1. Resizing a Rectangular or Elliptical Region To resize a rectangular or elliptical region use the following procedure Step Action 1 Place the pointer above the edge or corner of region s outline 2 When the pointer changes to a double headed arrow cursor drag the region outline Regions drawn with a two dimensional Region Tool Rectangular Ellipse Trace or Auto Trace must be at least 2x2 in size to be valid in MetaFluor Note You will be able to resize the region only in the direction indicated by the double arrows To stretch the region horizontally and vertically simultaneously the pointer must be over the corner of the region outline so that the double arrows are pointing diagonally 3 Release the mouse button when the region is the desired size Note While you are resizing a region you can determine its size and location by looking at the status line in the Region Toolbar it will display Region left top width height MetaFluor 549 Version 7 0 MetaFluor User s Guide Resizing or Reshaping a Line Region To resize a line region drawn with any of the line region tools use the following procedure Step Action 1 With the Locator Tool click the line region once to make it the active region Place the pointer over the line Double click the line Round handles will appear at the ends of the line region If the line region consists of more than one segment nodes will appear at ea
