Flip Segment/Selection This option does a right-to-left ﬂip of the selected range (segment or selection), ﬂipping all colors and

endpoint locations.

Replicate Segment/Selection This option splits the selected range (segment or selection) into two parts, each of which is a

perfect compressed copy of the original range.

Split Segments at Midpoints This option splits each segment in the selected range in into two segments, splitting at the location

of the white triangle.

Split Segments Uniformly This option is similar to the previous one, but it splits each segment halfway between the endpoints,

instead of at the white triangle.

Delete Selection This option deletes all segments in the selected range, (segment or selection) replacing them with a single black

triangle at the center, and enlarging the segments on both sides to ﬁll the void.

Re-center Segment’s midpoint/Selection midpoints This option moves the white triangle for each segment in the selected

range to a point halfway between the neighboring black triangles.

Re-distribute Handles in Segment/Selection This option causes the black and white triangles in the selected range to be shifted

so that the distances from one to the next are all equal.

Blend Endpoints’ Colors This option is only available if more than one segment is selected. It causes the colors at interior

endpoints in the range to be averaged, so that the transition from each segment to the next is smooth.

Blend Endpoints’ Opacity This option does the same thing as the previous option, but with opacity instead of color.

Caution

There is no "undo" available within the Gradient Editor, so be careful!

13.3.5 Palettes Dialog

Figure 13.36: The Palettes dialog

A palette is a set of discrete colors, in no particular order. See the Palettes section for basic information on palettes and how they

can be created and used.

The Palettes dialog is used to select a palette, by clicking on it in a list or grid view. A few dozen more or less randomly chosen

palettes are supplied with GIMP, and you can easily add new palettes of your own. The Palettes dialog also give you access to

several operations for creating new palettes or manipulating the ones that already exist.
