Note to people including qpdf in distributions: the
|
||||
<filename>.la</filename> files generated by libtool are now
|
||||
installed by qpdf's <command>make install</command> target.
|
||||
Before, they were not installed. This means that if your
|
||||
distribution does not want to include <filename>.la</filename>
|
||||
files, you must remove them as part of your packaging process.

Major enhancement: API enhancements have been made to support
|
||||
parsing of content streams. This enhancement includes the
|
||||
following changes:

<para>
|

<function>QPDFObjectHandle::parseContentStream</function>
|

method parses objects in a content stream and calls
|
||||
handlers in a callback class. The example
|
||||
<filename>examples/pdf-parse-content.cc</filename>
|
||||
illustrates how this may be used.

Method <function>QPDFObjectHandle::getTypeCode()</function>
|
||||
returns an enumerated type value representing the
|
||||
underlying object type. Method
|
||||
<function>QPDFObjectHandle::getTypeName()</function>
|
||||
returns a text string describing the name of the type of a
|
||||
<type>QPDFObjectHandle</type> object. These methods can be
|
||||
used for more efficient parsing and debugging/diagnostic
|
||||
messages.

<command>qpdf --check</command> now parses all pages' content

streams in addition to doing other checks. While there are

still many types of errors that cannot be detected, syntactic

errors in content streams will now be reported.

All C-style casts in C++ Code have been replaced by C++
|
||||
casts, and many casts that had been included to suppress
|
||||
higher warning levels for some compilers have been removed,
|
||||
primarily for clarity. Places where integer type coercion
|
||||
occurs have been scrutinized. A new casting policy has
|
||||
been documented in the manual. This is of concern mainly
|
||||
to people porting qpdf to new platforms or compilers. It
|
||||
is not visible to programmers writing code that uses the
|
||||
library

Some internal limits have been removed in code that
|
||||
converts numbers to strings. This is largely invisible to
|
||||
users, but it does trigger a bug in some older versions of
|
||||
mingw-w64's C++ library. See
|
||||
<filename>README-windows.txt</filename> in the source
|
||||
distribution if you think this may affect you. The copy of
|
||||
the DLL distributed with qpdf's binary distribution is not
|
||||
affected by this problem.

The RPM spec file previously included with qpdf has been
|

removed. This is because virtually all Linux distributions
|

include qpdf now that it is a dependency of CUPS filters.

Overridden compressed objects are properly handled.
|
||||
Before, there were certain constructs that could cause qpdf
|
||||
to see old versions of some objects. The most usual
|
||||
manifestation of this was loss of filled in form values for
|
||||
certain files.
