Cet article présente un exemple qui illustre l’utilisation de marqueurs d’image lors du regroupement de données dans des marqueurs intelligents.
Utilisation de marqueurs d’image lors du regroupement de données dans des marqueurs intelligents
L’exemple de code suivant crée un classeur, puis ajoute les balises de marqueur intelligent suivantes dans les cellules D2, E2 et F2 respectivement.
&=Person.Name(group:normal,skip:1)
&=Person.City
&=Person.Photo(Picture:FitToCell)
Ensuite, il remplit la source de données avec des données et appelle leWorkbookDesigner.Process() pour traiter les marqueurs intelligents. Le code utilise ces images, c’est-à-direlune.png etlune2.png mais vous pouvez utiliser n’importe quelle image. La capture d’écran suivante montre la sortie de cet exemple de code. Comme vous pouvez le voir, les données des colonnes E et F sont regroupées par rapport aux données de la colonne D.
