Imagick::thumbnailImage — Changes the size of an image
$columns
, int $rows
[, bool $bestfit
= FALSE
[, bool $fill
= FALSE
[, bool $legacy
= FALSE
]]] ) : bool
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
they 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,当目标尺寸设为 400x400 时,原尺寸为 200x150 的图像将不会被改变。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。
