[Scilab-users] example for xstringl fontId argument with latex-rendered strings

[Philipp Mühlmann]

the "2" stands for the font ID...hence you should be able to change
font style by entering a different number there..see the help page

The $-sign in the str = (...) defines that the string is drawn in LaTeX mode.

note that there are at least two modes to write LaTeX

- a text mode
- a math mode

using just  the $-sign will enable LaTeX format but in math mode.
hence white space won't be drawn


using "$\mbox{}$" enables LaTeX mode (the $-sign), but now everything
that is written in between the brackets of \mbox{} is written in text
mode...hence white space is also drawn.


You may try following example code:
As you may recognize I used the gce() command to change the font style.
I do this because changing the font style within xstringl() somehow
doesn't work for me.




plot2d([0;1],[0;1],0);
// Only valid from Scilab 5.2

str1=["simple text"] ;

str2=["$\mbox{LaTeX format in text mode}$" ; "" ; "" ; "$LaTeX format
in mathmode$"] ;


r1 = xstringl(0.1,0.1,str1,2,4);
r2 = xstringl(0.1,0.4,str2);

xrects([r1(1) r1(2)+r1(4) r1(3) r1(4)]');       // computes rectangle
around string
xstring(r1(1),r1(2),str1);

xrects([r2(1) r2(2)+r2(4) r2(3) r2(4)]');       // computes rectangle
around string
xstring(r2(1),r2(2),str2);

// use just xstring

xstring(0.5,0.2,str2,0,1);       // computes as well rectangle around
string, since angle = 0 deg
xstring(0.5,0.5,str2,0,0);      // no rectangle asince bounding box value = 0

xstring(0.5,0.7,str2,-10,1);    // no rectangle around string since
angle = -45deg
e = gce();
e.font_style = 2;
e.font_size = 4;
e.box = 'on' ;

xstring(0.5,0.1,str1);
e = gce();
e.font_style = 2;
e.font_size = 4;
e.box = 'on' ;
