stringbox

Compute the bounding rectangle of a text or a label.

Syntax

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

Arguments

rect

a 2x4 matrix containing the 4 vertex coordinates of the bounding rectangle.

string

string matrix to be enclosed.

x,y

real scalars, coordinates of the lower left point of strings.

angle

Rotation angle of the string clockwise and in degrees around the (x,y) point.

fonStyle

integer specifying the type of the font.

fontSize

integer specifying the size of the font.

Handle

a graphic handle of Text or Label type.

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 might 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, 7, 6 )

// 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;
