Hi, I want to get the font size of the resized TextVobject? I was try with following code, but it still get the font size before TextVobject resize.

If TypeOf obj Is Aurigma.GraphicsMill.WinControls.TextVObject Then
Dim txtObj As Aurigma.GraphicsMill.WinControls.TextVObject = CType(obj, Aurigma.GraphicsMill.WinControls.TextVObject)
MsgBox (txtObj.Font.Size)
End If


Thanks in advance.

Hello,

TextObject resize doesn't affect on the FontSize directly. It just changes VObject transformation matrix, therefore you should calculate scale coefficient and multiply it with TextObject.Font.Size value. Here is code sample to illustrate the idea:

Code:
private static float CalcDistance(System.Drawing.PointF p0, 
	System.Drawing.PointF p1)
{
	float dx = p0.X - p1.X;
	float dy = p0.Y - p1.Y;
	return (float)Math.Sqrt(dx * dx + dy * dy);
}

private static float GetVerticalScale(
	Aurigma.GraphicsMill.WinControls.IVObject obj)
{
	System.Drawing.PointF[] pnts = new System.Drawing.PointF[] {
		new System.Drawing.PointF(0, 0),
		new System.Drawing.PointF(0, 1)};

	obj.Transform.TransformPoints(pnts);
	return CalcDistance(pnts[0], pnts[1]);
}

private void TestTextFontSize()
{
	Aurigma.GraphicsMill.WinControls.TextVObject textObj = 
		<... get object from somewhere... >;
	System.Windows.Forms.MessageBox.Show(
		(textObj.Font.Size * GetVerticalScale(textObj)).ToString());
}
