5.4. 变换路径

每个变换工具（旋转、缩放、透视等）都可以设置为作用于图层、选区或路径。在工具箱中选择变换工具，然后在工具的工具选项对话框中，为“变换：”选项选择图层、选区或路径。这为您提供了一组强大的方法来改变路径的形状而不影响图像的其他元素。

By default a Transform tool, when it is set to affect paths, acts on only one path: the active path for the image, which is shown highlighted in the Paths dialog. You can make a transformation affect more than one path, and possibly other things as well, using the “transform lock” buttons in the Paths dialog. Not only paths, but also layers and channels, can be transform-locked. If you transform one element that is transform-locked, all others will be transformed in the same way. So, for example, if you want to scale a layer and a path by the same amount, click the transform-lock buttons so that “chain” symbols appear next to the layer in the Layers dialog, and the path in the Paths dialog; then use the Scale tool on either the layer or the path, and the other will automatically follow.
