How to scroll a pic

how to scroll a pic on a area like below pic

learning the image-widget (lv_img) at
https://docs.littlevgl.com/en/html/object-types/img.html

and then change y-position of the lv_img by
lv_obj_set_y(...)

https://docs.littlevgl.com/en/html/object-types/obj.html#_CPPv412lv_obj_set_yP8lv_obj_t10lv_coord_t

Unfortunately, though, the image object doesn’t support wrapping an image around like this. So you would just get blank space above and below the real image.

thanks for your respond. actually I need the icon loop wrapping on a area

thx for respond. my confuse is how to define an area, and the icon loop this area

It’s not supported by LittlevGL right now - the feature would have to be added by someone.
