Detailed Description

Input stream IStream wrapper for C2paStream.

This class is used to wrap an input stream for use with the C2PA library.

Constructor & Destructor Documentation

CppIStream() [1/3]

template<typename IStream >

c2pa::CppIStream::CppIStream ( IStream &  istream )

inlineexplicit

Construct an input stream wrapper from a std::istream-derived object.

Template Parameters

IStream

Type derived from std::istream.

Parameters

istream

The input stream to wrap (must be open and valid).

Exceptions

C2paException

if stream wrapper creation fails.

                                              {
            static_assert(std::is_base_of<std::istream, IStream>::value,
                      "Stream must be derived from std::istream");
            c_stream = c2pa_create_stream(reinterpret_cast<StreamContext *>(&istream), reader, seeker, writer, flusher);
            if (c_stream == nullptr) {
                throw C2paException("Failed to create input stream wrapper: is stream open and valid?");
            }
