## Static Public Member Functions
static Buffer | deflate (const char *data, int size, int &deflatedSize, int compressLevel)

## Detailed Description

Filter stream adding flate compression.

## Constructor & Destructor Documentation

## ◆ DeflateStream()

DeflateStream::DeflateStream | ( | Stream & | stream,
|  | int | level
| ) |  |

## ◆ ~DeflateStream()

DeflateStream::~DeflateStream | ( |  | ) |
| virtual

## Member Function Documentation

## ◆ putChar()

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

Output character.

Implements ipe::Stream.

## ◆ 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().

Referenced by ipe::PdfWriter::createPageView(), and ipe::Document::save().

## ◆ 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.
