quickcam 4000 pro how to manipulate zoom from c++ code

Archived from groups: alt.comp.periphs.webcam (More info?)

hi,
does anybody knows if it's possible to manipulate the parameters of a
logitech quickcam 4000 pro directly from c++ code?

for example initialize the camera resolution to 320*240 or the zoom to
200% at the start of the application...

my application crash if the resolution has change by another one from
320*240 to 640*480 and it would be interesting to put two buttons for
the zoom in the main window and not have to open the control panel
everytime.

thanks

Hi,
I can't find in the c++ code nothing about manipulate the zoom...is it
there?

Anyway it seems that your application's zoom doesn't act directly on
the QC4000 control panel but do an "external" zoom on the live
video...isn't it?

thanks,
