Hello Brad.
I was just looking at the API Documentation and it referred to this class
is a way that I would expect to be able to use it. Going off the cpp file
comments you pass a unfiltered stream to this class and it passes a
filtered copy of that stream to the PdfOutputStream argument. I know the
alternative. My only confusion here surrounds the fact that it is listed in
the API documentation and from what I can see there is no mention of it
being used only internally. But if I look at the code in the
PdfFilters.cpp file I can see that it is used internally, as you have
mentioned above.
*PdfOutputStream* PdfFilterFactory::CreateDecodeStream( const TVecFilters &
filters, PdfOutputStream* pStream,*
* const
PdfDictionary* pDictionary ) *
*{*
* TVecFilters::const_reverse_iterator it = filters.rbegin();*
* PODOFO_RAISE_LOGIC_IF( !filters.size(), "Cannot create an DecodeStream
from an empty list of filters" );*
* // TODO: support arrays and indirect objects here and the short name
/DP*
* if( pDictionary && pDictionary->HasKey( "DecodeParms" ) &&
pDictionary->GetKey( "DecodeParms" )->IsDictionary() )*
* pDictionary = &(pDictionary->GetKey( "DecodeParms"
)->GetDictionary());*
* PdfFilteredDecodeStream* pFilter = new PdfFilteredDecodeStream(
pStream, *it, false, pDictionary );*
* ++it;*
* while( it != filters.rend() ) *
* {*
* pFilter = new PdfFilteredDecodeStream( pFilter, *it, true,
pDictionary );*
* ++it;*
* }*
return pFilter;
}
