ApplicationSettings.StencilLinesPerMaster Property (Visio)
For shapes on stencils in Microsoft Visio, determines how many lines of text of each shape's name can appear below the shape before the text is truncated and "..." is appended. Read/write.
Setting the StencilLinesPerMaster property is equivalent to setting the Lines per master option under Stencil spacing on the Advanced tab in the Visio Options dialog box (click the File tab, and then click Options).
The minimum value for StencilLinesPerMaster is 1 line per master and the maximum is 4. By default, Visio displays 2 lines per master.
This property affects the overall spacing of shapes on a stencil, which affects how many shapes users can see without scrolling.
This Microsoft Visual Basic for Applications (VBA) macro shows how to use the StencilCharactersPerLine property to print the current number of stencil lines per master in the Immediate window. It also shows how to get an ApplicationSettings object from the Visio Application object.
