Scilab Function

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()`.

### Examples

    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()
