Acquisition
QPix provides extended acquisition capabilities, supporting all modern image acquisition standards:
- TWAIN: a specification commonly used for interfacing applications with scanners and other imaging devices. Available on all platforms.
- Mac OS X Image Capture: standard method for interfacing applications with scanners and digital cameras on MacOS X. Regarding digital cameras, Image Capture is an implementation of the Picture Transfer Protocol (PTP), a standard defined by the Photographic and Imaging Manufacturers Association (PIMA).
- Windows Image Acquisition: standard method for interfacing applications with digital cameras on Windows. WIA too is an implementation of the Picture Transfer Protocol.
- QuickTime Video: standard method for interfacing applications with video cameras on Mac OS X.
- DirectShow Video: standard method for interfacing applications with video cameras on Windows.
Protocols
QPix organizes all acquisition standards into the following acquisition protocols:
- TWAIN Protocol: covers TWAIN devices on all supported platforms.
- Picture Transfer Protocol: covers photo cameras supported by MacOS X Image Capture and Windows Image Acquisition.
- Video Protocol: covers QuickTime and DirectShow video.
- Mac OS Image Capture Scanner Protocol: covers scanners supported by Image Capture on MacOS X.
Features
QPix provides the following acquisition features:
- Multiple-image acquisition: acquire all pages loaded on a scanner's automatic document feeder (ADF), download all pictures from a digital camera, or acquire a series of frames from a video camera.
- Faceless acquisition: one-click acquisition without showing the device's user interface.
- Direct-to-disk acquisition: acquisition is done directly to disk, thus minimizing memory requirements.
