gipfel ChangeLog
=================
+gipfel-0.2.0
+ - Change orientation format in jpeg header to make 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
+ when opening new images based on the "Focal Length In 35mm" Exif
+ tag, if it exists.
gipfel-0.1.3
- Add stitching mode (gipfel -s). See README for details.
