SvgGraphics2D.DrawArc

SvgGraphics2D.DrawArc method

Draws an arc representing a portion of an ellipse specified by a Rectangle structure.

public void DrawArc(Pen pen, Rectangle rect, float startAngle, float arcAngle)

Parameter	Type	Description
pen	Pen	The pen to draw the outline of the figure.
rect	Rectangle	The boundaries of the ellipse.
startAngle	Single	The angle in degrees measured clockwise from the x-axis to the starting point of the arc.
arcAngle	Single	The angle in degrees measured clockwise from the startAngle parameter to ending point of the arc.

This example shows how to create an SVG image of the specified size and draw different shapes on it using SvgGraphics2D.
