Imagick::thumbnailImage

(PECL imagick 2.0.0)

Imagick::thumbnailImage — Changes the size of an image

说明

bool Imagick::thumbnailImage ( int $columns , int $rows [, bool $bestfit = false [, bool $fill = false ]] )

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. If TRUE is given as a third parameter then columns and rows parameters are used as maximums for each side. Both sides will be scaled down until the match or are smaller than the parameter given for the side.

Note: 参数bestfit的特性在 Imagick 3.0.0 中已改变. 在此版本以前, 当目标尺寸为400x400,尺寸为200x150的源图像将不会被改变. 自 Imagick 3.0.0 起, 源图像将会被放大到 400x300 因为这将更好的适合目标尺寸. 当使用参数 bestfit 时,必须同时给出宽度和高度

参数

columns: Image width
rows: Image height
bestfit: Whether to force maximum values
