Commit cb523121be391f179a1f84da21114b44936e0d11 broke legacy API, elm_image_resize_up/down were renamed to scale_up/down but no legacy compatibility functions were added.
No. elm_image_resize_up did not exist in 1.17.
See also T4343 for an actual problem with elm_image.
OK I checked again, they were never EAPI. But they are now in 1.18 legacy header so they need to get removed, same as sizing_eval in T4343
