Tilman Hausherr updated PDFBOX-2470:
------------------------------------
Description:
Hi
I have made the following modifications to avoid ClassCastException or
NullPointerException in addSignature(PDSignature sigObject, SignatureInterface
signatureInterface, SignatureOptions options) :
{code}
// Appearance Dictionary auslesen und setzen
// MOD_CS
// PDAppearanceDictionary ap =
// new
PDAppearanceDictionary((COSDictionary)cosBaseDict.getItem(COSName.AP));
// ap.getDictionary().setDirect(true);
// signatureField.getWidget().setAppearance(ap);
COSBase item = cosBaseDict.getItem(COSName.AP);
if (item instanceof COSObject) {
item = ((COSObject) item).getObject();
}
if (item instanceof COSDictionary) {
PDAppearanceDictionary ap = new
PDAppearanceDictionary((COSDictionary) item);
ap.getDictionary().setDirect(true);
signatureField.getWidget().setAppearance(ap);
}
// AcroForm DefaultRessource auslesen und setzen
COSBase dr = cosBaseDict.getItem(COSName.DR);
// MOD_CS
if (dr != null) {
dr.setDirect(true);
dr.setNeedToBeUpdate(true);
acroFormDict.setItem(COSName.DR, dr);
}
{code}
Regards
