Huge warning about podofo : they have no binary/source compatibility guarantee.
It could be complicated to maintain a filter using podofo, except if they
improve this.
And even between minor releases, things could break.
For instance : their GetObjectLength got a new mandatory parameter in 0.8.3,
hence this kind of code :
#if (PODOFO_VERSION_MAJOR > 0) || (PODOFO_VERSION_MINOR > 8) ||
(PODOFO_VERSION_PATCH >= 3)
if (obj->HasStream() && (obj-
>GetObjectLength(PoDoFo::ePdfWriteMode_Compact) > 10000)) {
#else
if (obj->HasStream() && (obj->GetObjectLength() > 10000)) {
#endif
