A string representation of a Double value. This value is interpreted as a device-independent unit (1/96th inch) measurement. Strings need not explicitly include decimal points. For example, you can specify a value of 1.
The same Double range restrictions as mentioned in the Property Value section apply here.
A double value 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
An automatic line height determination. If you programmatically set the Auto value, its value corresponds to Double.NaN.
Type: System.Double A double that specifies the height of each line box. This value must be equal to or greater than 0.0034 and equal to or less then 160000. A value of Double.NaN (equivalent to an attribute value of Auto) causes the line height to be determined automatically from the current font characteristics. The default is Double.NaN.
