Draws an arc on a Draw surface.
Return Value
Return value not used.
Parameters
dr Handle to the Draw surface to be drawn on.
x The x coordinate of the center of the circle of the arc.
y The y coordinate of the center of the circle of the arc.
radius The radius of the circle, in pixels.
begin The angle, in degrees, where the arc should begin. Zero degrees describes the point that is at the x coordinate of the radius and radius pixels above the radius point.
end The angle, in degrees, at which the angle should end.
Remarks
DrawArc() draws an arc of a circle on the Draw surface.
Availability
Available in DragonFireSDK 1.3 and later.
Example
#include "DragonFireSDK.h"
int MyDraw;
void AppMain() { MyDraw = DrawAdd(0, 0, 320, 480); // Set up my draw colors and pen width... DrawSetColor(MyDraw, 0xFF0000); DrawSetFillColor(MyDraw, 0x00FF00FF); DrawSetPenWidth(MyDraw, 2); //Draw a line... DrawMoveTo(MyDraw, 10, 10); DrawLineTo(MyDraw, 20, 20); //Draw another line... DrawLine(MyDraw, 20, 20, 10, 20); //Draw a hollow circle... DrawCircle(MyDraw, 10, 50, 50, 50); //Draw a filled circle... DrawCircleFill(MyDraw, 10, 110, 50, 50); //Draw a hollow square... DrawSquare(MyDraw, 80, 50, 50, 50); //Draw a fillerd square... DrawSquareFill(MyDraw, 80, 110, 50, 50); //Draw an arc... DrawArc(MyDraw, 140, 75, 25, 0, 90); }
