Measures a specified text object, and returns the diagonal coordinates of a box that encloses the text
(textbox elist)
Arguments
An entity definition list defining a text object, in the format returned by entget.
If fields that define text parameters other than the text itself are omitted from elist, the current (or default) settings are used.
The minimum list accepted by textbox is that of the text itself.
Return Values
A list of two points, if successful; otherwise nil.
The points returned by textbox describe the bounding box of the text object as if its insertion point is located at (0,0,0) and its rotation angle is 0. The first list returned is generally the point (0.0 0.0 0.0) unless the text object is oblique or vertical, or it contains letters with descenders (such as g and p). The value of the first point list specifies the offset from the text insertion point to the lower-left corner of the smallest rectangle enclosing the text. The second point list specifies the upper-right corner of that box. Regardless of the orientation of the text being measured, the point list returned always describes the lower-left and upper-right corners of this bounding box.
Examples
The following command supplies the text and accepts the current defaults for the remaining parameters:
Command: (textbox '((1 . "Hello world.")))
((0.000124126 -0.00823364 0.0) (3.03623 0.310345 0.0))
