PHP, Structures and Functions, IMAGICK


<?php



bool public Imagick::thumbnailImage(

       int $columns,

       int $rows,

    bool $bestfit = false,

    bool $fill = false,

    bool $legacy = false

);



?>

$columns

As Image width.

$rows

As Image height.

$bestfit

To force maximum values.

If true then columns and rows parameters are used as maximums for each side.
Both sides will be scaled down until they match or are smaller than the parameter given for the side.
If is used both width and height must be given.

$legacy

true or false.

$fill

true or false.

This function returns a TRUE on success.

Changes the size of an image to the given dimensions and removes any associated profiles.

The goal is to produce small, low cost thumbnail images suited for display on the Web.

Before Imagick 3.0.0 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.
