Measuring the exact size of a string

Hi all,

I want to write a function that gets the following parameters:

a string "s"
a font "f"

and returns the EXACT width and height of the font.

I tried first with MeasureString but it adds me extra space;
then I tried with MeasureCharacterRanges but I didn't manage
to get rid of an extra space.

I need to have a pair of values that could enable me to draw,
let's say, a bounding box that TOUCHES the string on every border,
no matter how the glyphs are shaped (f.ex. a string with only
a period, ".", should return a very small b.box instead of taking
account of the extra space OVER the dot).

Thanks for your help!
 
Text measurements always include spacing pixels all around, as
determined by the font. AFAIK the only reliable way to determine the
actual pixels occupied by a text string is to render it to a memory
device, then scan from each side until you see a non-white pixel.

Yes, I had already figured out this technique, but I hoped
to avoid it as it seems so unelegant ... Thanks, anyway!
