WG - Fill Wedge
WG r , q1 , qc (, qd )[;]
r ; Radius in current 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.
• You should use this command with the type "isotropic". Anisotropic type may make the wedge stretch.
• r specifies the radius of circle. A positive value places the 0° reference point onto the positive x-axis and
the negative value places it onto the negative x-axis.
• The value for q1 is a clamped real number.
• q1 specifies the wedge starting point related to the 0° reference point.
• 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.
• qc specifies the angle of the wedge.
• The value for qc is a clamped real number.
• Plotting proceeds counterclockwise when qc is positive, and clockwise when negative.
• The value for qd is a clamped real number.
• When qd is not specified, the chord angle is the default value ( 5 degrees ).
