Hi,
sorry but I don't know what is 'media box'. To generate PDF from TIFF, I use
this code:
public IDfDocument tiffToPdf(IDfDocument doc) throws DfException {
if (!doc.getContentType().equals("tiff")) {
System.out.println("Doc isn't tiff document");
return null;
}
String tiff_file = doc.getObjectName();
String pdf_file;
if (tiff_file.lastIndexOf('.') >= 0) {
pdf_file = tiff_file.substring(0, tiff_file.lastIndexOf('.') + 1) + "pdf";
}
else {
pdf_file = tiff_file + ".pdf";
}
Document document = null;
PdfWriter writer = null;
PdfContentByte cb = null;
ByteArrayInputStream bais = doc.getContent();
ByteArrayOutputStream baos = new ByteArrayOutputStream();
try {
int pages = 0;
RandomAccessFileOrArray ra = null;
int comps = 0;
try {
ra = new RandomAccessFileOrArray(bais);
comps = TiffImage.getNumberOfPages(ra);
}
catch (Throwable e) {
System.out.println("Exception in " + tiff_file + " " + e.getMessage());
return null;
}
System.out.println("Processing: " + tiff_file);
for (int c = 0; c < comps; ++c) {
try {
Image img = TiffImage.getTiffImage(ra, c + 1);
if (img != null) {
System.out.println("page " + (c + 1));
img.setAbsolutePosition(0, 0);
if (document == null) {
document = new Document(new Rectangle(img.getWidth(),
img.getHeight()));
writer = PdfWriter.getInstance(document, baos);
document.open();
cb = writer.getDirectContent();
}
cb.addImage(img);
document.newPage();
++pages;
}
}
catch (Throwable e) {
System.out.println("Exception " + tiff_file + " page " + (c + 1) + "
" + e.getMessage());
}
}
ra.close();
document.close();
IDfId newDocId = doc.saveAsNew(true);
IDfDocument newDoc = (IDfDocument) doc.getSession().getObject(newDocId);
newDoc.setContentEx(baos, "pdf", 0);
newDoc.setObjectName(pdf_file);
newDoc.save();
return newDoc;
}
catch (Throwable e) {
e.printStackTrace();
return null;
}
}
Thanks for any help.

Maybe you've added the image outside the media box.
Without more info, we can't help you.
