stops

public float[] stops

Indicates the positions corresponding the shading colors in the Shader#shaderColors array.

Color stops values monotonically increase from 0 to 1.0. If the stops parameter is null, the colors will be evenly shaded.

RadialShader

public RadialShader()

Default constructor used to create a RadialShader.

Calling this constructor will automatically invoke RadialShader#RadialShader(Point, float, float[], Color[], TileMode) to create a radial shader.

RadialShader

public RadialShader(Point newPoint,
                    float newRadius,
                    float[] newStops,
                    Color[] newColors,
                    Shader.TileMode newTileMode)

A constructor used to create a RadialShader based on the specified center point, radius, colors, and tile mode.

参数:

newPoint - Indicates the coordinate of the center point of the radial shader.

newRadius - Indicates the radius of the radial shader.

newStops - Indicates the positions corresponding to the colors in newColors. This parameter can be null.

newColors - Indicates the array of radial shading colors.

newTileMode - Indicates the tile mode used to shade colors when the drawn object exceeds the shading area defined by the radial shader.
