Verwenden von Bild Markern beim Gruppieren von Daten in Smart Markern

Verwenden von Bildmarkern beim Gruppieren von Daten in Smart Markern

Der folgende Beispielscode erstellt eine Arbeitsmappe und fügt anschließend die folgenden Smart-Marker-Tags in die Zellen D2, E2 und F2 ein.

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

&=Person.City

&=Person.Photo(Picture:FitToCell)

Dann füllt es die Datenquelle mit Daten und ruft die WorkbookDesigner.Process()Methode auf, um die Smart-Marker-Tags zu verarbeiten. Der Code verwendet diese Bilder d.h moon.png und moon2.png aber Sie können jedes Bild verwenden. Der folgende Screenshot zeigt die Ausgabe dieses Beispiels. Wie Sie sehen können, sind die Daten in Spalte E und F in Bezug auf die Daten in Spalte D gruppiert.

todo:image_alt_text

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");
