Well, they already ship such panels. I don't have the slide handy,
but I remember looking at the entire product lineup, and I believe
the highest dpi device is now hovering around 200 dpi.
I know it's been over 100dpi for a little while. I haven't checked
the specs myself though.
I'm not surprised, just a bit disappointed. Other than the NSCursor
issue, framework scaling is working as advertised.
I'd still expect RI to become a mainstream feature in the Leopard time-
frame. There have been noises for a while about high-dpi displays
from the LCD manufacturers. But I suppose we'll have to wait and see
what Apple releases hardware-wise.
(The only query I have really about RI is what happens with
machines that have a normal panel and a high-dpi panel...
presumably someone at Apple has thought this through, or is doing
so right now.)
You mean dual monitors? It should "just work". After all, if your
app draws to points and not pixels, it is now "resolution
independent". One square inch worth of graphics your app draws will
occupy a physical inch on either monitor, no matter what the
individual monitor's dpi is.
Yeah, I'm not sure that's actually how things currently work in
practice. I think, presently, there is a lot of stuff tied to the
idea that one window has one backing buffer with a single scale
factor. So if you drag a window so that it overlaps the boundary
between the two displays, I think things will not be as one would
really like.
Kind regards,
Alastair.
