The LinearGradientPaint class provides a way to fill a {@link java.awt.Shape} with a linear color gradient pattern. The user mayspecify 2 or more gradient colors, and this paint will provide an interpolation between each color. The user also specifies start and end points which define where in user space the color gradient should begin and end.
The user must provide an array of floats specifying how to distribute the colors along the gradient. These values should range from 0.0 to 1.0 and act like keyframes along the gradient (they mark where the gradient should be exactly a particular color).
For example:

Point2D start = new Point2D.Float(0, 0); Point2D end = new Point2D.Float(100,100); float[] dist = {0.0, 0.2, 1.0}; Color[] colors = {Color.red, Color.white, Color.blue}; LinearGradientPaint p = new LinearGradientPaint(start, end, dist, colors);
This code will create a LinearGradientPaint which interpolates between red and white for the first 20% of the gradient and between white and blue for the remaining 80%.
In the event that the user does not set the first keyframe value equal to 0 and the last keyframe value equal to 1, keyframes will be created at these positions and the first and last colors will be replicated there. So, if a user specifies the following arrays to construct a gradient:
{Color.blue, Color.red}, {.3, .7}
this will be converted to a gradient with the following keyframes: {Color.blue, Color.blue, Color.red, Color.red}, {0, .3, .7, 1}
The user may also select what action the LinearGradientPaint should take when filling color outside the start and end points. If no cycle method is specified, NO_CYCLE will be chosen by default, so the endpoint colors will be used to fill the remaining area.
The following image demonstrates the options NO_CYCLE and REFLECT.

The colorSpace parameter allows the user to specify in which colorspace the interpolation should be performed, default sRGB or linearized RGB. @author Nicholas Talian, Vincent Hardy, Jim Graham, Jerry Evans @author Vincent Hardy @version $Id: LinearGradientPaint.java,v 1.6 2005/03/27 08:58:32 cam Exp $ @see java.awt.Paint @see java.awt.Graphics2D#setPaint
