Utilizzo di marcatori immagine durante il raggruppamento di dati in marcatori intelligenti

Utilizzo di marcatori immagine durante il raggruppamento di dati in marcatori intelligenti

L’esempio seguente crea una cartella di lavoro e quindi aggiunge i seguenti tag smart marker rispettivamente nelle celle D2, E2 e F2.

 &=Person.Name(group:normal,skip:1)

&=Person.City

&=Person.Photo(Picture:FitToCell)

Quindi riempie l’origine dati con i dati e chiama il fileWorkbookDesigner.Process() metodo per elaborare i tag dei marcatori intelligenti. Il codice utilizza queste immagini, ad esluna.png eluna2.png ma puoi usare qualsiasi immagine.
