包路径：org.geotools.styling.Fill
类名称：Fill
方法名：getOpacity

Fill.getOpacity介绍

[英]This specifies the level of translucency to use when rendering the fill.
The value is encoded as a floating-point value between 0.0 and 1.0 with 0.0 representing totally transparent and 1.0 representing totally opaque, with a linear scale of translucency for intermediate values.
For example, "0.65" would represent 65% opacity. The default value is 1.0 (opaque).
[中]这指定渲染填充时要使用的半透明级别。
该值被编码为介于0.0和1.0之间的浮点值，0.0表示完全透明，1.0表示完全不透明，中间值具有半透明的线性比例。
例如，“0.65”表示65%的不透明度。默认值为1.0（不透明）。
