There is another way to fill an arc :



<?php

// To draw the arc

$Color = imagecolorallocate($Image, $Red, $Green, $Blue);

imagearc($Image, $CenterX, $CenterY, $Diameter, $Diameter, $Start, $End, $Color);

// To close the arc with 2 lines between the center and the 2 limits of the arc

$x = $CenterX + (cos(deg2rad($Start))*($Diameter/2));

$y = $CenterY + (sin(deg2rad($Start))*($Diameter/2));

imageline($Image, $x, $y, $CenterX, $CenterY, $Color);

$x = $CenterX + (cos(deg2rad($End))*($Diameter/2));

$y = $CenterY + (sin(deg2rad($End))*($Diameter/2));

imageline($Image, $x, $y, $CenterX, $CenterY, $Color);

// To fill the arc, the starting point is a point in the middle of the closed space

$x = $CenterX + (cos(deg2rad(($Start+$End)/2))*($Diameter/4));

$y = $CenterY + (sin(deg2rad(($Start+$End)/2))*($Diameter/4));

imagefilltoborder($Image, $x, $y, $Color, $Color);

?>
