Zoom

zoom

You can specify the amount you want to zoom in / out of a picture or a part of it.

Parameters

The parameter is given in a %, where 1000 is a 1:1 ratio, while the value bigger than 1000 means closing (zooming) in, the one smaller then 1000 is zooming out.

• min 1
• max 10000

Limitations

• This transformation does not have any limitations.

Dependencies

• gravity: if gravity is specified, than the zooming measures should be considered in relation to the center of the gravity field.

Examples

See the following examples about the possible ways of usage.

Keeping the original image’s width at 500 px while zooming at the face by 50%

w:500/g:face_z:500

use shardimage\shardimagephp\factories\Transformation;
$transformations = (new Transformation())->width(500)->group()->gFace()->zoom(500);

Keeping the original image’s width at 500 px while zooming at the face by 100%

w:500/g:face_z:1000

use shardimage\shardimagephp\factories\Transformation;
$transformations = (new Transformation())->width(500)->group()->gFace()->zoom(1000);

Keeping the original image’s width at 500 px while zooming at the face by 150%

w:500/g:face_z:1500

use shardimage\shardimagephp\factories\Transformation;
$transformations = (new Transformation())->width(500)->group()->gFace()->zoom(1500);
