Detailed Description

FlateEncode filter can be used to compress any data stream using Flate (i.e. ZIP) compression method.

Constructor & Destructor Documentation

pdftron::Filters::FlateEncode::FlateEncode ( Filter  input_filter,
int  compression_level = -1,
size_t  buf_sz = 256 
)

Constructor for Flate encoder.

Parameters
input_filterthe input data stream
compression_levelmust be a number between 0 and 9: 1 gives best speed, 9 gives best compression, 0 gives no compression at all (the input data is simply copied a block at a time), -1 requests a default compromise between speed and compression (currently equivalent to level 6).
buf_szfilter buffer size (in bytes).
