Drawing GeneralNote MeasureText

[bLennitz]

I need assistance with portion of drawing routine.  I need to determine size of GeneralNote before placing note to my sheet.  My notes are single or multi-line notes depending on length of note.  I need to determine length to know if note will break to multi-line.  I did not find function in Inventor API to get value.  I cannot place note and move it.  I must know position prior to placing to sheet.

I attempted use of .NET function `System.Windows.Forms.TextRenderer.MeasureText()`, but it seems Inventor calculates text size differently.

My trials are included;

?System.Windows.Forms.TextRenderer.MeasureText("XXXXXX", New System.Drawing.Font("ARIAL", 72))
{Width = 543 Height = 134}
    Empty: {Width = 0 Height = 0}
    Height: 134
    height: 134
    IsEmpty: False
    Width: 543
    width: 543

When I perform math to convert pixels to inches to centimeters I get following
--I divide 120 which is from this.CreateGraphics().DpiX to convert pixels to inches
--I multiply 2.54 to convert inches to centimeters
543 / 120 * 2.54
Width = 11.4935
134 / 120 * 2.54
Height = 2.836333

I use same values for my GeneralNote;

FormattedText=<StyleOverride Font='Arial' FontSize='2.54'>XXXXXX</StyleOverride>
LineSpacing=1
WidthScale=1

RESULTS...

Height=2.5399999618530273
Width=14.206189155578613

As you see there is significant difference in text size calculated via .NET and GeneralNote.  Does any one have an idea?

Thank you
