- - Fix another issue in the rectilinear projection code
+* Fix another issue in the rectilinear projection code
that affected non-horizontally shot pictures.
- - Use a more robust forumla for spherical distance computation.

code. This improves accuracy quite a bit, mostly in
wideangle images.

- - Add visibility command line option.
- - Reset known hills when loading new image.
- - Cancel "Choose Hill" dialog on Esc.
- - Make code -Wall clean.

+* Change scale factor to "focal length in 35mm" this makes it
independent of the image size. One can now scale an already
oriented image without invalidating the orientation information.
- - gipfel now tries to find a reasonable default for the scale value
+* gipfel now tries to find a reasonable default for the scale value
when opening new images based on the "Focal Length In 35mm" Exif
tag, if it exists.
- - GPS Exif tags are used if they exist.
- - gipfel can now correct lens distortion (see README).
- - Switched to use maxima for symbolic computation and code generation.
- - Switched to use th GNU Scientific Library instead of ccmath.
- - Major simplifications of the projection code.
- - Removed the "guess" button.
- - Added bilinear interpolation for image stitching (-b option).
- - Added range option (-r) for image stitching.
- - Known mountains must now be marked with the middle mouse button

Panorama mode now works with the great view from Mount Everest by
Roddy Mackenzie (google for mackenzie everest panorama).

- - Display of GPS-tracks.
+* Display of GPS-tracks.
GPS-tracks e.g. those that can be downloaded from www.alpin-koordinaten.de
("Fugawi 3 TXT" format) or self-recored ones, can be projected
on your digital images!
- - Load/save perspective data from/to JPEG comment section.
+* Load/save perspective data from/to JPEG comment section.
This means, that you can create and share "gipfel-enabled" images.
Whenever you want, you can use these images and e.g. display your
GPS-tracks on them, without further fiddling to find the view parameters.
- - Experimental support for panorama images.
+* Experimental support for panorama images.
gipfel can now handle images with panoramic projection. Check the
"Options" menu entry.

+* Data file from www.alpin-koordinaten.de
With the kind permission of the guys from www.alpin-koordinaten.de, the
gipfel tarball now contains a default datafile with more than 6000 entries
from around the world.
- - Duplicate GPS entry elimation.
- - Show parameter values in control window.
+* Duplicate GPS entry elimation.
+* Show parameter values in control window.
No need to choose your viewpoint on the commandline. Use the new
"peak-choosing" widget to find your viewpoint interactively.
