Class Reference/WP Image Editor



WP_Image_Editor is a class defined in wp-includes/class-wp-image-editor.php that is an abstract class, so it can't be called directly. It is used for implementations like WP_Image_Editor_GD and WP_Image_Editor_Imagick. It has some base functionality that can be used by those implementations.

Interacting with WP_Image_Editor


$image = wp_get_image_editor( 'cool_image.jpg' ); // Return an implementation that extends <tt>WP_Image_Editor</tt>

if ( ! is_wp_error( $image ) ) {
    $image->rotate( 90 );
    $image->resize( 300, 300, true );
    $image->save( 'new_image.jpg' );

Methods and Properties

You shouldn't call an implementation directly. Instead, use wp_get_image_editor(), which looks at which implementation is the best.


(An ampersand (&) before a method name indicates it returns by reference.)
