Member Function Documentation

◆ putChar()

void DeflateStream::putChar ( char  ch)

Output character.

Implements ipe::Stream.

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

◆ close()

void DeflateStream::close ( )

Close the stream. No more writing allowed!

Reimplemented from ipe::Stream.

◆ deflate()

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

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.
