10-4: Miscellaneous
10-4-2: Text Descriptors

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 upper-right.
D2 / d2	Text is anchored at its top.
D3 / d3	Text is anchored at its upper-left.
D4 / d4	Text is anchored at its right.
D5 / d5	Text is anchored at its center.
D6 / d6	Text is anchored at its left.
D7 / d7	Text is anchored at its lower-right.
D8 / d8	Text is anchored at its bottom.
D9 / d9	Text is anchored at its lower-left.
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.
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;").
