Hi, Dave Neary <dneary@xxxxxxx> writes: > My understanding came from looking at libgimpthumb Well, I was talking about libgimp explicitely since I think that's what the question was all about. Of course libgimpbase, libgimpcolor, libgimpmath, libgimpthumb and libgimpwidgets play a completely different role here. These libraries contain code that is shared between the core and plug-ins. Still most of this code has been developed in the libraries and was never before part of the GIMP core. libgimpthumb is an exception here but it has been written from scratch with the intention to move it into a library eventually. Same is true for the GimpUnitComboBox that I recently added to the core but already noted that it's supposed to end up in libgimpwidgets as soon as it's full-featured and the API has settled. Sven
