stringbox - Compute the bounding rectangle of a text or a label.

Calling Sequence

rect = stringbox( string, x, y, [angle, [fontStyle, [fontSize]]] )
rect = stringbox( Handle )

Parameters

Description

stringbox returns the bounding rectangle vertices of a text or label object or a string which will be displayed with a certain way. the coordinates are given with the current graphic scale. the first vertex correspond to the text coordinates (x,y), the lower left point without rotation, the following vertex are given clockwise in the resulting matrix.

The result migth not be very accurate with PostScript driver.

Examples

// show axes
axes = gca() ;
axes.axes_visible = 'on' ;
axes.data_bounds = [ 1, 1 ; 10, 10 ] ;

// display a labels for axes
xtitle( 'stringbox', 'X', 'Y' )  ;

// get the bounding box of X label
stringbox( axes.x_label )

// draw a string
str = [ "Scilab", "is" , "not", "Skylab" ] ;
xstring( 4, 9, str ) ;

//modify the text
e = gce() ;
e.font_angle = 90 ;
e.font_size    = 6  ;
e.font_style   = 7 ;
e.box = 'on' ;

// get its bounding box
stringbox( e )
// or
rect = stringbox( str, 4, 9, 90, 6, 5 )

// click and find if the text was hit
hit = xclick()  ;
hit = hit( 2 : 3 ) ;

if hit(1) >= rect(1,1)  & hit(1) <=  rect(1,2) & hit(2) <= rect(2,2) & hit(2) >= rect(2,3) then
  disp('You hit the text.') ;
else
  disp('You missed it.')
end;
