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,[zup],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
-
"clipgrf"
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 6])=[2 270*64];
xfarc(-.5,1,.4,.6,0,360*64);
arc.visible="off";
