The LiquidRescale (lqr) library provides a C/C++ API for performing
non-uniform resizing of images by the seam-carving technique.
The library takes images in plain array format as input and converts
them to a multi-size representation.
Following is a list of features:
* Areas in the image can be marked for preservation or discard
* Once the image has been fully processed, the scaling can be done
in real-time. In fact, the information can be saved and read out
later without any further processing
* The resizing is done with a single function which automatically
performs all the necessary operations; it can also work in
successive steps without wasting computational time
* Possibility to tune the carving operation by letting the seams be
less connected, or more rigid, or both
* Can export and import the visibility map (the seams)
* Other images can be attached and undergo the same carving process
as the parent image
* The automatic feature detection algorithm can be tuned by
selecting among different energy gradient functions
* Reports progress through a customizable interface
* A signalling system permits one to cleanly handle errors
The library implements the algorithm described in the paper "Seam
Carving for Content-Aware Image Resizing" by Shai Avidan and Ariel
Shamir, which can be found at
This package contains the shared library.

liblqr (0.3.1-1) unstable; urgency=low
* New Upstream Version
This is a bugfix release. It fixes a serious bug with 16bit images
(therefore, it is actually irrelevant to GIMP users, not so for other
programs such as ImageMagick and DigiKam).
* debian/rules: Be pendantic about symbol changes.
* debian/control:
- Bump Standards-Version.
- Move liblqr-1-0-dbg into the debug section.

liblqr (0.3.0-1) unstable; urgency=low
[ Sandro Tosi ]
* debian/control
- updated my email address
- bump Standards-Version to 3.8.0 (no changes needed)
* debian/watch
- updated to match new upstream tarball name
[ Bernd Zeimetz ]
* New upstream version.
* debian/liblqr-1-0.symbols:
- Updating symbols file to match the symbols in the updated library.
* debian/copyright:
- Linking to GPL-3 and adding 'Copyright' for the Debian packaging
to make lintian happy.
* debian/control:
- Removing duplicate section entry.
2008-10-17 - Bernd Zeimetz <>
liblqr (0.2.0-1) unstable; urgency=low
* New Upstream Version
* debian/watch:
- Updating watch file to fit the new filename.
* debian/liblqr-1-0.symbols:
- In the last version of the library several symbols were not marked as
private by upstream, they are missing now. As the library is new and
only used by one Gimp plugin now and the abi did not change for the
plugin, there was no soname bump.
* debian/rules:
- Install manpages on build.
* debian/liblqr-1-0-dev.manpages:
- Adding file, instaaling devel manpages into the -dev package.
