Subject: [iText-questions] Image appears 0.5cm off correct Y coordinate when
printed
Hi,
I'm creating a Class that will be used to stamp headers, footers and
barcodes on existing documents and to do this I intend to use a
PDFStamper.
I am aware that the (0,0) co-ordinate in I-Text is at the bottom left
corner
and so assuming I want to add a picture at X=10cm and Y=25cm I have
written
some code as follows:
double xInMM=100;
double yInMM=250;
double mmToPoint=2.834644567;
float xInPoints=(float)(xInMM*mmToPoint);
float yInPoints=(float)(yInMM*mmToPoint);
PdfReader reader = new PdfReader("C://input.pdf");
PdfStamper stamp = new PdfStamper(reader, new
FileOutputStream("C://output.pdf"));
Image img = Image.getInstance("C://square.bmp");
img.setAbsolutePosition(xInPoints, yInPoints);
// text over the existing page
PdfContentByte over = stamp.getOverContent(1);
over.addImage(img);
Having printed the 'stamped' document, I find that the X co-ordinate is
correct, yet the Y co-ordinate is approximately 1/2cm out, i.e. my square
appears at 24.5cm. Where is this offset coming from? Which object can I
use
to get hold of this value.
Many thanks,
Lloyd
