CanvasGradient - Web APIs 编辑

The CanvasGradient interface represents an opaque object describing a gradient. It is returned by the methods CanvasRenderingContext2D.createLinearGradient() or CanvasRenderingContext2D.createRadialGradient().

It can be used as a fillStyle or strokeStyle.

Properties

As an opaque object, there is no exposed property.

Methods

CanvasGradient.addColorStop()

Adds a new stop, defined by an offset and a color, to the gradient. If the offset is not between 0 and 1, inclusive, an INDEX_SIZE_ERR is raised; if the color can't be parsed as a CSS <color>, a SYNTAX_ERR is raised.
