 \section{\class{wxZlibInputStream}}\label{wxzlibinputstream}
 
+This stream uncompresses all data read from it. It uses the "filtered"
+stream to get new compressed data.
+
+The stream is not seekable, \helpref{SeekI()}{wxinputstreamseeki} returns
+ {\it wxInvalidOffset}. Also \helpref{GetSize()}{wxstreambasegetsize} is
+not supported, it always returns $0$.

 \section{\class{wxZlibOutputStream}}\label{wxzliboutputstream}
 
+This stream compresses all data written to it, and passes the compressed data
+to the "filtered" stream.
+
+The stream is not seekable, \helpref{SeekO()}{wxoutputstreamseeko} returns
+ {\it wxInvalidOffset}.

+\func{}{wxZlibOutputStream}{\param{wxOutputStream\&}{ stream}, \param{int}{ level = -1}, \param{int}{ flags = 0}}
+
+Creates a new write-only compressed stream. {\it level} means level of 
+compression. It is number between 0 and 9 (including these values) where
+0 means no compression and 9 best but slowest compression. -1 is default
+value (currently equivalent to 6).
+
+{\it flags} should be omitted for normal usage. The flag {\it wxZLIB\_NO_HEADER}
+ suppresses the generation of the zlib header and checksum, and is required
+when wxZlibOutputStream is used as a 'deflate' compressor for gzip or zip files.
+
+The following symbols can be use for the compression level and flags:
+
+\begin{verbatim}
+// Compression level
+enum {
+    wxZ_DEFAULT_COMPRESSION = -1,
+    wxZ_NO_COMPRESSION = 0,
+    wxZ_BEST_SPEED = 1,
+    wxZ_BEST_COMPRESSION = 9
+}
+
+// Flags
+enum {
+    wxZLIB_NO_HEADER = 1   // required for use in Gzip and Zip files
+}
+\end{verbatim}
