String representation of a Double value in the range 0.0034 to 160000. An unqualified value is measured in device independent pixels. Strings need not explicitly include decimal points.
A double value as described above, (excepting Auto) followed by one of the following unit specifiers: 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
Causes the line height to be determined automatically from the current font characteristics. Equivalent to a property value of Double.NaN.
Type: System.Double The height of each line in device independent pixels with a value range of 0.0034 to 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.
