(PECL imagick 2.0.1)
Imagick::distortImage — Distorts an image using various distortion methods
$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.
Ta metoda jest dostępna, jeśli rozszerzenie Imagick zostało skompilowane z ImageMagick w wersji 6.3.6 lub nowszej.

Przykład #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;
?>
