Arc entity properties
Description
The Arc entity is a leaf of the graphics entities
hierarchy. This entity defines the parameters for ellipses and part
of ellipses and the filled ones.
visible:
This field contains the visible property value
for the entity . It should
be "on" or "off" . If "on"
the arc is drawn, If
"off" the arc is not displayed on the screen.
data:
This property is to return the coordinates of the upper-left point, the
width and the height of the inclosing rectangle as well as the
boundary angles of the sector. It is the matrix
[xleft,yup;width,height;a1,a2] where a1/64
and a2/64 are the sector boundary angles in degree.
line_style:
The line_style property value should be an integer in [0 9].
0 stands for solid the other value stands for a selection of
dashes.
thickness:
This field contains the line thickness property. Its value should
be positive integer.
foreground:
This field contains the default foreground property
value used to draw or to fill arc. It should be a color index
(relative to the current colormap).
fill_mode:
If fill_mode property value is "on" ,
the rectangle is filled with the foreground color,
if its value is "off" only the
shape of the arc is drawn using the foreground color.
clip_state:
This field contains the clip_state property
value for the arc. Clip_state value should be :
"off" this means that the arc is not clipped
"cliprf" this means that the
arc is clipped outside the Axes box.
"on" this means that the
arc is clipped outside the arc given by property clip_box.
clip_box:
This field is to determinate the clip_box property.
By Default 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 arc to display, however clip_state property
value will be changed.
parent:
This field contains the handle of the parent. The parent of the arc
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];
xarc(-1.5,1.5,3,3,0,360*64)
arc=get("hdl"); //get handle on current entity (here the arc entity)
arc.fill_mode="on";
arc.foreground=5;
arc.data(3,:)=[2 270*64];
arc.visible="off";
