Is there a way to determine what the size of a GDI+ string output would be
prior to drawing?

For example, If I have something like this:
Dim fnt As New Font("Times", 12)
Dim drawFormat As New StringFormat
drawFormat.LineAlignment = StringAlignment.Center
drawFormat.Alignment = StringAlignment.Center
g.DrawString("ABC", fnt, New SolidBrush(color.black), X1, Y1, drawFormat)

This would draw ABC horizontally & vertically centered the X1,Y1 point. The
problem is that is may be drawn off the edge of the screen, especially if it
were a long string. It would be great to know what the rectangular size is
prior to drawing.

Thanks!

Rob,
You can use Graphics.MeasureString to get the size.

> drawFormat.Alignment = StringAlignment.Center

Dim sz As Size = g.MeasureString("ABC", ...)

> g.DrawString("ABC", fnt, New SolidBrush(color.black), X1, Y1, drawFormat)

Hope this helps
Jay

try g.MeasureString()
(assuming g is the Graphics object)

Thanks Jay and Daniel....I knew it had to be something fairly simple...I was
searching for something related to "size"...not "measure"

'Graphics.MeasureString' (and maybe 'Graphics.MeasureCharacterRanges').

Hey Rob,

The Graphics.MeasureString() returns a SizeF object.
