Transforming Paths
Each of the Transform tools (Rotate, Scale, Perspective, etc) can be set to act specifically on paths, using the ‘Affect:’ option in
the tool’s Tool Options dialog. This gives you a powerful set of methods for altering the shapes of paths without affecting other
elements of the image.
the tool’s Tool Options dialog. This gives you a powerful set of methods for altering the shapes of paths without affecting other
elements of the image.
By default a Transform tool, when it is set to affect paths, only acts on a single 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.

Stroking a Path
Figure 7.10: The four paths from the top illustration, each stroked in a different way.
Paths do not alter the appearance of the image pixel data unless they are stroked, using Edit → Stroke Path from the image menu
or the Paths dialog right-click menu, or the ‘Stroke Path’ button in the Tool Options dialog for the Path tool.
or the Paths dialog right-click menu, or the ‘Stroke Path’ button in the Tool Options dialog for the Path tool.
Choosing ‘Stroke Path’ by any of these means brings up a dialog that allows you to control the way the stroking is done. You can
choose from a wide variety of line styles, or you can stroke with any of the Paint tools, including unusual ones such as the Clone
tool, Smudge tool, Eraser, etc.
