Class SVGGradientElem

      com.tinyline.svg.SVGGradientElem

public class SVGGradientElem

extends SVGNode

The SVGGradientElem class implements the 'linearGradient' or the 'radialGradient' element.

Gradients consist of continuously smooth color transitions along a vector from one color to another. This class provides for two types of gradients, linear gradients and radial gradients.

Field Summary

TinyColor	gcolor The gradient color.
