patch_properties — description of the Patch entity properties

Description

A patch is a filled polyline. The Patch entity is a leaf of the graphics entities hierarchy. This entity defines the parameters for patchs.

visible: This field contains the visible property value for the entity . It should be "on" or "off" .By default, the patch is visible, the value's property is "on". If "off" the patch is not drawn on the screen.

data: This field contains the boundary values for the x and y coordinates. It is a two column matrix [x,y] of points.

foreground: This field contains the default foreground property used to draw of the patch. Its value should be a color index (relative to the current colormap).

clip_state:

This field contains the clip_state property value for the patch. Its value should be :

	`"off"` this means that the patch is not clipped.
	`"cliprf"` this means that the portion of the patch outside the axes box is not displayed.
	`"on"` this means that the patch is clipped outside the rectangle given by property clip_box.

clip_box: This field is to determinate the clip_box property. Its value should be an empty matrix if clip_state is "off". Other cases the vector [x,y,w,h] (upper-left point width height) defines the portions of the patch to display, however clip_state property value will be changed.

parent: This property contains the handle of the parent. The parent of the patch entity should be of the type "Axes" or "Agregation".

Examples


             
  
  set("figure_style","new") //create a figure
   a=get("current_axes");//get the handle of the newly created axes
   a.data_bounds=[-2,-2,2,2];

   xfpoly(sin(2*%pi*(0:5)/5),cos(2*%pi*(0:5)/5))
   p=get("hdl"); //get handle on current entity (here the pacth entity)
   p.foreground=14;
   p.data=[(-2:0.1:2)' sin((-2:0.1:2)*%pi)']
   p.clip_box=[-2, .5, 4,1]
   p.clip_state
   p.clip_state="off";
