resize — Resize current image
Description
public Intervention\Image\Image resize (integer $width, integer $height, [Closure $callback])
Resizes current image based on given width and/or height. To constraint the resize command, pass an optional Closure callback as third parameter.
Parameters
width
The new width of the image
height
The new height of the image
callback (optional)
Closure callback defining constraints on the resize. It’s possible to constraint the aspect-ratio and/or a unwanted upsizing of the image. See examples below.
aspectRatio
public Intervention\Image\Size aspectRatio()
Constraint the current aspect-ratio of the image. As a shortcut to proportional resizing you can use widen() or heighten().
upsize
public Intervention\Image\Size upsize()
Keep image from being upsized.
Return Values
Instance of Intervention\Image\Image
Examples
// create instance
$img = Image::make('public/foo.jpg');
// resize image to fixed size
$img->resize(300, 200);
// resize only the width of the image
$img->resize(300, null);
// resize only the height of the image
$img->resize(null, 200);
// resize the image to a width of 300 and constrain aspect ratio (auto height)
$img->resize(300, null, function ($constraint) {
$constraint->aspectRatio();
});
// resize the image to a height of 200 and constrain aspect ratio (auto width)
$img->resize(null, 200, function ($constraint) {
$constraint->aspectRatio();
});
// prevent possible upsizing
$img->resize(null, 400, function ($constraint) {
$constraint->aspectRatio();
$constraint->upsize();
});
// resize the image so that the largest side fits within the limit; the smaller
// side will be scaled to maintain the original aspect ratio
$img->resize(400, 400, function ($constraint) {
$constraint->aspectRatio();
$constraint->upsize();
});
