Package Gtk.Gamma_Curve

The Gtk_Gamma_Curve widget is a child of Gtk_Curve specifically for editing gamma curves, which are used in graphics applications such as the Gimp.

The Gamma_Curve widget shows a curve which the user can edit with the mouse just like a Gtk_Curve widget. On the right of the curve it also displays 5 buttons, 3 of which change between the 3 curve modes (spline, linear and free), and the other 2 set the curve to a particular gamma value, or reset it to a straight line.
