File

./imageapi.module, line 160

An ImageAPI supporting additional image plugins as modules. Images are treated as objects, and images are not written per manipulation as Drupal's core image handling works.

Code

function imageapi_toolkit_invoke($method, &$image, array $params = array()) {
  $function = $image->toolkit . '_image_' . $method;
  if (function_exists($function)) {
    array_unshift($params, $image);
    $params[0] =& $image;
    return call_user_func_array($function, $params);
  }
  watchdog('imageapi', 'The selected image handling toolkit %toolkit can not correctly process %function.', array(
    '%toolkit' => $image->toolkit,
    '%function' => $function,
  ), WATCHDOG_ERROR);
  return FALSE;
