Align Relative to Document Boundary

By default drawing objects will be aligned in relation to a reference object. The reference object is the one that was last selected.

Use the Draw > Align or Distribute > Relative to Document Boundary command to have all of the selected drawing objects arranged along the border of an image. You will find the Draw menu on the Drawing toolbar.

This command is effective for all of the commands in the Draw > Align or Distribute menu.
