Text descriptors appear in every Variable, and also in other places (cell instances and exports). All text descriptors have an anchor factor ("D0" through "D9"). If the anchor starts with a lower-case "d", the text is hidden (but the descriptor information is remembered). Here are the fields of a text descriptor:

A <size> ; | Text is absolute size (in points).
B | Text is bold.
C <color> ; | Text is drawn in the color index given.
D0 / d0 | Text is anchored at its center, limited to the size of its owner.
D1 / d1 | Text is anchored at its lower-left.
D2 / d2 | Text is anchored at its bottom.
D3 / d3 | Text is anchored at its lower-right.
D4 / d4 | Text is anchored at its left.
D5 / d5 | Text is anchored at its center.
D6 / d6 | Text is anchored at its right.
D7 / d7 | Text is anchored at its upper-left.
D8 / d8 | Text is anchored at its top.
D9 / d9 | Text is anchored at its upper-right.
F <font> ; | Text is shown in the named font.
G <size> ; | Text has relative size (in grid units).
H | Variable is inheritable (only for variables on Cells or Exports).
I | Text is italic.
L | Text is underlined.
N | Variable is written in the form "NAME=VALUE".
OJ | Text is Java code.
OL | Text is Spice code.
OT | Text is TCL code.
P | Variable is a parameter.
R | Text is rotated 90 degrees.
RR | Text is rotated 180 degrees.
RRR | Text is rotated 270 degrees.
T | Text is interior (seen only when inside the cell).
UR | Value is in Resistance units.
UC | Value is in Capacitance units.
</TRBR>
UI | Value is in Inductance units.
UA | Value is in Current units.
UV | Value is in Voltage units.
UD | Value is in Distance units.
UT | Value is in Time units.
X <xoff> ; | Text is offset in X from object center.
Y <yoff> ; | Text is offset in Y from object center.

Example:

`D4G8;`

The text is anchored on the left ("D4") and is 8 units tall ("G8;").
