Visio add-in getting the font size of shape's text

Question

I'm trying to determine the size of the font of a shape's text. When I use Visio as a user, I can see this value in the Shape sheet (under Character->size) However I'm not able to understand how to access it programatically, for reading.

Which section, Row and Cell indexes should I use? Or maybe use the Characters object of the shape?

Answer 1

I was successful in obtaining the formula by:

string fontSize = shape.CellsSRC[(short) Visio.VisSectionIndices.visSectionCharacter,
      (short) Visio.VisRowIndices.visRowCharacter,
      (short) Visio.VisCellIndices.visCharacterSize].Formula;

Or by:

string fontSize = shape.CellsSRC[3,0,7].Formula;

Which is practically the same, only not very readable, Or by:

string fontSize = shape.get_Cells("Char.Size").Formula;
