xclip Scilab Group Scilab Function xclip
NAME
xclip - set a clipping zone
CALLING SEQUENCE
xclip([x,y,w,h])
xclip(rect)
xclip("clipgrf")
PARAMETERS
x,y,w,h : real values.
rect : row vector of size 4.
DESCRIPTION
xclip set a clipping zone given by the coordinates, in the current
graphics scale, of the rectangle x,y,w,h (upper-left point, width,
height). If only one argument is given, it stands for a rectangle
specification rect=[x,y,w,h].
xclip("clipgrf") is used to clip the usual rectangle boundaries.
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))
// rectangle clipping zone
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 rectangle boundaries clipping zone
xbasc(); plot2d([-100,500],[-100,600],[-1,-1],"022")
xclip("clipgrf")
xsegs(10*x1+200*ones(x1),10*y1+200*ones(y1));
// clipping of
xclip()
