These + new API calls make it possible for applications to go into PDF + files created by qpdf and make changes to them that go beyond + working with the PDF at the object level. The specific use case + for these changes was to write an external tool to perform digital + signature, but there could be other uses as well. New methods + include the following, all of which are described in their + respective headers: + - QPDF::getXRefTable() + - QPDFObjectHandle::getParsedOffset() + - QPDFWriter::getRenumberedObjGen(QPDFObjGen) + - QPDFWriter::getWrittenXRefTable() + 2019-10-12 Jay Berkenbilt <ejb@ql.org> * 9.0.2: release |
