Cropping camera image

May 19, 2011 at 3:18 PM


I'm using a logitech quickcam pro c910 (and a 9000) as development devices, but i can't set the resolution of them higher than 800x600. Actually that resolution is sharp enough for me, but it's still the wrong aspect ratio. So i wonder if it's possible to crop the captured video image before i display it to the scene. If i have my application in a different resolution than my camera image, the scenegraph just scales the image to fill the screen. 

I'm not afraid to alter the source code for goblin, but considering future upgrades i'd rather not change anything just yet.

Are you doing any tracking with the video image with wrong aspect ration? If so, does it track?
