compute a box which surrounds strings
rect=xstringl(x,y,str,[fontId,fontSize])
vector of 4 real scalars defining the box.
real scalars, coordinates of the lower-left point of the strings.
matrix of strings.
Starting from Scilab 5.2, it is possible to write LaTeX or MathML expression.
an integer specifying the font type. For more information, see graphics_fonts
an integer specifying the font size. For more information, see graphics_fonts
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.
