Använda bildmarkörer samtidigt som data grupperas i smarta markörer

Den här artikeln presenterar ett exempel som illustrerar användningen av bildmarkörer medan data grupperas i smarta markörer.

Använda bildmarkörer samtidigt som data grupperas i smarta markörer

Följande exempelkod skapar en arbetsbok och lägger sedan till följande smarta markörtaggar i cellerna D2, E2 respektive F2.

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

&=Person.City

&=Person.Photo(Picture:FitToCell)

Sedan fyller den datakällan med data och anroparWorkbookDesigner.Process() metod för att bearbeta smarta markörtaggar. Koden använder dessa bilder dvsmoon.png ochmoon2.png men du kan använda vilken bild som helst. Följande skärmdump visar utdata från denna exempelkod. Som du kan se är data i kolumn E och F grupperade med avseende på data i kolumn D.

public static void main(String[] args) throws Exception {

	 // The path to the documents directory.
	String dataDir = Utils.getDataDir(SmartMarkerGroupingImage.class);
	
	SmartMarkerGroupingImage grouping = new SmartMarkerGroupingImage();
	grouping.Execute(dataDir);
}

public void Execute(String dataDir) throws Exception {

	//Get the image
	Path path = Paths.get(dataDir + "sample1.png");
	byte[] photo1 = Files.readAllBytes(path);
	
	//Get the image
	path = Paths.get(dataDir + "sample2.jpg");
	byte[] photo2 = Files.readAllBytes(path);
	
	//Create a new workbook and access its worksheet
	Workbook workbook = new Workbook();
	Worksheet worksheet = workbook.getWorksheets().get(0);

	//Set the standard row height to 35
	worksheet.getCells().setStandardHeight(35);

	//Set column widhts of D, E and F
	worksheet.getCells().setColumnWidth(3, 20);
	worksheet.getCells().setColumnWidth(4, 20);
	worksheet.getCells().setColumnWidth(5, 40);

	//Add the headings in columns D, E and F
	worksheet.getCells().get("D1").putValue("Name");
	Style st = worksheet.getCells().get("D1").getStyle();
	st.getFont().setBold(true);
	worksheet.getCells().get("D1").setStyle(st);

	worksheet.getCells().get("E1").putValue("City");
	worksheet.getCells().get("E1").setStyle(st);

	worksheet.getCells().get("F1").putValue("Photo");
	worksheet.getCells().get("F1").setStyle(st);

	//Add smart marker tags in columns D, E, F
	worksheet.getCells().get("D2").putValue("&=Person.Name(group:normal,skip:1)");
	worksheet.getCells().get("E2").putValue("&=Person.City");
	worksheet.getCells().get("F2").putValue("&=Person.Photo(Picture:FitToCell)");

	//Create Persons objects with photos
	ArrayList<Person> persons = new ArrayList<Person>();       
	persons.add(new Person("George", "New York", photo1));
	persons.add(new Person("George", "New York", photo2));
	persons.add(new Person("George", "New York", photo1));
	persons.add(new Person("George", "New York", photo2));
	persons.add(new Person("Johnson", "London", photo2));
	persons.add(new Person("Johnson", "London", photo1));
	persons.add(new Person("Johnson", "London", photo2));
	persons.add(new Person("Simon", "Paris", photo1));
	persons.add(new Person("Simon", "Paris", photo2));
	persons.add(new Person("Simon", "Paris", photo1));
	persons.add(new Person("Henry", "Sydney", photo2));
	persons.add(new Person("Henry", "Sydney", photo1));
	persons.add(new Person("Henry", "Sydney", photo2));
	
	//Create a workbook designer
	WorkbookDesigner designer = new WorkbookDesigner(workbook);

	//Set the data source and process smart marker tags
	designer.setDataSource("Person", persons);
	designer.process();

	//Save the workbook
	workbook.save(dataDir + "output.xlsx", SaveFormat.XLSX);
	
	System.out.println("File saved");
