ImageSize

Zend\Validator\File\ImageSize checks the size of image files. Minimum and/or maximum dimensions can be set to validate against.

Supported Options

The following set of options are supported:

• minWidth (int|null) default: null

• minHeight (int|null) default: null

• maxWidth (int|null) default: null

• maxHeight (int|null) default: null

  To bypass validation of a particular dimension, the relevant option should be set to null.

Usage Examples

// Is image size between 320x200 (min) and 640x480 (max)?
$validator = new \Zend\Validator\File\ImageSize(320, 200, 640, 480);

// ...or with array notation
$validator = new \Zend\Validator\File\ImageSize(array(
    'minWidth' => 320, 'minHeight' => 200,
    'maxWidth' => 640, 'maxHeight' => 480,
));

// Is image size equal to or larger than 320x200?
$validator = new \Zend\Validator\File\ImageSize(array(
    'minWidth' => 320, 'minHeight' => 200,
));

// Is image size equal to or smaller than 640x480?
$validator = new \Zend\Validator\File\ImageSize(array(
    'maxWidth' => 640, 'maxHeight' => 480,
));

// Perform validation with file path
if ($validator->isValid('./myfile.jpg')) {
    // file is valid
}
