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