Version 1.0 Updated October 1 2005
Page Updated May 13 2006
MediaUtil is an offshoot of the
MediaChest Project to provide a
well packaged Java API for Media Related Utilities.
Below is the Current API Offering from MediaUtil.
LLJTran is an API for performing Lossless Transformations on JPEG image files
which also provides the Capability of handling Exif information.
Following are the key features:
- Supports lossless rotation, transpose, transverse and crop
- Trimming or relocating Non Transformable edge blocks similiar to
jpegtran or processing them
like regular MCU blocks.
- Reading and Modifying Image Header Information (Exif) including Thumbnail
- Built-in transformation of Thumbnail and Orientation marker
- Supports the IterativeReader and IterativeWriter interfaces in
MediaUtil's mediautil.gen.directio package enabling things like Sharing
the jpeg input file with say jkd's ImageReader while reading
- Does not Support Multi-Threading for the same Object to be
used simultaneously by more than one thread. However different threads
can have their own LLJTran Objects.
- Requires JDK 1.5
Download mediautil-1.0.zip and extract it to a suitable folder. Then
include the mediautil-1.0.jar file in your CLASSPATH. The download also includes
source under the src directory and documentation including javadocs under the
