2021-01-02Add several methods for working with form XObjects (fixes #436)Jay Berkenbilt
Make some more methods in QPDFPageObjectHelper work with form XObjects, provide forEach methods to walk through nested form XObjects, possibly recursively. This should make it easier to work with form XObjects from user code.

2021-01-02QPDFPageObjectHelper: filterPageContents -> filterContents + form XObjectJay Berkenbilt

2020-12-28Add QPDFObjectHandle::setFilterOnWriteJay Berkenbilt
2020-12-28Add ostream << for QPDFObjGenJay Berkenbilt
2020-12-28Let optimize filter stream parameters instead of making them directJay Berkenbilt
Also removes preclusion of stream references in stream parameters of filterable streams and reduces write times by about 8% by eliminating an extra traversal of the objects.
2020-12-28Implement user-provided stream filtersJay Berkenbilt
Refactor QPDF_Stream to use stream filter classes to handle supported stream filters as well.
2020-12-26Add QPDFObjectHandle::makeDirect(bool allow_streams)Jay Berkenbilt

2020-11-04Ignore unused field in xref entry, avoiding range error (fixes #482)Jay Berkenbilt
2020-10-31Prepare 10.0.3 releaserelease-qpdf-10.0.3Jay Berkenbilt
2020-10-31Fix stack overflow on direct root (fuzz issue 26761)Jay Berkenbilt
2020-10-31Fix foreign stream copying bug (fixes #478)Jay Berkenbilt
This reverts an incorrect fix to #449 and codes it properly. The real problem was that we were looking at the local dictionaries rather than the foreign dictionaries when saving the foreign stream data. In the case of direct objects, these happened to be the same, but in the case of indirect objects, the object references could be pointing anywhere since object numbers don't match up between the old and new files.
2020-10-27Prepare 10.0.2 releaserelease-qpdf-10.0.2Jay Berkenbilt
2020-10-27Revert removal of unreadCh change for performanceJay Berkenbilt
Turns out unreadCh is much more efficient than seek(-1, SEEK_CUR). Update comments and code to reflect this.

2020-10-25Use sha256 for signing release filesJay Berkenbilt
2020-10-25Build Windows releases with openssl; automate external librariesJay Berkenbilt
External libraries for Windows are now built automatically in the qpdf/external-libs repository and include openssl in addition to zlib and jpeg. Use these, and update the Windows build to build with the openssl crypto provider by default. We leave the native crypto provider enabled in case there is a problem with openssl and also to continue to exercise that code.

2020-10-22Obscure bug fix copying foreign streams in special cases (fixes #449)Jay Berkenbilt
Specifically, if a stream had its stream data replaced and had indirect /Filter or /DecodeParms, it would result in non-silent loss of data and/or internal error.
