I am using xsane 0.61 with 1.01/1.02/1.03 versions of sane.
I have a web cam (Creative Labs webcam 3 USB) on one usb port and usb
scanner (Agfa 1212u) on the other port.
xscanimage correctly sees both devices and allows me to chose the input
device.
How do I get xsane to use the scanner instead of the webcam?
- A second problem with xsane and the webcam is that yellow areas of the
picture show up as blue. I suspect that xsane is expecting an rgb image, but
most webcams return a bgr or is it gbr? It may be useful to add a v4l
interface config that allows swapping the rgb components.
- A third problem with the xsane v4l interface, is that it appears to be
using the wrong buffer for pulling its data.... ie, the first preview gives
a blank image (black) and the second attempt gives a correct image... this
continues... the preview data is always 1 picture behind the last picture
taken from the camera. I know the ov511 camera driver has 2 image buffers
and toggles between them. This can probably be fixed with a v4l sync call.
Is anyone else seeing similar problems?
