SweepGradient (float cx,
float cy,
int[] colors,
float[] positions)
Shader的一个子类，它围绕中心点绘制一个渐变梯度。
| Parameters | |
|---|---|
cx |
float: The x-coordinate of the center |
cy |
float: The y-coordinate of the center |
colors |
int: The colors to be distributed between around the center. There must be at least 2 colors in the array. |
positions |
float: May be NULL. The relative position of each corresponding color in the colors array, beginning with 0 and ending with 1.0. If the values are not monotonic, the drawing may produce unexpected results. If positions is NULL, then the colors are automatically spaced evenly. |
