A string representation of a Double value. This is interpreted as a device-independent unit (1/96th inch) measurement. Strings need not explicitly include decimal points. For example, a value of 1 is acceptable.
The same Double range restrictions that are mentioned in the Property Value section apply here.
A double value as previously described that is followed by one of these unit declaration strings: px, in, cm, pt.
px (default) is device-independent units (1/96th inch per unit)
in is inches; 1in==96px
cm is centimeters; 1cm==(96/2.54) px
pt is points; 1pt==(96/72) px
Note In many cases a double may be set to "Auto," but a Control::FontSize does not render if set to "Auto".
