Detailed Description

An output stream that writes data to a memory buffer If the buffer is to small, it will be enlarged automatically.

DS: TODO: remove in favour of PdfBufferOutputStream.

Member Function Documentation

virtual void PoDoFo::PdfMemoryOutputStream::Close ( )

Close the PdfOutputStream. This method may throw exceptions and has to be called before the descructor to end writing.

No more data may be written to the output device after calling close.

Implements PoDoFo::PdfOutputStream.

pdf_long PoDoFo::PdfMemoryOutputStream::GetLength ( ) const
the length of the written data
char * PoDoFo::PdfMemoryOutputStream::TakeBuffer ( )
a handle to the internal buffer.

The internal buffer is now owned by the caller and will not be deleted by PdfMemoryOutputStream. Further calls to Write() are not allowed.

The caller has to free() the returned malloc()'ed buffer!

pdf_long PoDoFo::PdfMemoryOutputStream::Write ( const char *  pBuffer,
pdf_long  lLen 

Write data to the output stream

pBufferthe data is read from this buffer
lLenthe size of the buffer
the number of bytes written, -1 if an error ocurred

Implements PoDoFo::PdfOutputStream.
