I've reached a solution and it works with this sample code:
public prova(String filePath) throws IOException, DocumentException{
Document document = new Document(PageSize.A4);
File f = new File("C:\\tempPDF_GDF.pdf");
FileOutputStream fileOutputStream = new FileOutputStream(f);
PdfWriter writer = PdfWriter.getInstance(document,
fileOutputStream);
writer.setPageCount(10);
writer.setBoxSize("page", new Rectangle(36, 54, 559, 788));
document.open();
PdfContentByte cb = writer.getDirectContent();
ColumnText ct = new ColumnText(cb);
ct.setSimpleColumn(36, 54, 559, 788);
Phrase p, p_r = new Phrase();
float counter = 36;
System.out.println("Y->"+ct.getYLine()+" - X->"+ct.getLastX());
p = new Phrase("TRIAL TEXT: ", new Font(FontFamily.TIMES_ROMAN,
14,
Font.NORMAL));
System.out.println("PhraseWidth->"+ct.getWidth(p));
counter+=ct.getWidth(p);
ct.addText(p);
System.out.println("Y->"+ct.getYLine()+" - X->"+ct.getLastX());
p = new Phrase("I use it just to prove if it starts a new line
in the
event that the text block overflows the line capacity ", new
Font(FontFamily.TIMES_ROMAN, 14, Font.NORMAL));
System.out.println("PhraseWidth->"+ct.getWidth(p));
ct.addText(p);
PdfLayer lay1 = new PdfLayer("entity_highlighting", writer);
cb.beginLayer(lay1);
LineSeparator lineSeparator = new LineSeparator();
lineSeparator.setLineColor(BaseColor.YELLOW);
lineSeparator.setLineWidth(14);
lineSeparator.drawLine(cb, counter, 559, 776);
lineSeparator.drawLine(cb, 36, 188, 760);
// p_r.add(new Chunk());
// ct.showTextAligned(cb, 0, p_r, counter, 788, 0);
cb.endLayer();
System.out.println("Y->"+ct.getYLine()+" - X->"+ct.getLastX());
p = new Phrase("and to check if it highlights text over two
lines.", new
Font(FontFamily.TIMES_ROMAN, 14, Font.NORMAL));
System.out.println("PhraseWidth->"+ct.getWidth(p));
ct.addText(p);
System.out.println("Y->"+ct.getYLine()+" - X->"+ct.getLastX());
ct.go();
System.out.println("Y->"+ct.getYLine()+" - X->"+ct.getLastX());
document.close();
}
...now I have another issue, how can I create a multipage pdf?
I have tried to append a long block of text but in the case that the text
overflows the page's bounds.
The part of text which does't fit is cutted off. How can put this text into
another page?
Once again, thanks a lot!!
