Class: GTransform ​

Defined in: packages/core-ol/src/interactions/transform.ts:70

Experimental

要素变换交互（平移 / 旋转 / 缩放 / 拉伸）。

基于 ol-ext 的 Transform 交互封装，提供 geoverse 统一的 start/stop/setMap/destroy 生命周期与事件订阅。与 FeatureEditor （顶点级编辑）互补：整体变换用本类，顶点编辑用 FeatureEditor。

依赖可选 peerDependency ol-ext——仅使用本类时才需 npm i ol-ext（UMD 包已内置）。API 可能在后续版本调整。
