Detailed Description

Stream writer implementation with no filters. This writer will write stream data as is with all original filters and no modifications to original data.

Member Function Documentation

void pdfobjects::utils::NullFilterStreamWriter::compress ( const Object &  obj,
Ref *  ref,
StreamWriter &  outStream 
) const [virtual]

Writes given stream object to the stream.

Parameters:
obj Stream object.
ref Indirect reference for object (NULL if direct).
outStream Stream where to write data.

Uses streamToCharBuffer with null_extractor extractor.

Implements pdfobjects::utils::FilterStreamWriter.

Referenced by pdfobjects::utils::FilterStreamWriter::getInstance().

unsigned char * pdfobjects::utils::NullFilterStreamWriter::null_extractor ( const Object &  obj,
size_t &  size 
) [static]

Extracts stream data without any decoding.

bool pdfobjects::utils::NullFilterStreamWriter::supportObject ( UNUSED_PARAM const Object &  obj  )  const [virtual]

Checks whether given object is supported.

Returns:
allways true as it can write all stream objects.
