Draw circle with php imagemagick

I just want to get a basic idea on how to draw a circle using php5 imagemagick. I've looked at the page, http://php.net/manual/en/imagickdraw.circle.php but the example is too confusing. I just want to draw a circle and then have a chat with it. Can anyone give me a simple php5 imagemagick circle example?

I tried:

<?php
header("Content-type: image/jpeg");
$circle = new ImagickDraw();
$draw->circle (10, 10, 60, 10);
//echo $circle;
?>

any numerous options, but I can't get the circle.

Danak on the php chat page provided me with this link which provides an active example. http://www.phpimagick.com/ImagickDraw/circle

Variable names are short and descriptive, and this example makes it easier for me to understand what's going on.



function circle($strokeColor, $fillColor, $backgroundColor, $originX, $originY, $endX, $endY) {

    //Create a ImagickDraw object to draw into.
    $draw = new \ImagickDraw();

    $strokeColor = new \ImagickPixel($strokeColor);
    $fillColor = new \ImagickPixel($fillColor);

    $draw->setStrokeOpacity(1);
    $draw->setStrokeColor($strokeColor);
    $draw->setFillColor($fillColor);

    $draw->setStrokeWidth(2);
    $draw->setFontSize(72);

    $draw->circle($originX, $originY, $endX, $endY);

    $imagick = new \Imagick();
    $imagick->newImage(500, 500, $backgroundColor);
    $imagick->setImageFormat("png");
    $imagick->drawImage($draw);

    header("Content-Type: image/png");
    echo $imagick->getImageBlob();
}

Hope this is what you are looking for:



<?php
$draw = new ImagickDraw ();
//given that $x and $y are the coordinates of the centre, and $r the radius:
$draw->circle ($x, $y, $x + $r, $y);
?>
