String representation of a Double value equal to or greater than 0.0034 and equal to or less then 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, in the range 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.
