hi,
to the extent i know there is no facility to scale graphics image in inferno
and plan9. long back when i went thru ATI graphics chip specification and
another set-top box ASIC spec, I found that these accelerations are
supported in hardware. here are my questions along these lines:

- do other platforms like Windows, Mac use the hardware facilities like this
to do image scaling (like submit the task to graphics card, then read the
result back)?
- do plan9, inferno graphics modules do this? to the extent i know they
dont.
- how is graphics scaling done in plan9/inferno? are there any software
implementations like library routines written?
- are there any command-line tools to rescale images, etc? i remember
earlier edition of plan9 had command-line tools.

please provide me any pointers.

thanks
dharani
