使用HERE Map Image API中的“区域资源”时,我试图更改多边形填充的不透明度。

有人能做到这一点吗?

资源documentation在任何地方都没有提到不透明性。可以更改填充的唯一选项是{ "dog" : { "boundingVertices" : { "topLeft": { "x": 0, "y": 1331 }, "topRight": { "x": 2560, "y": 1331 }, "bottomRight": { "x": 2560, "y": 1371 }, "bottomLeft": { "x": 0, "y": 1371 }, "boundingVertices" : { "topLeft": { "x": 33, "y": 31 }, "topRight": { "x": 17, "y": 98 }, "bottomRight": { "x": 102, "y": 56 }, "bottomLeft": { "x": 10, "y": 42 } }, "cat" : { "boundingVertices" : { "topLeft": { "x": 9, "y": 23 }, "topRight": { "x": 37, "y": 53 }, "bottomRight": { "x": 97, "y": 32 }, "bottomLeft": { "x": 85, "y": 58 }, "boundingVertices" : { "topLeft": { "x": 32, "y": 87 }, "topRight": { "x": 23, "y": 86 }, "bottomRight": { "x": 38, "y": 72 }, "bottomLeft": { "x": 90, "y": 45 } } } ,它指定填充颜色本身。

fc颜色参数可以设置为透明。十六进制值的前2位数字表示透明度,其余6位数字为rgb颜色:

fc1=80FF0000
