I have been doing some experiments with ColumnText to see if some
iText element fits in the page. I'm witting 38 time the word "Hello"
and 5 times the word "World". If the last 5 words does not fit in the
page I want them in a new page. Here is what I did
Document doc = new Document();
try {
PdfWriter w = PdfWriter.getInstance(doc, new
FileOutputStream("/home/fsousa/test.pdf"));
doc.open();
ColumnText ct = new ColumnText(w.getDirectContent());
ct.setSimpleColumn(doc.left(), doc.bottom(), doc.right(), doc.top());
for (int i = 0; i < 38; ++i)
ct.addElement(new Phrase(i + ". Hello"));
int status = ct.go();
while (ColumnText.hasMoreText(status)) {
doc.newPage();
ct.setYLine(doc.top());
status = ct.go();
}
float y = ct.getYLine();
for (int i = 0; i < 5; ++i)
ct.addElement(new Phrase(i + ". World\n"));
status = ct.go(true);
if (ColumnText.hasMoreText(status))
ct.setText(null);
for (int i = 0; i < 5; ++i)
ct.addElement(new Phrase(i + ". World\n"));
if (ColumnText.hasMoreText(status)) {
doc.newPage();
ct.setYLine(doc.top());
} else
ct.setYLine(y);
ct.go();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (DocumentException e) {
e.printStackTrace();
}
doc.close();
It works but I have to call ct.setText(null) to clear the remaining
elements in ColumnText. I could use ct.addText() instead of
ct.addElement() and calling ct.clearChunks(). Is this the right thing
or is there a better way.
