VTS Graphic Editor: Scaling

Applies to:  Arc, Bitmap, Border, Chord, Ellipse, Line, Pie, Pipe, Polygon, Rectangle, Text

Control Levels Available:  None,   Advanced

Defaults to:  None

The default control level is "None".  In this case, "None" means that no scale factor has been applied.  This is equivalent to saying that the object is scaled to 100% of the size it was drawn.

 

Note that the menu provides 5 ways that the object can be scaled: Left, Bottom, Right, Top and Overall.  For the first four options, each refers to which side of the object will be adjusted in response to a change in scale factor.  In the case of "Overall", the entire object will scale relative to its center point.

 

A change in scale does not affect the number of pixels used to draw an object's outline.  The thickness used for the outline will remain un-affected by a scale change unless the outline's width is also controlled by the same tag or expression.  This can result in outlines which look out of proportion to the rest of the object if there is a large variation in the object's size.  Refer to the section, VTS Graphic Editor: Advanced Outline Properties, for more information on adjusting the outline width.

 

 

If the tag's value changes over a larger range than you would like the object to change, you can apply your own scaling factor to the tag's values with the Minimum Value and Maximum Value fields.
