Digital Photography in the GNOME environment 14/17 :hy an API for GNOME? v provide a standard GUI for scanning and/or image capture Use SANE and a front-end like XSane. v provide a simple API to acquire a picture from an application Typical use: send a snail-mail via e-mail using a flatbed scanner. You'd only need to add "Scan..." to the mail application. Digital Photography in the GNOME environment 15/17 Conclusion v Still more general work v Still more devices to support v Real GNOME integration Digital Photography in the GNOME environment 16/17 4uestions ?
