Converting Path to Selection

Once your path is complete, you can convert this path into a selection. This is done by using the “Select->From Path” command, which creates a selection from the active path, typically the last path you’ve created or edited.

If your path is not closed, GIMP will automatically connect the endpoints with a straight line, leaving the original path unchanged. To access this command, you can either use the keyboard shortcut Shift + V or click on the “Path to Selection” button in the Path dialog.
