Gradient bar shows default gradient and interpolation types
Gra dient bar —Presents an editable representation
of the gradient being created. The effect of the
gradient moves from left (start point) to r ight (end
point).
By default, t hree flags appear along the b ottom
edge of a red/green/blue gradient. E ach flag
controls a color (or map). The currently selec ted
flag is green, and its RGB va lue and its position
in the gradient (in the range 0 to 100) appear
above the gradient bar. Each gradient can have any
number of flags.
The gradient bar has the following features:
• Click anywhere along the bottom edge to c reate
additional flags.
• Drag any flag to adjust the position of its color
(or map) within the gradient. The start and end
flags (Flag #1 at 0 and Flag #2 at 100) cannot b e
moved. However, other flags can occupy these
positions and still be moved.
• More than one flag can occupy a given position.
If two flags are at t he same position, a slight
edge appears between the colors. With three or
more flags at the same position, the edge is a
hard line.
