# xstringl

compute a box which surrounds strings

### Syntax

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. For more information, see graphics_fonts

fontSize

an integer specifying the font size. For more information, see graphics_fonts

### 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

plot2d([0, 1], [0, 1], 0);
str = ["$\underleftrightarrow{Scilab}$" "is"; "not" "elisaB"]; // Only valid from Scilab 5.2
r = xstringl(0.5, 0.7, str);
xrects([r(1) r(2)+r(4) r(3) r(4)]');
xstring(r(1), r(2), str);

str = ["Scilab" "is"; "not" "Matlab"];
r2 = xstringl(0.2, 0.2, str, 5, 7);
xrects([r2(1) r2(2)+r2(4) r2(3) r2(4)]');
xstring(r2(1), r2(2), str)
