    CanvasGradient

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

    Properties

    Representing an opaque object, there is no exposed property.

    Methods

    There is no inherited method.

    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 an INDEX_SIZE_ERR is raised, if the color can't be parsed as a CSS <color>, a SYNTAX_ERR is raised.

    [1] Before Gecko 5.0, (Firefox 5.0 / Thunderbird 5.0 / SeaMonkey 2.2), specifying non-finite values when adding color stops through a call to addColorStop() incorrectly throws SYNTAX_ERR instead of INDEX_SIZE_ERR.
