no, you'd need to generate a new content stream for the Normal Appearance using http://pdfbox.apache.org/docs/2.0.3/javadocs/org/apache/pdfbox/pdmodel/PDPageContentStream.html#PDPageContentStream(org.apache.pdfbox.pdmodel.PDDocument,%20org.apache.pdfbox.pdmodel.interactive.annotation.PDAppearanceStream) With that in place you could then use PDPageContentStream.drawImage(PDImageXObject image, Matrix matrix) BR Maruan > > On Tue, Oct 11, 2016 at 11:34 AM, Maruan Sahyoun <[email protected]> > wrote: > >> Hi, >> >>> Am 11.10.2016 um 11:29 schrieb Gilad Denneboom < >> [email protected]>: >>> >>> Here's what I have so far (I skipped the scaling part, just to see if I >> can >>> get any kind of results...): >>> >>> // - load your image as a PDXObjectImage >>> BufferedImage bImg = ImageIO.read(new >>> File(imageFilePath)); >>> PDXObjectImage image = new PDJpeg(doc, bImg); >>> COSStream s = image.getCOSStream(); >>> >>> // - create a PDXObjectForm with the image as a >>> resource entry >>> PDXObjectForm objectForm = new PDXObjectForm(s); >>> PDResources resources = new PDResources(); >>> resources.addXObject(objectForm, "Im0"); >>> objectForm.setResources(resources); >>> >>> // - put that into the /I key of the fields MK entry >>> >>> f.getWidget().getAppearanceCharacteristics().getDictionary().setItem( >> COSName.I, >>> objectForm); >>> >>> // - add the PDXObjectForm you created above to the >>> Resources Entry of the appearance stream >>> PDAppearanceStream ap = (PDAppearanceStream) >>> f.getWidget().getAppearance().getNormalAppearance().get("default"); >>> Map<String, PDXObject> xobjectsMap = >>> ap.getResources().getXObjects(); >>> xobjectsMap.put("FRM", objectForm); >>> >>> f.getWidget().getAppearance().getNormalAppearance().put("default", ap); >>> >>> Do you see what I'm doing wrong, because the button is still blank when I >>> open the edited file? … >> >> from the code you are not setting the appearance stream content.
