===== Pie (Statement) =====

==== Format ====

**pie** [[numericexpressions|x_position]], [[numericexpressions|y_position]], [[numericexpressions|width]], [[numericexpressions|height]], [[numericexpressions|start_angle]], [[numericexpressions|width_angle]]\\
**pie** ( [[numericexpressions|x_position]], [[numericexpressions|y_position]], [[numericexpressions|width]], [[numericexpressions|height]], [[numericexpressions|start_angle]], [[numericexpressions|width_angle]] )\\
**pie** [[numericexpressions|center_x_position]], [[numericexpressions|center_y_position]], [[numericexpressions|radius]], [[numericexpressions|start_angle]], [[numericexpressions|width_angle]]\\
**pie** ( [[numericexpressions|center_x_position]], [[numericexpressions|center_y_position]], [[numericexpressions|radius]], [[numericexpressions|start_angle]], [[numericexpressions|width_angle]] )


==== Description ====

Draws a pie shaped slice inside the rectangle defined by a bounding rectangle (defined by [[numericexpressions|x_position]], [[numericexpressions|y_position]], [[numericexpressions|width]], and [[numericexpressions|height]]) or by a square bounding a circle (defined by [[numericexpressions|center_x_position]], [[numericexpressions|center_y_position]], [[numericexpressions|radius]]).  The angles are defined from the 12 o'clock position in a clockwise direction in radians.
