Example #1 Using Imagick::newImage():
Create a new image and display it.
<?php
$image = new Imagick();
$image->newImage(100, 100, new ImagickPixel('red'));
$image->setImageFormat('png');
header('Content-type: image/png');
echo $image;
?>

As it isn't obvious, the cols and rows arguments correspond to the width and height of the new image, expressed in pixels. Example #1 would generate a 100 pixel by 100 pixel image.
