function image_styles_admin_duplicate in ImageCache Actions 8

Same name and namespace in other branches

1. 7 image_styles_admin/image_styles_admin.inc \image_styles_admin_duplicate()

Duplicates an image style and saves it.

Parameters

array $style: An image style array.

string|null $new_style_name: The preferred name for the new style. If left empty, the new name will be based on the name of the style to duplicate. In both cases and when necessary, the new name will be made unique by adding some suffix to it.

string|null $new_style_label: The preferred label for the new style. If left empty, the new label will be based on the label of the style to duplicate. If that one is also empty, no label will be defined for the new style, so Drupal (>=7.23) will create one.

Return value

array An image style array with the newly created copy of the given style.
