产品表达导致要素无法呈现 [英] Product expression causes features to not render

问题描述

我有一个具有线性特征的地图，这些特征的样式具有偏移量:

I have a map with linear features that have an offset in the style:

"line-offset": {
  "stops": [ [ 12, 0 ], [ 16, 2 ] ]
},

如果我尝试将2值替换为

If I try to substitute the value 2 with a product expression, the features fail to render.

"line-offset": {
  "stops": [ [ 12, 0 ], [ 16, ["*", 2, 1] ] ]
},

javascript控制台中没有错误.

There is no error in the javascript console.

我正在使用最新版本的v0.49.0.

I am using the latest version, v0.49.0.

我正确使用了表达式吗?

Am I using the expression correctly?

推荐答案

要使用

To use expressions, you would need to change the syntax:

"line-offset": [
  "interpolate",
  [ "linear" ],
  [ "zoom" ],
  12, 0,
  16, ["*", 2, 1],
]
