Hi Folks,
first, this is probably a fairly dumb question. I'm still trying to
get to grips with QC fundamentals.
Basically, I'm playing round with displaying multiple images in the
QC Viewer. I'm curious, how does it handle image sizes and
resolutions?
I have video input which I believe from the built-in iSight camera
is 640 x 480. The Viewer puts this as a default in the centre. It's
about half the size of the Viewer window, and resizes automatically
(see attached).
Any idea how this works? Or even if it's something I need to bother
with? I have a look at Apple's documentation but it doesn't have
much info. I see parameters like "Pixel Aligned" for the billboard
renderer but there doesn't seem to be much info on what they do.
Many thanks,
Max
