The Inside and Outside tabs of the Layer Properties tool window select the inside and outside coloring algorithms. They also contain additional coloring settings.
These coloring settings specify how the index value returned by the selected coloring algorithm is interpreted by the gradient.
Specifies how quickly the colors in the gradient follow each other. Values larger than 1 increase the color density. Values below 1 decrease the color density. The color density must be larger than 0.
The index value is multiplied by the color density.
Selects a transfer function that translates the index value, multiplied by the color density value, to an entry in the gradient.
Specifies the solid color, which can be used for special purposes. See Solid color.
Specifies an optional offset in the gradient. This value is added to the index value after applying the Transfer function. Since the gradient contains 400 entries, the offset value can range from 0 to 399.
You can achieve the same effect by rotating the gradient, but the offset can be specified for Inside and Outside coloring algorithms separately.
Specifies if the gradient must be repeated. When checked, the index value will wrap around when it reaches 1. So, index values of 0, 1, 2, and 3 all map to the same gradient index. Otherwise, the index value is limited to 1, so all colors in the gradient are only used once.
