Little time has passed since our last release and yet there is new major
functionality. Hugin has received a Python scripting interface and new
lens calibration tool. A critical bug affecting a significant number of
Mac users has been fixed and many general improvements have been made.

_Lens Calibration Tool_

Lenses are designed to follow a perfect geometric model. For rectilinear
lenses, a straight line in the depicted scene should be straight in the
picture. This is not always the case: most lenses have an inherent
deviation from the perfect model, resulting in imperfections such as
pincushion or barrel distortion in rectilinear lenses.

Adherence to the perfect geometric model is desirable for aesthetic purposes
and indespensible to achieve proper alignment when stitching images.
Hugin can calculate lens distortion parameters on the fly when optimizing
a project, however this requires more control points and more computational
effort than a project starting with a calibrated lens, and is prone to more

The new lens calibration tool calculates the distortion parameters of a
lens based on an input image. The input image must contain straight
lines, ideally many of them at different distances from the center of the
lens, covering at least one quadrant of the image. The calculated
parameters are valid for a given combination of focal distance,
aperture (F-stop), and sensor.

The values, saved into a lens profile, can be used in Hugin to achieve
a better stitch, or on single images taken with this lens / settings
combination to achieve a more aesthetically pleasing outcome.

_Python Scripting Interface_

Hugin now exposes some of its data structure and functionalities through
a Python module. To get started with scripting, start your Python
interpreter and type:

   >>> import hsi
   >>> help (hsi)

Standalone Python programs can access a panorama object with Hugin's
functionality. It is possible to develop complete command line and
even GUI tools based on this module.

The Python Scripting Interface does not work on Mac OSX yet.

_Python Plugin Interface_

Hugin can now run Python scripts inside the application. In an enabled
Hugin binary, a new "Actions" menu gives access to system-wide plugins
distributed with Hugin. Moreover, plugins can be written, modified,
customized in the user's own directory.

Currently there are only a few plugins available, but we expect the
body of available plugins and functionality to grow organically as
the interface is being made available to the general public.

The Python Plugin Interface does not work on Mac OSX yet.

_Other Improvements_

* PTBatcherGUI has matured to become the default processor for
  stitching projects.
* ICC profiles saved in output.
* Support for newer Olympus camera.
* Improved auto cropping.
* New mask type: exclude region from all images shot with the same lens
* Copy&paste of masks in Mask Tab
* Show extent of active masks and crop in Mask Editor
* Fix for critical issue affecting stitching on Mac OS X Leopard.
* Many more improvements and bug fixes.

_Libraries and Build_

The Python interface introduces new dependencies:
* SWIG >2.0
* Python


Upgrading from previous versions of Hugin should be seamless. If you do have
problems with old settings, these can be reset in the Preferences by clicking
'Load defaults'.

It is strongly recommeded to set the default control point detector to
Hugin's CPFind. It is the only control point generator endorsed by Hugin.
Third-party generators may be compatible with the plug-in architecture.


Users compiling from source refer to the dependencies listed at

and the build processes listed at

More information in the README and INSTALL_cmake files in the tarball.


Fast Preview is affected by a threading issue.

There is a known problem building Hugin with CMake 2.8.5rc2.
Workaround: Upgrade to a newer CMake version.

Mac OS X 10.7 Lion has been recently introduced by Apple.
Initial reports indicate that it is not compatible with Hugin.
Support will start as soon as possible.

An updated list of issues deemed to be critical, including discussions
and workarounds is in the issue tracker.


Hugin is looking for a new release manager.

The process is documented in detail at

I will keep hanging out on Hugin-PTX and will gladly help the next
release manager transition into the role.


Thanks to all the contributors to this release and members of the hugin-ptx
mailing list, too many to mention here.
