Scales an image


Imagick::resizeImage

(PECL imagick 2.0.0)

Imagick::resizeImageScales an image

Description

bool Imagick::resizeImage ( int $columns , int $rows , int $filter , float $blur [, bool $bestfit = false ] )

Scales an image to the desired dimensions with a filter.

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

Width of the image

rows

Height of the image

filter

Refer to the list of filter constants.

blur

The blur factor where > 1 is blurry, < 1 is sharp.

bestfit

Optional fit parameter.

Return Values

Returns TRUE on success.

Changelog

Version Description
2.1.0 Added optional fit parameter. This method now supports proportional scaling. Pass zero as either parameter for proportional scaling.
