Looks like my english ist too bad (I'm German), because I'm working with Giide's "Ascension's Atlas Tutorial in GIMP" and have some problems there.
On Site 2 stands:
I don't understand what "... and check the box for Initialize from Selection." means. Which box must I checked in Gimp 2.6? I can't find any checkbox with the Name "Initialize from Selection" or anything like that (or a german counterpart).k. Switch to the Channels dialog (if you don't see it, you can make it appear by using the Windows Dockable Dialogs menu option. At the bottom of the channels dialog, click the new channel icon. Name
the new channel Coastline, and check the box for Initialize from Selection.
Please don't let me walk in the dark.
