Locking a Stack
|
|
When a stack is first added to the workspace it is made
unlocked. In other words it is free to be translated, cropped, etc... It is
useful to be able to lock the stack to prevent against accidental editing.
To do this click on the lock symbol next to the stack name.
Clicking again will toggle the lock state of the stack. Note that the lock
prevents editing whether the stack is selected or not.
You may also select Lock All or Unlock All from the View menu item to lock or unlock all the stacks. |
