I am Using Itext 5 maven and I want to add multiple textfields in multiple pdf pages. like page 1 need 3 fields, page 2 need 4 fields etc.
I have write the below code
public byte[] setupDocument(EditPdfDTO editPdfDTOList, MultipartFile attachment)
{
WritePDF obj = new WritePDF();
Document document = null;
PdfWriter writer = null;
PdfImportedPage page = null;
PdfReader reader = null;
try
{
// Create output PDF
document = new Document(PageSize.A4);
document.setMargins(0, 0, 0, 0);
writer = PdfWriter.getInstance(document,
new FileOutputStream("D:/test.pdf"));
document.open();
PdfContentByte cb = writer.getDirectContent();
// Load existing PDF
reader = new PdfReader(attachment.getBytes());
int totalPages = reader.getNumberOfPages();
for (int i = 0; i < totalPages; i++)
{
page = writer.getImportedPage(reader, i + 1);
document.newPage();
cb.addTemplate(page, 0, 0);
for (int j = 0; j < editPdfDTOList.getPdf().size(); j++)
{
if (i + 1 == editPdfDTOList.getPdf().get(j).getPageNo())
{
BaseFont baseFont = null;
try
{
baseFont = BaseFont.createFont();
}
catch (DocumentException | IOException e1)
{
e1.printStackTrace();
}
int a, b;
a = editPdfDTOList.getPdf().get(j).getxCoordinate();
b = editPdfDTOList.getPdf().get(j).getyCoordinate();
String str = editPdfDTOList.getPdf().get(j).getTextContent();
Rectangle linkLocation =
new Rectangle(a, b + baseFont.getDescentPoint(str, 10),
a + 10 + baseFont.getWidthPoint(str, 10),
b + baseFont.getAscentPoint(str, 10) + 10);
TextField field =
new TextField(writer, linkLocation, "user1" + j+UUID.randomUUID());
field.setFontSize(10);
field.setOptions(TextField.MULTILINE | TextField.READ_ONLY);
field.setTextColor(BaseColor.RED);
field.setText(str);
field.setBorderWidth(1);
cb = writer.getDirectContent();
try
{
cb.addAnnotation(field.getTextField(),false);
}
catch (IOException | DocumentException e)
{
e.printStackTrace();
}
}
}
}
}
catch (DocumentException | IOException e)
{
e.printStackTrace();
}
catch (Exception e)
{
e.printStackTrace();
}
finally
{
document.close();
}
return null;
}
this code is able to add only one Textfield on every expected but not to add 2 or many textfields in a single page.
there is no issue of multiple try--catch block.
