RadialGradient (float centerX,
float centerY,
float radius,
int[] colors,
float[] stops,
Shader.TileMode tileMode)
创建一个着色器，以给定中心和半径绘制径向渐变。
| Parameters | |
|---|---|
centerX |
float: The x-coordinate of the center of the radius |
centerY |
float: The y-coordinate of the center of the radius |
radius |
float: Must be positive. The radius of the circle for this gradient. |
colors |
int: The colors to be distributed between the center and edge of the circle |
stops |
float: May be null. Valid values are between 0.0f and 1.0f. The relative position of each corresponding color in the colors array. If null, colors are distributed evenly between the center and edge of the circle. |
tileMode |
Shader.TileMode: The Shader tiling mode |
