previous canvas state, you can click the [Undo] button in the menu bar (or the [Undo] item in the right-click menu or use the
shortcut key Ctrl + Z). At this time, the canvas will update to the state before the current operation. You can perform this operation
continuously until the canvas returns to the state you desire.
2）If you undo a canvas action and then want to restore to the next canvas state, you can click the [Redo] button in the menu bar
