[Circle Shader] [AYUDA]

[Looney;3]

Holus nececito ayuda para saber como solucionar el Circle Shader, porque sale pixelado

  
function dxDrawCircle( x, y, width, height, color, angleStart, angleSweep, borderWidth ) 
    height = height or width 
    color = color or tocolor(255,255,255) 
    borderWidth = borderWidth or 1e9 
    angleStart = angleStart or 0 
    angleSweep = angleSweep or 360 - angleStart 
    if ( angleSweep < 360 ) then 
        angleEnd = math.fmod( angleStart + angleSweep, 360 ) + 0 
    else 
        angleStart = 0 
        angleEnd = 360 
    end 
    x = x - width / 2 
    y = y - height / 2 
    if not circleShader then 
        circleShader = dxCreateShader ( "files/circle.fx" ) 
    end 
    dxSetShaderValue ( circleShader, "sCircleWidthInPixel", width ); 
    dxSetShaderValue ( circleShader, "sCircleHeightInPixel", height ); 
    dxSetShaderValue ( circleShader, "sBorderWidthInPixel", borderWidth ); 
    dxSetShaderValue ( circleShader, "sAngleStart", math.rad( angleStart ) - math.pi ); 
    dxSetShaderValue ( circleShader, "sAngleEnd", math.rad( angleEnd ) - math.pi ); 
    dxDrawImage( x, y, width, height, circleShader, 0, 0, 0, color ) 
end
