I am struggling a bit with the fontsize  in flowchart.

In my form the user can select a new font size for the active object by selecting a value from a toolstripxombobox. The value is given in Points, e.g. 10 as the default value. The measureunit of flowchart is Millimeter. To assign the fontsize to the currently selected object I do the following:

defaultFontSize = size * PointToMM; //PointToMM = 0.35
if (btChart.ActiveObject.GetType() == typeof(Box))
{

Font font = new Font(defaultFontfamily, defaultFontSize, GraphicsUnit.World);

(btChart.ActiveObject as Box).Font = font;

font.Dispose();
}
 

First I convert the selected fontsize by 0.35 to convert it from Points to Millimeter. Then I create a new font and assign it the object.
Is this the correct way to do it?

I am asking because if I compare the length of a given text in Arial 10 from flowchart to the same text in Powerpoint or Word, the text in flowchart is always some pixels shorter. Not much, but my understanding is, that all applications should show the same text with same font and size with the same length?!

Thanks, I will give it a try.

But one more question:
In boxes etc I use GraphicsUnit.World when creating fonts.

If I do the same with a RichTextBox that is included in a Controlhost this will not work. The Text comes out tiny.

(e.ControlHost.Control as RichTextBoxPrintCtrl).Font = new Font(GetDefaultFontFamily(), GetDefaultFontSize(), FontStyle.Regular, GraphicsUnit.World);
 

Only if I create the font with GraphicsUnit.Millimeter  the text has the same size as a box.

Is this a 'normal' behaviour of a RichTextBox or a Controlhost?
