Libraries

libgwyprocess: A new function to remove grains touching image borders. libgwyprocess: New grain quantities: Radius and position of maximum inscribed disc and minimum excscribed circle, area of grain convex hull, mean radius. libgwyapp: Critical warning/crash if the last visible channel of a file is deleted and this channel has a mask. libgwyapp: Setting a channel or graph visibility key in a container actually shows or hides the corresponding data.

Modules

Neural network: Split to two functions: training and application. Networks can be saved, trained on multiple data (sequentially), training signal can be masked, units of the output can be specified. APE file: Channel labelling for various modes was corrected. Createc: Dimensions and values of imported data was corrected, all channels are imported now. IGOR file: Crash on files that contain no channel titles was fixed. Selection manager tool: Chosen selection is shown in the data window. Remove Grain by Threshold: Can also remove grains touching image borders. Grain Statistics: Select Inscribed Discs and Select Excscribed Circles create circular selections visualising the corresponding discs/circles. Grain correlations: Really works when run non-interactively.

Other

Compatibility with newer version of GLib that deprecate various things was improved.
