Unfortunately it won't work in all cases. Using a field with the text
set to "1" and the textfont set to "webdings" is a good test case.
The problem is that even though you may have the textsize set to 100,
the vertical space taken up by the character is only 70 pixels (on my
Mac). Other characters in the font might take up more or less
While webdings isn't a font that will be used in what I'm doing it
does illustrate the problem nicely. The textsize of a char does not
return the actual vertical space taken up by the char so it makes it
difficult to find the exact center of text that is being displayed.
