构造器详细资料

ShadowFilter

public ShadowFilter()

Construct a ShadowFilter.

ShadowFilter

public ShadowFilter(float radius,
                    float xOffset,
                    float yOffset,
                    float opacity)

Construct a ShadowFilter.

参数:

radius - the radius of the shadow

xOffset - the X offset of the shadow

yOffset - the Y offset of the shadow

opacity - the opacity of the shadow

方法详细资料

setAngle

public void setAngle(float angle)

Specifies the angle of the shadow.

参数:

angle - the angle of the shadow.

参数:

addMargins - true to add margins.

另请参阅:

getAddMargins()

getAddMargins

public boolean getAddMargins()

Get whether to increase the size of the output image to accomodate the shadow.

返回:

true to add margins.
