GradientFactory
public GradientFactory()
gradientInArea
public static Paint gradientInArea(int x0,
int y0,
int width,
int height,
Style style)
- Generate a gradient in the given pixel area following the given style.
This produces a gradient only if the style fill-mode is compatible.
- Parameters:
x0
- The left corner of the area.y0
- The bottom corner of the area.width
- The area width.height
- The area height.style
- The style.
- Returns:
- A gradient paint or null if the style does not specify a
gradient.
linearGradientFromStyle
public static Paint linearGradientFromStyle(float x0,
float y0,
float x1,
float y1,
Style style)
- Generate a linear gradient between two given points corresponding to the
given style.
- Parameters:
x0
- The start point abscissa.y0
- The start point ordinate.x1
- The end point abscissa.y1
- The end point ordinate.style
- The style.
- Returns:
- A paint for the gradient or null if the style specifies no
gradient (the fill mode is not a linear gradient or there is only
one fill colour).
radialGradientFromStyle
public static Paint radialGradientFromStyle(float cx,
float cy,
float radius,
Style style)
radialGradientFromStyle
public static Paint radialGradientFromStyle(float cx,
float cy,
float radius,
float fx,
float fy,
Style style)
- Generate a radial gradient between whose center is at (cx,cy) with the
given radius. The focus (fx,fy) is the start position of the gradient in
the circle.
- Parameters:
cx
- The center point abscissa.cy
- The center point ordinate.fx
- The start point abscissa.fy
- The start point ordinate.radius
- The gradient radius.style
- The style.
- Returns:
- A paint for the gradient or null if the style specifies no
gradient (the fill mode is not a radial gradient or there is only
one fill colour).
