TCrown Class Reference

To draw a Crown.

A crown is specified with the position of its centre, its inner/outer radius a minimum and maximum angle. The attributes of the outline line are given via TAttLine. The attributes of the fill area are given via TAttFill.

Example:

{
TCanvas *c1 = new TCanvas("c1","c1",400,400);
TCrown cr1(.5,.5,.3,.4);
cr1.SetLineStyle(2);
cr1.SetLineWidth(4);
cr1.Draw();
TCrown cr2(.5,.5,.2,.3,45,315);
cr2.SetFillColor(38);
cr2.SetFillStyle(3010);
cr2.Draw();
TCrown cr3(.5,.5,.2,.3,-45,45);
cr3.SetFillColor(50);
cr3.SetFillStyle(3025);
cr3.Draw();
TCrown cr4(.5,.5,.0,.2);
cr4.SetFillColor(4);
cr4.SetFillStyle(3008);
cr4.Draw();
return c1;
}
