Imagick::resizeImage — Scales an image

说明

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

Warning

本函数还未编写文档，仅有参数列表。

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.

参数

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.

返回值

Returns TRUE on success.

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