xstringl
compute a box which surrounds strings
Calling Sequence
rect=xstringl(x,y,str,[fontId,fontSize])
Arguments
- rect
vector of 4 real scalars defining the box.
- x,y
real scalars, coordinates of the lower-left point of the strings.
- str
matrix of strings.
Starting from Scilab 5.2, it is possible to write LaTeX or MathML expression.
- fontId
an integer specifying the font type.
- fontSize
an integer specifying the font size.
Description
xstringl returns in rect=[x,y,w,h]
(upper-left point, width, height) the size of a rectangle in the current
graphic scale which would surround the strings str drawn at
location x,y (lower-left point).
The result can be approximative when using the Postscript driver.
Examples
