aiuto nel salvare una variabile

[sharky86]

ciao a tutti!

ho trovato questo script su internet ma il codice é troppo complicato per me. cio che vorrei fare é la cosa seguente...

nel codice guardate il pezzo finale dopo il blocco commentato.

li viene generato un testo e scritto all interno dell immagine. cio che vorrei fare é salvare questo testo in una variabile. come si fa? grazie

(questa parte di codice verrebbe eseguita piu volte, una per ogni dato salvato. il dato salvato é soltanto uno nel mio caso percio non mi importa se la variabile viene sovvrascritta)
