来自「在Linux开发环境下实现JPEG_LS压缩标注」· 代码 · 共 40 行

Last updated Mon Oct 12 22:56:53 EDT 1998

This is a preliminary implementation of the proposed JPEG-LS standard,
DIS 14495. See "http://www.jpeg.org/public/jpegnew.htm" for the text of
the committee draft of this standard (which has since been updated, but
electronic versions are not allowed to be distributed due to ISO rules).

Limitations.

The fully lossless mode has been more extensively tested than the
near lossless mode, though the latter appears to work.

The compressed datastream is now interchangable with the HP LOCO 0.90
implementation from their web page. See "http://www.hpl.hp.com/loco/".

It only handles one component (ie. grayscale images) for now.

Usage.

See the man page.

Installation

1. Edit the Makefile if necessary, to specify include paths for makedepend

2. make World (cleans, depends, compiles and tests)

If you really hate makedepend, just type "make"

Miscellaneous.

This experiment is actual part of a larger package, the dicom3tools package
for medical images, which is why all sorts of wierd template generate source
files are needed for the compilation.
