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:

Example #1 Creating a thumbnail in Imagick

<?php

header
('Content-type: image/jpeg');

$image = new Imagick('image.jpg');

// If 0 is provided as a width or height parameter,
// aspect ratio is maintained
$image->thumbnailImage(1000);

echo 
$image;

?>

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/*.JPG'));

foreach(
$images as $image) {

    
// Providing 0 forces thumbnailImage to maintain aspect ratio
    
$image->thumbnailImage(1024,0);

}

$images->writeImages();

?>

This is an example of creating a reflection of an image. The reflection is created by flipping the image and overlaying a gradient on it. Then both, the original image and the reflection is overlayed on a canvas.

Example #3 Creating a reflection of an image

<?php
/* Read the image */
$im = new Imagick("test.png");

/* Thumbnail the image */
$im->thumbnailImage(200null);

/* Create a border for the image */
$im->borderImage(new ImagickPixel("white"), 55);

/* Clone the image and flip it */
$reflection $im->clone();
$reflection->flipImage();

/* Create gradient. It will be overlayed on the reflection */
$gradient = new Imagick();

/* Gradient needs to be large enough for the image and the borders */
$gradient->newPseudoImage($reflection->getImageWidth() + 10$reflection->getImageHeight() + 10"gradient:transparent-black");

/* Composite the gradient on the reflection */
$reflection->compositeImage($gradientimagick::COMPOSITE_OVER00);

/* Add some opacity. Requires ImageMagick 6.2.9 or later */
$reflection->setImageOpacity0.3 );

/* Create an empty canvas */
$canvas = new Imagick();

/* Canvas needs to be large enough to hold the both images */
$width $im->getImageWidth() + 40;
$height = ($im->getImageHeight() * 2) + 30;
$canvas->newImage($width$height, new ImagickPixel("black"));
$canvas->setImageFormat("png");

/* Composite the original image and the reflection on the canvas */
$canvas->compositeImage($imimagick::COMPOSITE_OVER2010);
$canvas->compositeImage($reflectionimagick::COMPOSITE_OVER20$im->getImageHeight() + 10);

/* Output the image*/
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

/* Create a new imagick object */
$im = new Imagick();

/* Create new image. This will be used as fill pattern */
$im->newPseudoImage(5050"gradient:red-black");

/* Create imagickdraw object */
$draw = new ImagickDraw();

/* Start a new pattern called "gradient" */
$draw->pushPattern('gradient'005050);

/* Composite the gradient on the pattern */
$draw->composite(Imagick::COMPOSITE_OVER005050$im);

/* Close the pattern */
$draw->popPattern();

/* Use the pattern called "gradient" as the fill */
$draw->setFillPatternURL('#gradient');

/* Set font size to 52 */
$draw->setFontSize(52);

/* Annotate some text */
$draw->annotation(2050"Hello World!");

/* Create a new canvas object and a white image */
$canvas = new Imagick();
$canvas->newImage(35070"white");

/* Draw the ImagickDraw on to the canvas */
$canvas->drawImage($draw);

/* 1px black border around the image */
$canvas->borderImage('black'11);

/* Set the format to PNG */
$canvas->setImageFormat('png');

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

The above example will output something similar to:

Output of example : Filling text with gradient

Working with animated GIF images

Example #5 Read in GIF image and resize all frames

<?php

/* Create a new imagick object and read in GIF */
$im = new Imagick("example.gif");

/* Resize all frames */
foreach ($im as $frame) {
    
/* 50x50 frames */
    
$frame->thumbnailImage(5050);

    
/* Set the virtual canvas to correct size */
    
$frame->setImagePage(505000);
}

/* Notice writeImages instead of writeImage */
$im->writeImages("example_small.gif"true);
?>
