THPDFPage

Draws an arc along the perimeter of the ellipse bounded by the specified rectangle.

Delphi syntax:

function DrawArc( X1, Y1, X2, Y2, X3, Y3, X4, Y4: Single ):TCurrPoint;

C++ syntax:

TCurrPoint __fastcall DrawArc( float X1, float Y1, float X2, float Y2, float X3, float Y3, float X4, float Y4 );

Description

Use DrawArc to draw an elliptically curved line. The arc traverses the perimeter of an ellipse that is bounded by the points (X1,Y1) and (X2,Y2). The arc is drawn following the perimeter of the ellipse, counterclockwise, from the starting point to the ending point. The starting point is defined by the intersection of the ellipse and a line defined by the center of the ellipse and (X3,Y3). The ending point is defined by the intersection of the ellipse and a line defined by the center of the ellipse and (X4, Y4).
