Morena is a useful Image Acquisition Framework for Java Platform - a bridge between the image acquisition hardware (scanners, cameras) and Java world.

To communicate with the hardware, it uses standard interfaces - Twain for MS Windows and Mac OS X and Sane for number of Unix platforms (AIX, BeOS, Darwin, FreeBSD, HP-UX, Linux, NetBSD, OpenBSD, OS2, Solaris, Unixware). It offers to developer an intuitive, unique and efficient API.

To incorporate scanning capability into your application, you can use very simple API instead of studying hundreds pages of specifications. In the simplest case you need to call just one method to acquire an image, but you can also set contrast, brightness, image frame or many other parameters if necessary.

Client side API: implementation of java.awt.image.ImageProducer.
Device side API:
TWAIN (JNI),
SANE (pure java via saned network protocol) - since version 6.2.
SANE (JNI) - not available yet,
WIA (JNI) - not available yet,
ISIS (JNI) - not available yet,
TWAIN support:
access to current value, default value and array of supported values for all capabilities of boolean, int, double and string type defined in TWAIN 1.9 specification,
support for native and file transfer mode,
support for automatic document feeder (ADF) and duplex scanners.
SANE support: access to current value and meta-info for all SANE driver options, predefined access methods for well-known options.
