arc_properties - description of the 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.
-
parent: This field contains the handle of the parent. The parent of the
arc entity should be of the type "Axes" or
"Compound".
-
children: This property contains a vector with the children of
the handle. However, arc handles currently do not have
any children.
-
thickness: This field contains the line thickness property. Its
value should be positive integer.
-
line_style: The line_style property value should be an integer in
[1 6]. 1 stands for solid the other value stands for a selection of
dashes.
-
line_mode: This property allows to display or not the line representing the
arc. The value must be "on" or "off".
-
fill_mode: If fill_mode property value is "on" ,
the arc is filled with the background color.
-
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).
-
background: This field contains the color used to fill the arc. It should be a
color index (relative to the current colormap).
-
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.
-
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.
-
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.
-
user_data: This field can be use to store any scilab variable in the arc data
structure, and to retreive it.
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";
