Public constructors
SweepGradient
public SweepGradient (float cx,
float cy,
int color0,
int color1)
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 |
int : The sRGB color to use at the start of the sweep |
color1 |
int : The sRGB color to use at the end of the sweep |
SweepGradient
public SweepGradient (float cx,
float cy,
int[] colors,
float[] positions)
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 |
int : The sRGB colors to be distributed between around the center.
There must be at least 2 colors in the array.
This value cannot 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 . |
SweepGradient
public SweepGradient (float cx,
float cy,
long color0,
long color1)
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 |
long : The color to use at the start of the sweep |
color1 |
long : The color to use at the end of the sweep |
SweepGradient
public SweepGradient (float cx,
float cy,
long[] colors,
float[] positions)
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 |
long : The colors to be distributed between around the center.
There must be at least 2 colors in the array.
This value cannot 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 . |
Throws |
IllegalArgumentException |
if there are less than two colors, the colors do
not share the same ColorSpace or do not use a valid one, or positions
is not null and has a different length from colors . |
