Imagick::scaleImage — Scales the size of an image

说明

bool Imagick::scaleImage ( int $cols , int $rows [, bool $bestfit = false ] )

Warning

本函数还未编写文档，仅有参数列表。

Scales the size of an image to the given dimensions. The other parameter will be calculated if 0 is passed as either param.

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.

参数

cols
rows
bestfit

返回值

Returns TRUE on success.

错误/异常

Throws ImagickException on error.
