SweepGradient
open class SweepGradient : Shader
Summary
| Public constructors |
|
A Shader that draws a sweep gradient around a center point.

|
A Shader that draws a sweep gradient around a center point.

| Inherited functions |
From class Shader
Boolean |
getLocalMatrix(localM: Matrix)
Return true if the shader has a non-identity local matrix.
|
Unit |
setLocalMatrix(localM: Matrix?)
Set the shader's local matrix. Passing null will reset the shader's matrix to identity. If the matrix has scale value as 0, the drawing result is undefined.

Public constructors
<init>
SweepGradient(cx: Float, cy: Float, colors: IntArray, positions: FloatArray?)
A Shader that draws a sweep gradient around a center point.
| Parameters |
cx |
Float: The x-coordinate of the center |
cy |
Float: The y-coordinate of the center |
colors |
Float: The colors to be distributed between around the center. There must be at least 2 colors in the array. This value must never be null. |
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. This value may be null. |
<init>
SweepGradient(cx: Float, cy: Float, color0: Int, color1: Int)
A Shader that draws a sweep gradient around a center point.
| Parameters |
cx |
Float: The x-coordinate of the center |
cy |
Float: The y-coordinate of the center |
color0 |
Float: The color to use at the start of the sweep |
color1 |
Float: The color to use at the end of the sweep |
