In < XXXX@XXXXX.COM >,
That's a huge help, but AFAICS the SM501 only offers acceleration for
things like colourspace conversion and scaling of decoded frames. NVidia
and ATI cards have motion compensation acceleration, but the APIs are
closed and the RO market is maybe too small to get licences. So I think
RISC OS will have to rely solely on software decoding. Even 600MHz VIA
C3 processors struggle and rely on the MPEG decoders on their Unichrome
graphics chips. Those CPUs are renowned for lousy FP, but it's got to be
better than none at all.
Apparently the Filer can display thumbnails and the module it uses to do
it can render Drawfiles. But it doesn't say whether it can antialias
Drawfiles (or render Artworks with antialiasing), and there's definitely
no sign of Drawfiles replacing Iconsprites.
That's one size for three different pixel formats, not three sizes.
No, you're missing the point. Windows' ability to display icons at
different sizes and offer a resizable task/icon bar has been slightly
more flexible than RISC OS for years. MacOS X and common Linux desktops
are further ahead still to a similar extent that RISC OS' font rendering
is ahead of DOS. ISTR hearing that Vista will support vector icons too.
