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 diff --git a/manual/qpdf-manual.xml b/manual/qpdf-manual.xml index e64f790b..96f8941e 100644 --- a/manual/qpdf-manual.xml +++ b/manual/qpdf-manual.xml @@ -4365,6 +4365,45 @@ print "\n"; </para> <variablelist> <varlistentry> + <term>9.1.0: XXX</term> + <listitem> + <itemizedlist> + <listitem> + <para> + Library Enhancements + </para> + <itemizedlist> + <listitem> + <para> + Incorporate contribution from Masamichi Hosoda to + properly handle signature dictionaries by not including + them in object streams, formatting the + <literal>/Contents</literal> key has a hexadecimal + string, and excluding the <literal>/Contents</literal> + key from encryption and decryption. + </para> + </listitem> + <listitem> + <para> + Incorporate contribution from Masamichi Hosoda to provide + new API calls for getting file-level information about + input and output files, enabling certain operations on + the files at the file level rather than the object level. + New methods include + <function>QPDF::getXRefTable()</function>, + <function>QPDFObjectHandle::getParsedOffset()</function>, + <function>QPDFWriter::getRenumberedObjGen(QPDFObjGen)</function>, + and <function>QPDFWriter::getWrittenXRefTable()</function>. + </para> + </listitem> + </itemizedlist> + </listitem> + </itemizedlist> + </listitem> + </varlistentry> + </variablelist> + <variablelist> + <varlistentry> <term>9.0.2: October 12, 2019</term> <listitem> <itemizedlist> |
