Constructors Summary

public RadialGradientPaintDef(float cx, float cy, float fx, float fy, float r, float[] fractions, int[] rgba, int cycleMethod, boolean isObjectBBox, Transform gradientTransform) Constructs an RadialGradientPaint. param cx the gradient x-axis origin param cy the gradient y-axis orign param fx the gradient x-axis focal point param fy the gradient y-axis focal point param r the gradient radius param fractions the array of stop values param rgba the array of ARGB color values param cycleMethod one of the cycle methods (CYCLE_NONE, CYCLE_REPEAT, CYCLE_REFLECT param isObjectBBox if set to true, the RenderGraphic's current paintTarget object bounding box should be used to append and additional transform to the gradientTransform. The objectBoundingBox transform is appended to the right of the gradientTransform. param gradientTransform an additional transform to add between the device coordinate space and the gradient's coordinate space. this.cx = cx; this.cy = cy; this.fx = fx; this.fy = fy; this.r = r; this.fractions = fractions; this.rgba = rgba; this.cycleMethod = cycleMethod; this.isObjectBBox = isObjectBBox; this.gradientTransform = gradientTransform;
