Examples

Grid Case 1

Source code: uia.pdf.GridViewTest

// 1. load layouts for a document
GridViewFactory factory1 = GridViewFactory.fromXml("sample/grid/layout.xml");

// 2. new a pdf
PDFDoc pdf = new PDFDoc(FontUtils.traditional());

// 3. prepare header and footer
SimpleHeaderView header = new SimpleHeaderView(pdf, "UIA4J", 20);
SimpleFooterView footer = new SimpleFooterView(pdf, "UIA4J-0920", "2018-09-20", 11);

// 4. add data
GridView view = factory1.mainView(pdf, Paper.A4L.paddingLR(100, 100), "employee");
view.setHeaderView(header);
view.setFooterView(footer);
view.draw(SampleEmployee.create(), "Employee List", true);

// 5. draw header & footer
header.draw();
footer.draw();

// 6.save
pdf.save(new File("output/grid_case1.pdf"));

Output:

GridBag Case 1

Source code: uia.pdf.GridBagViewTest

// 1. load layouts for a document
GridBagFactory factory1 = GridBagFactory.fromXml("sample/gridbag/layout_header_footer.xml");
GridBagFactory factory2 = GridBagFactory.fromXml("sample/gridbag/layout.xml");

// 2. new a PDF
PDFDoc pdf = new PDFDoc(FontUtils.simplified());

// 3. header & footer
GridBagDescriptionView header = factory1.descView(pdf, "header");
GridBagDescriptionView footer = factory1.descView(pdf, "footer");

// 4 A4
GridBagView cv1 = factory2.mainView(pdf, Paper.A4.paddingTB(100, 100));
cv1.setHeaderView(header);
cv1.setFooterView(footer);
cv1.addPage(prepareData1(), "Inspection Report 1", false);
cv1.addPage(prepareData2());
cv1.addPage(prepareData3(), "Inspection Report 2", false);

// 5 A4L
GridBagView cv2 = factory2.mainView(pdf, Paper.A4L);
cv2.setHeaderView(header);
cv2.setFooterView(footer);
cv2.addPage(prepareData1(), "Inspection Report 3", false);
cv2.addPage(prepareData2());
cv2.addPage(prepareData3(), "Inspection Report 4", false);

// 6. draw header & footer
header.draw();
footer.draw();
