Imagick::distortImage

PHP function Edit on GitHub ✎

(PECL imagick 2 >= 2.0.1, PECL imagick 3)

Distorts an image using various distortion methods

Description

Imagick::distortImage(int $method, array $arguments, bool $bestfit): bool

Distorts an image using various distortion methods, by mapping color lookups of the source image to a new destination image usually of the same size as the source image, unless 'bestfit' is set to true.

If 'bestfit' is enabled, and distortion allows it, the destination image is adjusted to ensure the whole source 'image' will just fit within the final destination image, which will be sized and offset accordingly. Also in many cases the virtual offset of the source image will be taken into account in the mapping.

Parameters

method: The method of image distortion. See distortion constants

php

<?php
/* Create new object */
$im = new Imagick();

/* Create new checkerboard pattern */
$im->newPseudoImage(100, 100, "pattern:checkerboard");

/* Set the image format to png */
$im->setImageFormat('png');

/* Fill new visible areas with transparent */
$im->setImageVirtualPixelMethod(Imagick::VIRTUALPIXELMETHOD_TRANSPARENT);

/* Activate matte */
$im->setImageMatte(true);

/* Control points for the distortion */
$controlPoints = array( 10, 10, 
                        10, 5,

                        10, $im->getImageHeight() - 20,
                        10, $im->getImageHeight() - 5,

                        $im->getImageWidth() - 10, 10,
                        $im->getImageWidth() - 10, 20,

                        $im->getImageWidth() - 10, $im->getImageHeight() - 10,
                        $im->getImageWidth() - 10, $im->getImageHeight() - 30);

/* Perform the distortion */                       
$im->distortImage(Imagick::DISTORTION_PERSPECTIVE, $controlPoints, true);

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