Alignment and location

The alignment or justification of the text is controlled by the keyword `TEXTALIGN`. The origin of the text is always the lower left corner of the string. The alignment determines where this origin is placed with respect to a reference point. See the figure and the table below. The default value of `TEXTALIGN` is 1 (the origin is the same as the reference point).

If `TEXTINTERACTIVE ≠ 0`, then the graphics cursor is used to interactively determine the reference point to place a text string when drawn by the `TEXT` command.

If `TEXTINTERACTIVE = 0`, then `XTEXTLOCATION` and `YTEXTLOCATION` will be used to determine the reference point for the character string.

(x0,y0) | origin point of string (lower left corner)
(xref,yref) | reference point
H | maximum height of string
L | length of string
a | angle of string in degrees
`1` | x0 = xref | y0 = yref
`2` | x0 = xref - L/2 | y0 = yref
`3` | x0 = xref - L | y0 = yref
`4` | x0 = xref | y0 = yref - H/2
`5` | x0 = xref - L/2 | y0 = yref - H/2
`6` | x0 = xref - L | y0 = yref - H/2
`7` | x0 = xref | y0 = yref - H
`8` | x0 = xref - L/2 | y0 = yref - H
`9` | x0 = xref - L | y0 = yref - H
`10` | x0 = xref | y0 = yref a = 90°
`11` | x0 = xref | y0 = yref a = 270°
`12` | x0 = xref - L/2 | y0 = yref a = 90°
