Constructor Details

ColorGradient

public ColorGradient(Color... colors)

Constructor.

Parameters:

colors - Colors to set.

Method Details

getColors

public final List<Color> getColors()

Get the color-bands.

Returns:

Colors.

setColors

public void setColors(Color... colors)

Set color-bands. When multiple colors are set, gradient parameters may be set additionally using methods setGradient(int, int, int, int) and setGradient(int, int, int).

Parameters:

colors - Colors to set.

setGradient

public void setGradient(int x1,
 int y1,
 int x2,
 int y2)

Set parameters for linear gradient. All parameter values are percentage values in the bounding box. Color-stops will be at equal intervals based on the number of colors defined using setColors(Color...).

Parameters:

x1 - Must be a value from 0 to 100.

y1 - Must be a value from 0 to 100.

x2 - Must be a value from 0 to 100.

y2 - Must be a value from 0 to 100.

setGradient

public void setGradient(int x,
 int y,
 int r)

Set parameters for radial gradient. All parameter values are percentage values in the bounding box (starts at the center and moves out radially). Color-stops will be at equal intervals based on the number of colors defined using setColors(Color...).

Parameters:

x - Must be a value from 0 to 100.

y - Must be a value from 0 to 100.

r - Must be a value from 0 to 100.

toString

public String toString()

Overrides:
