Basic usage

Imagick makes image manipulation in PHP extremely easy through an OO interface. Here is a quick example on how to make a thumbnail:

Using SPL and other OO features supported in Imagick, it can be simple to resize all files in a directory (useful for batch resizing large digital camera images to be web viewable). Here we use resize, as we might want to retain certain meta-data:

Example #2 Make a thumbnail of all JPG files in a directory

<?php

$images = new Imagick(glob('images
$im = new Imagick("test.png");


$im->thumbnailImage(200, null);


$im->borderImage(new ImagickPixel("white"), 5, 5);


$reflection = $im->clone();
$reflection->flipImage();


$gradient = new Imagick();


$gradient->newPseudoImage($reflection->getImageWidth() + 10, $reflection->getImageHeight() + 10, "gradient:transparent-black");


$reflection->compositeImage($gradient, imagick::COMPOSITE_OVER, 0, 0);


$reflection->setImageOpacity( 0.3 );


$canvas = new Imagick();


$width = $im->getImageWidth() + 40;
$height = ($im->getImageHeight() * 2) + 30;
$canvas->newImage($width, $height, new ImagickPixel("black"));
$canvas->setImageFormat("png");


$canvas->compositeImage($im, imagick::COMPOSITE_OVER, 20, 10);
$canvas->compositeImage($reflection, imagick::COMPOSITE_OVER, 20, $im->getImageHeight() + 10);


header("Content-Type: image/png");
echo $canvas;
?>

The above example will output something similar to:

This example illustrates how to use fill patterns during drawing.

Example #4 Filling text with gradient

<?php


$im = new Imagick();


$im->newPseudoImage(50, 50, "gradient:red-black");


$draw = new ImagickDraw();


$draw->pushPattern('gradient', 0, 0, 50, 50);


$draw->composite(Imagick::COMPOSITE_OVER, 0, 0, 50, 50, $im);


$draw->popPattern();


$draw->setFillPatternURL('#gradient');


$draw->setFontSize(52);


$draw->annotation(20, 50, "Hello World!");


$canvas = new Imagick();
$canvas->newImage(350, 70, "white");


$canvas->drawImage($draw);


$canvas->borderImage('black', 1, 1);


$canvas->setImageFormat('png');


header("Content-Type: image/png");
echo $canvas;
?>

The above example will output something similar to:

Working with animated GIF images

Working with ellipse primitive and custom fonts

Example #6 Create a PHP logo

<?php

$width = 400;
$height = 210;


$img = new Imagick();
$img->newImage($width, $height, new ImagickPixel('transparent'));


$draw = new ImagickDraw();

$draw->setFillColor('#777bb4');

$draw->ellipse($width / 2, $height / 2, $width / 2, $height / 2, 0, 360);

$img->drawImage($draw);


$draw->setFillColor('black');

$draw->setStrokeColor('white');

$draw->setStrokeWidth(2);

$draw->setTextKerning(-8);

$draw->setFont('Handel Gothic.ttf');
$draw->setFontSize(150);

$draw->setGravity(Imagick::GRAVITY_CENTER);


$img->annotateImage($draw, 0, -10, 0, 'php');
$img->setImageFormat('png');


header('Content-Type: image/png');
echo $img;
?>

The above example will output something similar to:
