属性

名称	类型	默认值	说明
begin	Optional[OffsetValue]	required	The offset at which stop 0.0 of the gradient is placed.
end	Optional[OffsetValue]	required	The offset at which stop 1.0 of the gradient is placed.
colors	list[ColorValue]	required	The colors the gradient should obtain at each of the stops. This list must contain at least two colors. Note: If color_stops is not None, this list must have the same length as color_stops.
color_stops	Optional[list[Number]]	None	A list of values from 0.0 to 1.0 that denote fractions along the gradient. Note: If non-none, this list must have the same length as colors. If the first value is not 0.0, then a stop with position 0.0 and a color equal to the first color in colors is implied. If the last value is not 1.0, then a stop with position 1.0 and a color equal to the last color in colors is implied.
tile_mode	GradientTileMode	GradientTileMode.CLAMP	How this gradient should tile the plane beyond in the region before begin and after end.
