Picture maybe in ropy art (7)

I believe the answer is:
portray
'picture' is the definition.
(portray can mean to picture or paint)
'in ropy art' is the wordplay.
'ropy art' anagrams to 'PORTRAY'.
Though, I am not sure how the anagram is indicated.
'maybe' acts as a link.
Can you help me to learn more?
(Other definitions for portray that I've seen before include "Show" , "Depict in art" , "Delineate" , "sketch" , "Depict, present" .)
