## Member Function Documentation

void DeflateStream::putChar | ( | char | ch | ) |
| virtual

Output character.

Implements ipe::Stream.

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

void DeflateStream::close | ( |  | ) |
| virtual

Close the stream. No more writing allowed!

Reimplemented from ipe::Stream.

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.
