Member Function Documentation

putChar()

void DeflateStream::putChar ( char  ch )

virtual

Output character.

Implements ipe::Stream.

References ipe::Buffer::data(), deflate(), ipe::Stream::putRaw(), and ipe::Buffer::size().

close()

void DeflateStream::close ( )

virtual

Close the stream. No more writing allowed!

Reimplemented from ipe::Stream.

References ipe::Stream::close(), ipe::Buffer::data(), deflate(), ipe::Stream::putRaw(), and ipe::Buffer::size().

deflate()

Buffer DeflateStream::deflate ( const char *  data, int  size, int &  deflatedSize, int  compressLevel  )

static

Deflate a buffer in a single run.

The returned buffer may be larger than necessary: deflatedSize is set to the number of bytes actually used.
