Imagick::adaptiveResizeImage
Adaptively resize image with data dependent triangulation
Description
public bool Imagick::adaptiveResizeImage(
int $columns
,
int $rows
,
bool $bestfit
= false
,
bool $legacy
= false
)
Note:
The behavior of the parameter bestfit
changed in Imagick 3.0.0.
Before this version given dimensions 400x400 an image of dimensions 200x150 would be
left untouched. In Imagick 3.0.0 and later the image would be scaled up to size 400x300 as
this is the "best fit" for the given dimensions. If bestfit
parameter is used both width and height must be given.
Parameters
-
columns
-
The number of columns in the scaled image.
-
rows
-
The number of rows in the scaled image.
-
bestfit
-
Whether to fit the image inside a bounding box.
Return Values

on success.
Errors/Exceptions
Throws ImagickException on error.
Examples
Example #1 Using Imagick::adaptiveResizeImage
Resize an image to a standard size for the web. This method works best
when resizing to a size only slightly smaller than the previous image
size.
<?php
header('Content-type: image/jpeg');
$image = new Imagick('image.jpg');
$image->adaptiveResizeImage(1024,768);
echo $image;
?>
