MeasureString - Slighly narrower than actual text.

Phil Jones

When I use the MeasureString method of the [Graphics] object to determine
the size that a string will take up when rendered - the method returns a
Size that has a width slightly narrower than the actual string.

By this I mean that if I paint the string within the returned size bounds it
falls off the end, or an ellipsus is displayed (if trimming is set
appropriately).

Is this by design?? Is there a standard way to correct this, or what should
I do? At the moment I'm increasing the width by the point-size of the font,
but that seems a bit dodgy to me.

Thanks for any advice...

When you use MeasureString you must use the same TextRenderingHint in the
Graphics object as you do when you draw it. Even then, the most accurate
method is to measure using TextRenderingHint.Antialias.

Thanks Bob - now that you point it out it makes sense that the
TextRenderingHint would have an effect on size.

Cheers,
