Hi all,
I'm working on the generation of few reports with iText.
I'm completely stuck trying to understand what's going on and I have no
more ideas on how to debug it.
Basically I produce a series of PDFs (1 or more pages) and afterwards I
want to add a watermark.
It seems working good if I use the getUnderContent from the PDFStamper, but
this correctly put my watermark in the background.
I want my text (or image) in the top layer, so I tried to use
getOverContent.
And here the weird behaviour: when I try to rotate it (text) the rotation
is correct for few pages and is 90 degrees wrong for others!
I cannot understand where's the issue here as I've checked rotation for all
the pages and is 90 degrees for all of them.
private void addDraftWatermark(String filename) throws IOException,
DocumentException {
File subClientFolder = new File(filename);
if (subClientFolder.exists() && subClientFolder.list().length > 0) {
for (File folder : subClientFolder.listFiles()) {
File[] listPDFs = folder.listFiles();
for (File pdf : listPDFs) {
String realFilename = pdf.getAbsolutePath();
PdfReader reader = new PdfReader(realFilename);
String draftFilePath = pdf.getParent() + "\\draft - " +
pdf.getName();
PdfStamper stamper = new PdfStamper(reader, new
FileOutputStream(draftFilePath));
// Properties properties = new Properties();
//
properties.load(AbstractReport.class.getResourceAsStream("/kobalt/sax/reports/properties/javareports.properties"));
// String temp = (String)
properties.get("imagelocationdev");
// Image img = Image.getInstance((String)
properties.get("imagelocationdev") + "draftwatermark.png");
// img.setAbsolutePosition(150, 60);
PdfContentByte wtmk;
BaseFont bf =
BaseFont.createFont(BaseFont.HELVETICA_BOLD, BaseFont.CP1250,
BaseFont.NOT_EMBEDDED);
int total = reader.getNumberOfPages() + 1;
for (int i = 1; i < total; i++) {
wtmk = stamper.getOverContent(i);
//image
// wtmk.addImage(img);
//text
// PdfGState gState = new PdfGState();
// gState.setFillOpacity(0.4f);
// wtmk.setGState(gState);
wtmk.beginText();
wtmk.setFontAndSize(bf, 200);
wtmk.setRGBColorFill(0xC8, 0xB4, 0xB4); // rotation
wtmk.showTextAligned(PdfContentByte.ALIGN_LEFT,
"DRAFT", 140, 90, 25);
// test
int rotation = reader.getPageRotation(1);
Rectangle box =
wtmk.getPdfWriter().getBoxSize("media");
wtmk.endText();
}
stamper.close();
reader.close();
pdf.delete();
File draft = new File(draftFilePath);
draft.renameTo(new File(realFilename));
}
}
}
}
I'll really appreciate any suggestion.
Thanks,
Diego
