RI, unfortunately, is not yet 100%. My app is fully ready to go; got it done back in the days of Tiger developer seeds. However, my app uses its own UI (no Aqua). Thus, I had full control over graphics (100% vector-based PDF) as well as drawing primitives. Having said that, Quartz Debug is definitely a very useful tool to flush out RI issues. There is no user-level setting currently in the OS; you need Quartz Debug from devtools. My app works at all scaling factors (to include the non-integral ones such as 1.333), but I found that the Aqua UI was not up to the same degree of compliance. Integral scale factors turned out somewhat OK (e.g. 2.0), but you could tell where bitmapped art was still being used. Non-integral scaling factors were awful for Aqua. I was hoping that Leopard would be the debut and then later Snow Leopard, but alas not yet. > Is there something similar for iPhone development? No. For iPhone OS, you really should use art in the most optimum format. This is currently PNG (i.e. bitmapped). Scaling things on-the-fly ends up eating cycles which means more power consumption. Granted, not nearly as much power as cellular/network communication, but still a waste. > Or is the Xcode mailing list a better place for this question? No, most RI threads have been on this list. Definitely search the archives for other notes or tips/tricks. ___________________________________________________________ Ricky A.
