public ImageToolkitInterface::getMimeType() Returns the MIME type of the image file. Return value string The MIME type of the image file, or an empty string if the image is invalid.

public ImageToolkitInterface::apply($operation, array $arguments = array()) Applies a toolkit operation to an image. Parameters string $operation: The toolkit operation to be processed. array $arguments: An associative array of arguments to be passed to the toolkit operation, e.g. array('width' => 50, 'height' => 100, 'upscale' => TRUE).
