Is there a cocoa framework for image scanning?

On Snow Leopard and later, Image Kit includes classes for scanning and importing from cameras. There's also a lower-level framework, ImageCaptureCore. Both frameworks are documented in the Image Capture Applications Programming Guide in Apple's Documentation Archive.

On Leopard, you'll have to use Image Capture, the less-documented, less-modern, less-reliable API. (This stands in contrast to the Image Capture application, which has always been great.) I hope you can require Snow Leopard.

I know this post is old but it is still very hard to find any good information about this topic on the web. Long story short .. I made a bundle (including multiple selection support) for it. Check it out (open source) on Github: https://github.com/ckteebe/SPScannerCaptureWindow
