Hello Folks,
I'm trying insert a images on empty pages of pdf file existing. My code for
this purpose is the next:
pdfReader = new PdfReader("source.pdf");
pdfStamper = new PdfStamper("destination.pdf"));
for(Iterator<FinalPageImage>
itFinalPageImg=imgageList.iterator();itFinalPageImg.hasNext();){
FinalPageImage image = itFinalPageImg.next();
BufferedImage image = image.getImage();
Raster tmpRaster = image.getRaster();
DataBuffer db = tmpRaster.getDataBuffer();
byte[] bytes = new byte[db.getSize()];
// I need to do a transformation
for (int l_i = 0; l_i < bytes.length; l_i++) {
bytes[l_i] =
(byte)Math.round(db.getElemFloat(l_i)*(float)255);
}
PdfContentByte content =
pdfStamper.getOverContent(image.getPageNum());
Image iTextImg = Image.getInstance(tmpRaster.getWidth(),
tmpRaster.getHeight(), 4, 8, bytes);
iTextImg.setSmask(false);
iTextImg.setAbsolutePosition(0,0);
content.addImage(iTextImg);
}
pdfReader.close();
pdfStamper.close();
The result is nothing, the document destination page is blank. If I make a
document from scratch with pdfWriter the result is ok, the documents with
the image are dumped to file.
Could somebody help me, please?.
Thanks in advance.
