 (CVS) version of roadmap (roadmap.digitalomaha.net) and has very good antialiasing, blending, etc… – it is also pretty fast – not sure if it would otherwise meet your needs.
