Here's the code to replace images in PDFs. It will replace
the first image in the first page.
PdfReader pdf = new PdfReader("in.pdf");
PdfStamper stp = new PdfStamper(pdf, new
FileOutputStream("c:\\out.pdf"));
PdfWriter writer = stp.getWriter();
Image img = Image.getInstance("image.png");
PdfDictionary pg = pdf.getPageN(1);
PdfDictionary res =
(PdfDictionary)PdfReader.getPdfObject(pg.get(PdfName.RESOURCES));
PdfDictionary xobj =
(PdfDictionary)PdfReader.getPdfObject(res.get(PdfName.XOBJECT));
if (xobj != null) {
for (Iterator it = xobj.getKeys().iterator(); it.hasNext();) {
PdfObject obj = xobj.get((PdfName)it.next());
if (obj.isIndirect()) {
PdfDictionary tg =
(PdfDictionary)PdfReader.getPdfObject(obj);
PdfName type =
(PdfName)PdfReader.getPdfObject(tg.get(PdfName.SUBTYPE));
if (PdfName.IMAGE.equals(type)) {
PdfReader.killIndirect(obj);
Image maskImage = img.getImageMask();
if (maskImage != null)
writer.addDirectImageSimple(maskImage);
writer.addDirectImageSimple(img,
(PRIndirectReference)obj);
break;
}
}
}
}
stp.close();

> Hi All,
> As far as I have digged, we can not directly modify the
> images in pdf file with iText. Although we can get the image
> data from the XObject. right?
> Actually I intend to create a new pdf from an existing one
> with some of the contained images changed/repalced with some other.
> As we can't replace image directly with iText, I have two
> options in mind to achieve this.
> a. Is it possible that I render the changed image (different
> image) on the existing image position to give the effect that
> image is actually changed.
> b. Other could be, if possible, I create new pdf from the
> existing one and all the pdf objects to new one except the
> images to be modified. In place of these images I can add my
> changed images to new pdf.
>
> Please guide if any of this is feasible, please share if you
> have any other option in mind.
>
> Any help would be greatly appreciated.

> Thanks
