Description
Draws an arc as the part of an ellipse contour on the TCanvas.
The arc is created as a path containing the part of an ellipse contour. DrawArc draws this path on the current TCanvas with the current Stroke parameters.
The Center parameter specifies the center of the ellipse.
The coordinates of the Radius parameter specify the semi-axes of the parent ellipse:
Radius.xdefines the x-semi-axis.Radius.ydefines the y-semi-axis.
StartAngle specifies the angle, in degrees, measured clockwise, from the x-axis to the line passing through the Center point of the ellipse and intersects the ellipse in the starting point of the arc.
SweepAngle specifies the angle, in degrees, measured clockwise, from the StartAngle parameter to the line passing through the Center point of the ellipse and intersects the ellipse in the ending point of the arc.
The AOpacity parameter specifies the transparency of the Stroke color.
To customize the drawing pen, use the Stroke, Thickness, Cap, Dash , and Join properties.
