# Imagick::distortImage

(PECL imagick 2.0.1)

Imagick::distortImage — Distorts an image using various distortion methods

### Descrição

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

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.

This method is available if Imagick has been compiled against ImageMagick version 6.3.6 or newer.

### Parâmetros

`method`

  The method of image distortion. See distortion constants

`arguments`

  The arguments for this distortion method

`bestfit`

  Attempt to resize destination to fit distorted source

### Valor Retornado

Retorna `TRUE` em sucesso.

### Erros

Dispara ImagickException em erro.

### Exemplos

Exemplo #1 Using Imagick::distortImage():

Distort an image and display to the browser.

`<?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);
/* Ouput the image */
header("Content-Type: image/png");
echo $im;
?>`
