Signature fields in OpenOffice for tablet handwriting, not digital signature
I want to place a "signature box" in my OpenOffice doc.
I need this for iOS / gPlay "PDF Forms" app for signing PDF documents on touch screens (handwriting / pen).
According to their FAQ, I need a signature on my OO document, but even after hours of research, I am still not now if OO offers such a field. I only find text boxes or digital signatures / certificates.
Do you have a hint of me?
Thanks, Christian

It seems OpenOffice only has a subset of the available fields and the signature field is not available.
Now I will add a text field, naming it something like fldSignature1 and using iText, I will change every field starting with "fldSignature" programmatically with a signature field
UPDATE: here is the code that I am using with success as I said, I created a form where I placed a textbox that acts as a placeholder for the signature field, in my example I named it fldFirma, you can put the substitution code in a loop to change any field that contains a prefix, etc.
here's the code
String filename = Environment.getExternalStorageDirectory().getPath() + "/testpdf.pdf";
String filenameOut = Environment.getExternalStorageDirectory().getPath() + "/testpdfCompiled.pdf";
PdfReader reader = new PdfReader(filename);
PdfStamper stamper = new PdfStamper(reader, new FileOutputStream(filenameOut), '\0', true);
AcroFields fields = stamper.getAcroFields();
fields.setGenerateAppearances(true);
String[] fieldsNames = (String[]) fields.getFields().keySet().toArray(new String[fields.getFields().keySet().size()]);
for (String fieldName : fieldsNames) {
if (fieldName.equals("fldFirma")) { //change this part with your logic to identify the signature field
List<FieldPosition> fieldPositions = fields.getFieldPositions(fieldName);
AcroFields.FieldPosition fieldPosition = fieldPositions.get(0);
// i remove the "placeholder field"
fields.removeField(fieldName);
// and place at its position, the new empty signature field
stamper.addSignature(
fieldName,
fieldPosition.page,
fieldPosition.position.getLeft(),
fieldPosition.position.getTop(),
fieldPosition.position.getRight(),
fieldPosition.position.getBottom()
);
}
}
// close pdf stamper
// stamper.setFormFlattening(true);
stamper.close();
stamper.close();
reader.close();
