WP_REST_Attachments_Controller::get_special_image_sizes │ private static │ WP 7.1.0

Returns the image size names which name a single file rather than a sub-size.

Each of these is handled on its own in {@see self::sideload_item()} and stored under its own key by {@see self::finalize_item()}, so unlike a regular sub-size none of them may appear in an array of names sharing one file.

Method of the class: WP_REST_Attachments_Controller{}

No Hooks.

Returns

string[]. Special image size names.

Usage

$result = WP_REST_Attachments_Controller::get_special_image_sizes(): array;
