Description Andi Clemens 2010-03-06 12:05:47 UTC 
Version:           unknown (using 4.4.1 (KDE 4.4.1), Arch Linux)
Compiler:          gcc
OS:                Linux (i686) release 2.6.32-ARCH

A free curve is not restored correctly (in the BWSepia filter), instead it seems to be reset (it is just a strait diagonal line). The smooth curve however works as expected.
Comment 1 caulier.gilles 2010-03-06 23:09:29 UTC 
Yes, and it's done using interpolation provided by smooth algorithm. Why ? because if you set a free curves with a 16 bits color depth image, you need to save 65536 values somewhere (currently in digiKam rc file)... It's not clean...

Still valid with 4.0.0-beta1
Comment 4 caulier.gilles 2014-08-29 15:19:29 UTC 
Not reproducible with current implementation from git/master
