My question(s): Is there a better way to do any of the following?
1) If you want to tell an IKScannerDeviceView what values to use when it first
appears, you might find the keys revealed by the following command helpful:
defaults read com.apple.Image_Capture | grep IK_
These are undocumented, so YMMV. I logged rdar://13878930 to ask that they be
documented, or that a supported method be created.
2) If you want to know when a scan is starting or finished, you'll can
listening for these two notifications coming from the ICScannerDevice:
IKScannerDeviceViewScanStarted, IKScannerDeviceViewScanDone.
3) If you want to know what resolution (aka DPI) was used for a scan that was
just delivered to your delegate's
"-scannerDeviceView:didScanToURL:fileData:error:', you can examine [[deviceView
selectedDevice] selectedFunctionalUnit].
