Imagemagick Functions

Imagick::adaptiveResizeImage

Description:

bool Imagick::adaptiveResizeImage ( int $width , int $height [, bool $fit ] )

Adaptively resize image with data-dependent triangulation. Avoids blurring across sharp color changes. Most useful when used to shrink images slightly to a slightly smaller "web size"; may not look good when a full-sized image is adaptively resized to a thumbnail.

Parameters

width: Width of scaled image
height: Height of scaled image
fit: Optional fit parameter. If absent or FALSE, pass zero as either width or height for proportional scaling.

Return Values

Returns TRUE on success.

Errors/Exceptions

Throws ImagickException on error.

Example


<?php 
$image = new Imagick("opossum.jpg"); 

$resize = .7;
$w = $image->getImageWidth();

$image->adaptiveResizeImage( $resize*$w, 0, FALSE ); 

header( "Content-Type: image/jpeg" );
echo $image;
?>
