Example of drawing a full ellipse (from 0, 360) and outputting it as a PNG.
Do note, that this is by default anti-aliased unlike the GD functions which only support it on
lines that aren't on a transparent background.
<?php
$width = 200;
$height = 100;
$border = 2;
$img = new Imagick();
$img->newImage( $width, $height, new ImagickPixel( 'transparent' ) );
$draw = new ImagickDraw();
$draw->setStrokeColor( new ImagickPixel( 'black' ) );
$draw->setStrokeWidth( 2 );
$draw->setFillColor( new ImagickPixel( 'transparent' ) );
//Substract the border from the radius so it doesn't fall outside the screen.
$draw->ellipse( $width/2, $height/2, ($width/2)-$border, ($height/2)-$border, 0, 360 );
$img->drawImage( $draw );
$img->setImageFormat( "png" );
header( "Content-Type: image/png" );
echo $img;
?>
