TextRectOffset
Within a rich edit control (encapsulated by DigaRTF) a rectangle can be set, in which the text is being displayed. With this parameter you can define how many pixels should stay empty on each side of the text, so you can define the rim for each side. Format is "Left,Top,Right,Bottom". To have a rim on the left and right side use e.g. "30,0,30,0".
Possible values:
Default value: 0,0,0,0
