Pixel size for shadow rendering. Smaller values = smoother but heavier. Default is 1.0. Use 0.5 for smoother edges.
final
runtimeType Type
A representation of the runtime type of the object.
no setterinherited
shadowRatio double
Shadow radius ratio for image mode (0.0 ~ 1.0). Use this to match shadow to actual moon area in image. 1.0 means shadow radius = size/2, 0.8 means shadow radius = size/2 * 0.8. Defaults to 1.0.
