Hello,
I have been working with IText for 2 weeks now and already read through 3
quaters of the book which I have bought last week. Its really interesting how
many different options I got in manipulating pdf and generate new ones.
But as usuall there are questions coming up which are not quite easily to be
answered by the given examples or tutorials, of which I have read almost all =)
Problem:
I have a "Pdf Template" called ExportTemplate.pdf, having 3 PdfFormFields to be
filled in, which works perfectly using the pdf stamper.
But now i want to add a PdfPTable using Columntext to illustrated a large Table
that should start directly beyond these 3 form fields.
my steps:
1. read the template (template = new
RandomAccessFileOrArray("ExportTemplate.pdf") to memory
2. fill fields with stamper
3. read stamped pdf from memory ==> reader = new PdfReader(baos.toByteArray())
4. creating a copy of the memory page + importing the first page which i have
already filled in
5.ADD TABLE WITH DYNAMIC CONTENT:
The result i get is that i get only the copy of my first page but no table is
added.
I expected the table to be added in the middle of the page. The y-coordinates
for the simpleColumn have just been set to the middle to see whether something
has been added at least.
I am going to give you the code below to illustrate what i have already done.
PdfReader reader;
ByteArrayOutputStream baos;
PdfStamper stamper;
AcroFields field;
PdfContentByte cb;
ColumnText ct;
Color textColor = Color.lightGray;
RandomAccessFileOrArray template;
Document document = new Document();
try
{
template = new
RandomAccessFileOrArray("ExportTemplate.pdf");
reader = new PdfReader(template, null);
baos = new ByteArrayOutputStream();
stamper = new PdfStamper(reader, baos);
//fill fields
field = stamper.getAcroFields();
field.setFieldProperty(identitaet, "textsize", 10f,
null);
field.setField(identitaet, idBeteiligungshalter);
field.setFieldProperty(name, "textsize", 10f, null);
field.setField(name, nameBeteiligungshalter);
field.setFieldProperty(date, "textsize", 10f, null);
field.setField(date, stichtag);
stamper.setFormFlattening(true);
stamper.close();
reader = new PdfReader(baos.toByteArray());
document = new
Document(reader.getPageSizeWithRotation(1));
PdfCopy copy = new PdfCopy(document, new
FileOutputStream("FilledExportTemplate.pdf"));
document.open();
copy.addPage(copy.getImportedPage(reader, 1));
cb = copy.getDirectContent();
ct = new ColumnText(cb);
ct.setAlignment(Element.ALIGN_CENTER);
ct.setSimpleColumn(36, 36, document.right() - 36,
document.top() - 36);
//generate table body
PdfPTable tableMainHeader = new PdfPTable(7);
tableMainHeader.setWidthPercentage(100f);
tableMainHeader.setWidths(new int[] { 15, 35, 10, 10,
10, 10, 10 });
PdfPCell cell = new PdfPCell();
for (int m = 0; m < beteiligungen.size(); m++)
//beteiligungen size =660 table rows each having 7 columns
{
for (int l = 0; l < 7; l++)
{
cell = new PdfPCell();
cell.setBackgroundColor(textColor);
cell.setMinimumHeight(30f);
cell.addElement(new
Chunk(beteiligungEigenschaften[m][l].toString()));
tableMainHeader.addCell(cell);
}
}
ct.addElement(tableMainHeader);
//render
int currentColumn =0;
while (true)
{
int status = ct.go();
if ((status & ColumnText.NO_MORE_TEXT) != 0)
{
System.out.println(status);
System.out.println(ColumnText.NO_MORE_COLUMN);
System.out.println(ColumnText.NO_MORE_TEXT);
break;
}
++currentColumn;
if(currentColumn>=1){
break;
}
}
}
catch (DocumentException de)
{
System.err.println(de.getMessage());
}
catch (IOException ioe)
{
System.err.println(ioe.getMessage());
}
document.close();
I hope there is an obvious fault in my code that might be found easily.
Looking forward to your reply
regards
Stephan
