Hi Paulo,
I am here with another question.
I have a fixed size form which is populated using pdfstamper. I use the
following code :
ColumnText text = new ColumnText(stamper.getOverContent(1));
text.addText(new Phrase(value, FontFactory.getFont
(FontFactory.COURIER, 12, Font.NORMAL)));
AcroFields.Item item = form.getFieldItem(field);
if (item != null)
{
int pageN = ((Integer)item.page.get(0)).intValue();
text.setCanvas(stamper.getOverContent(pageN));
float[] position = form.getFieldPositions(field);
text.setSimpleColumn(position[1], position[2], position[3],
position[4]);
text.setAlignment(Element.ALIGN_JUSTIFIED);
}
if ((text.go() & ColumnText.NO_MORE_TEXT) == 0)
overflowFields.put(name, text);
I want to display the remaining data at the end of the document, so I store it
in a map for later use.
Now at the end of the page, I have a map (overflowFields) with String as key
and the value could be either String or ColumnText.
public byte[] drawAppendix(Map appendixFields) throws DocumentException
{
if (overflowFields == null || overflowFields.size() == 0)
return null;
Document doc = new Document(reader.getPageSize(1));
ByteArrayOutputStream appendix = new ByteArrayOutputStream();
//PdfWriter tempWriter = PdfWriter.getInstance(doc, appendix);
Font headerFont = FontFactory.getFont(FontFactory.HELVETICA, 12,
Font.BOLD);
Font footerFont = FontFactory.getFont(FontFactory.HELVETICA, 10);
HeaderFooter header = new HeaderFooter(new Phrase("Appendix",
headerFont), false);
header.setBorder(Rectangle.BOX);
header.setAlignment(HeaderFooter.ALIGN_CENTER);
doc.setHeader(header);
HeaderFooter footer = new HeaderFooter(new Phrase("Appendix Page ",
footerFont), true);
footer.setBorder(Rectangle.NO_BORDER);
footer.setAlignment(HeaderFooter.ALIGN_CENTER);
doc.setFooter(footer);
doc.open();
// PdfContentByte cb = tempWriter.getDirectContent();
Iterator iter = new TreeSet(overflowFields.keySet()).iterator();
Table table = new Table(1);
table.setBorder(Rectangle.BOX);
table.setWidth(100);
table.setPadding(5);
while (iter.hasNext())
{
String key = ((String) iter.next()).trim();
String name = (String) appendixFields.get(key);
Object value = overflowFields.get(key);
Cell cell = new Cell();
Chunk chunk1 = new Chunk(name + "\n", FontFactory.getFont
(FontFactory.HELVETICA, 10, Font.BOLD));
cell.add(chunk1);
if (value instanceof ColumnText)
{
ColumnText text = (ColumnText) value;
// Here I want to add the remaining text to the table
}
else
{
Chunk chunk2 = new Chunk((String)value, FontFactory.getFont
(FontFactory.COURIER, 12));
cell.add(chunk2);
}
table.addCell(cell);
}
doc.add(table);
doc.close();
return appendix.toByteArray();
}
It works fine with strings. I could not figure out how to do it with
columntext. Now I want all the data to display here so I dont know how to set
the column size. and if the data doe not fit in one page, it should grow to
the next page.
Thank you so much.
Merlyn.
