Arachne is a program that allows you to resize images without distorting the shape of the things in the image. It does this by either removing or duplicating the boring bits of the image that you don't notice so much. The interesting parts of the image can then retain their original size and shape.
The technique Arachne uses to achieve this is called seam carving, and was developed by Shai Avidan and Ariel Shamir[AvSh2007].
No new features but a few problems were fixed. The configure script for Arachne no longer looks for gdk-pixbuf 0.22 (which it never actually depended on). The Autotools build system was updated and some minor documentation fixes were made. A bug that caused the GTK+ version to sometimes crash on exit has been fixed and some calls to deprecated functions were removed. Some minor documentation problems were fixed.
Arachne can now operate on much larger images. It can open images measuring up to 4096x4096 pixels and if an image is too big for the screen it will scale the displayed version to fit. Some minor bugs relating to dynamic energy were fixed in the Seamstress library.
There have been a few changes from version 1.0.0. Arachne can now read and write JPEG files and can now can stretch images wider and taller than the original. There is also a Windows version (as well as the original GTK+ version). Thanks to a fixed bug in the Seamstress library the dynamic energy option works properly with an image with protection and exposure marks. There have been a few other minor changes and repairs, but the program otherwise remains unchanged.
