WG - Fill wedge 

WG r,q1,qc(,qd)[;] 

r ; Radius in user units or graphics units  

q1 ; Start point angle 

qc ; Arc angle  

 

qd ; Chord angle 

 

 

Fill in a wedge centred on the current position with radius 

r

, start point angle 

q1

, arc angle 

qc

 and chord 

angle 

qd

 

After plotting, the cursor returns to its point of origin. 

 

Plotting is performed whether the pen is up or down. 

 

When scaling has been performed, the circle is plotted in user units. 

 

Also, when scaling has been performed, the value for r is a real number. 

 

When there is no scaling, the circle is plotted in graphics units. 

 

When there is no scaling, the coordinate value for r is an integer number. 

 

The value for 

q1

 is a clamped real number. 

 

When 

q1

 is positive, the positive direction of the X axis relative to the current position is set at 0 degrees and 

the start point is sought in the counterclockwise direction.  The opposite occurs when q1 is negative: the 
negative X axis is set at 0 degrees and the start point is sought by going clockwise. 

 

The value for 

qc

 is a clamped real number. 

 

Plotting proceeds counterclockwise when 

qc

 is positive and clockwise when it is negative. 

 

The value for 

qd

 is a clamped real number. 

 

When 

qd

 is not specified, the chord angle is the default value ( 5 degrees ).
