Let me paste the method I am using to create the pdf. I obtain the
signatureString from the database and it contains the text of the
letter. There's no special formatting, just straight text. Here's the
method:
public void doPrint(OutputStream bos) {
String printString = signatureText;
Font font = FontFactory.getFont(FontFactory.HELVETICA, 10);
Document document = new Document(PageSize.LETTER, 60, 80, 157,
90);
try {
PdfWriter.getInstance(document, bos);
document.open();
int i;
int lineLen;
String line;
Phrase ph = new Phrase();
ph.setLeading(12f);
BufferedReader in = new BufferedReader(new
StringReader(printString));
while ((line = in.readLine()) != null) {
line = line.trim();
lineLen = line.length();
i = 0;
StringBuffer parsedBuf = new StringBuffer();
while (i < lineLen) {
// Make sure there is enough room for the
DELIMITER+SKIPMARKER+(DELIMITER or New Line)
if ((i < lineLen - 2) &&
(line.charAt(i) == Parser.DELIMITER &&
line.charAt(i + 1) == Parser.SKIP_MARKER)) {
i += 2;
// Advance past the DELIMITER and SKIPMARKER
StringBuffer attribute = new StringBuffer();
while (i < lineLen) {
// Break at next DELIMITER or New Line
if ((line.charAt(i) == Parser.DELIMITER) ||
(line.charAt(i) == '\n')) {
System.out.println("Found Attribute: " +
attribute.toString());
break;
}
attribute.append(line.charAt(i));
i++;
}
// Try to take action on the attribute
if (attribute.toString().compareTo("SignatureImage") == 0)
{
try {
Image img = (Image)
signatureImages.get(signatureId.trim());
if (img == null) {
URL imageUrl = new URL("http", host, port,
sigImageDir + signatureId.trim() + sigImageSuffix);
img = Image.getInstance(imageUrl);
img.scalePercent(10);
signatureImages.put(signatureId.trim(), img);
}
ph = new Phrase(new Chunk(img, 0, -45));
ph.setLeading(12f);
document.add(ph);
parsedBuf = null;
}
catch (FileNotFoundException fnf){
System.out.println("Image " + signatureId + " not found
in " + sigImageDir);
}
catch (Exception e) {
e.printStackTrace();
// Add returns to line if image was not inserted
parsedBuf.append("\n\n\n");
}
}
else if (attribute.toString().compareTo("SignatureName") ==
0) {
parsedBuf.append(signatureName);
}
else if
(attribute.toString().compareTo("SignatureInitials") == 0) {
parsedBuf.append(signatureInitials);
}
else if (attribute.toString().compareTo("PageBreak") == 0)
{
document.newPage();
}
else if (attribute.toString().compareTo("DeskCodeFax") ==
0){
parsedBuf.append(deskCodeFax);
}
else {
try {
System.out.println("Found attribute that requires a
method not able to be handled in this class: " +
attribute.toString());
}
catch (Exception ex) {
ex.printStackTrace();
}
}
}
else {
parsedBuf.append(line.charAt(i));
}
i++;
}
if (parsedBuf != null) {
line = parsedBuf.toString();
ph = new Phrase(line + "\n", font);
ph.setLeading(12f);
document.add(ph);
}
else {
ph = new Phrase("\n\n\n\n");
ph.setLeading(12f);
document.add(ph);
}
}
}
catch (NullPointerException ne) {
System.err.println(ne.getMessage());
System.out.println("NullPointerException occurred in
PDFiText....");
}
catch (DocumentException de) {
System.err.println(de.getMessage());
}
catch (IOException ioe) {
System.err.println(ioe.getMessage());
}
document.close();
}
Since I'm using the Document and PdfWriter.getInstance(), in order to
use ColumnText, I'm going to have to redesign the page using:
PdfWriter writer = PdfWriter.getInstance(document, bos);
PdfContentByte cb = writer.getDirectContent();
ColumnText ct = new ColumnText(cb);
Then I'll do everything with cb and ct tho I don't really care about
absolute positioning of the text since I'll add text as I read it in the
position it was last written. If I have to use this is there a way to
just showText() without setting the alignment or positioning? If I do
have to supply the positioning, then my guess is top-most left-most part
of the page is (0,0)? Then I'll have to take in account the margins and
the full text width of a line minus the margin size. This could get
ugly:-) I guess what I'm getting at - there is no
Document.getLineNumber()?
Thanks,
Patrick

You must use ColumnText for that kind of control.
