xclip(2) Scilab Function xclip(2)
NAME
xclip - set a clip zone
CALLING SEQUENCE
xclip([x,y,w,h])
xclip(rect)
xclip("clipgrf");
PARAMETERS
x,y,w,h : four float values
rect : a vector of size (1,4)
DESCRIPTION
Sets a clip region given by the coordinates, in the current graphic scal-
ing, of a rectangle (x,y,w,h) (Upper-Left point,Width aba Height). If only
one argument is used it stands for a rectangle specification
rect=[x,y,w,h].
xclip("clipgrf") is used to clip the usual graphic rectangle.
To unclip a region use the command xclip()
EXAMPLE
x=0:0.2:2*%pi;
x1=[sin(x);100*sin(x)];
y1=[cos(x);100*cos(x)];
y1=y1+20*ones(y1);
// No clip
plot2d([-100,500],[-100,600],[-1,-1],"022");
xsegs(10*x1+200*ones(x1),10*y1+200*ones(y1));
xbasc()
//
// Rect clip
xbasc();plot2d([-100,500],[-100,600],[-1,-1],"022");
xrect(150,460,100,150);
xclip(150,460,100,150);
xsegs(10*x1+200*ones(x1),10*y1+200*ones(y1));
//
// usual graphic rectangle clip
xbasc();plot2d([-100,500],[-100,600],[-1,-1],"022");
xclip("clipgrf");
xsegs(10*x1+200*ones(x1),10*y1+200*ones(y1));
// clipping off
xclip()
