Returns an array containing a reconstructed image and the difference between images.

Composite one image onto another at the specified offset.

$imagick = new Imagick($input);
$imagick->blurImage(0,.5);
$overlay = new Imagick($image);
$imagick->compositeImage($overlay, imagick::COMPOSITE_SOFTLIGHT, 0, 0);
$imagick->writeImage("compositeImage.jpg");

( Softlight effect )

Creates an Imagick instance for a specified image or set of images.

Enhances the intensity differences between the lighter and darker elements of the image.

$im = new Imagick($input);
$im->contrastImage(5);
$im->writeImage( 'contrastImage.jpg' );
$im->destroy();

( Set sharpen to a value other than 0 to increase the image contrast otherwise the contrast is reduced. )

Enhances the contrast of a color image by adjusting the pixels color to span the entire range of colors available.

$im = new Imagick($input);
$im->contrastStretchImage(.15, .05);
$im->writeImage('contrastStretchImage.jpg'); 
$im->destroy();

Applies a custom convolution kernel to the image.

$image = new imagick( "input.jpg" ); 
$edgeArray = array(-1,-1,-1,-1,8,-1,-1,-1,-1);
$image->convolveImage ($edgeArray);
$image->thresholdImage(1);
$image->writeImage('convolveImage.jpg'); 
$image->destroy();

Extracts a region of the image.

$im = new Imagick($input);
$im->cropImage( 100, 100, 60, 20 );
$im->writeImage('cropImage.jpg'); 
$im->destroy();

Creates a fixed size thumbnail by first scaling the image up or down and cropping a specified area from the center.

$im = new Imagick($input);
$im->cropThumbnailImage( 150, 150 );
$im->writeImage('cropThumbnailImage.jpg'); 
$im->destroy();

Returns reference to the current imagick object with image pointer at the correct sequence.

Displaces an image's colormap by a given number of positions.

$im = new Imagick($input);
$im->cycleColormapImage(80);
$im->writeImage('cycleColormapImage.jpg'); 
$im->destroy();

( If you do this a few times, it produces a psychedelic effect. )

Deciphers image that has been enciphered before.

$im = new Imagick('encipherImage.png');
$im->decipherImage(passkey.txt);
$im->writeImage('decipherImage.png'); 
$im->destroy();

( The image must be enciphered using encipherImage(). )

Compares each image with the next in a sequence and returns the maximum bounding region of any pixel differences it discovers.

$im = new Imagick();
$im->readImage('addNoiseImage.jpg');
$im->readImage('adaptiveBlurImage.jpg');
$deconstruct = $im->deconstructImages ();
$deconstruct->writeImage('deconstructImages.jpg'); 
$deconstruct->destroy();

( 'Not working' )

Deletes an artifact associated with the image.

( The difference between image properties and image artifacts is that properties are public and artifacts are private. )

This method can be used to remove skew from for example scanned images where the paper was not properly placed on the scanning surface.

$im = new Imagick('text.png');
$im->deskewImage( 80 );
$im->writeImage( 'deskew.jpg' );
$im->destroy();
