[PD] pix_data capture speed

[David McCarthy]

hey, does anyone know the minimum time pix_data needs on a pixel coordinate to
sample the colour info?

Ive tried using 'until' to scan across a regular grid of pixels as fast as
possible, say 10000 but it dosnt seem to work for me (no results), but maybe my
code is wrong

Metro works fine but dosnt go below 1 ms (too slow)

havnt tried pulse yet...

Seems to get more positive results the slower I sample...


Thanks for any feedback,
