Remarks:

Special care must be taken, when creating VPE Document files that contain pictures or UDO's.
For details please see WriteDoc.

 

VPE offers several methods to attach an object's position to margins and relative to the position of previously inserted objects. In addition Text, Rich Text and Picture objects are able to compute their dimensions automatically depending on their visual content.
