+{ TCompressionStream compresses data on the fly as data is written to it, and

+
+ TCompressionStream is write-only and strictly sequential. Reading from the
+ stream will raise an exception. Using Seek to move the stream pointer
+ will raise an exception.
+
+ Output data is cached internally, written to the output stream only when
+ the internal output buffer is full. All pending output data is flushed
+ when the stream is destroyed.
+
+ The Position property returns the number of uncompressed bytes of
+ data that have been written to the stream so far.
+
+ CompressionRate returns the on-the-fly percentage by which the original
+ data has been compressed: (1 - (CompressedBytes / UncompressedBytes)) * 100
+ If raw data size = 100 and compressed data size = 25, the CompressionRate
+ is 75%
+
+ The OnProgress event is called each time the output buffer is filled and
+ written to the output stream. This is useful for updating a progress
+ indicator when you are writing a large chunk of data to the compression
+ stream in a single call.}

+{ TDecompressionStream decompresses data on the fly as data is read from it.
+
+ Compressed data comes from a separate source stream. TDecompressionStream
+ is read-only and unidirectional; you can seek forward in the stream, but not
+ backwards. The special case of setting the stream position to zero is
+ allowed. Seeking forward decompresses data until the requested position in
+ the uncompressed data has been reached. Seeking backwards, seeking relative
+ to the end of the stream, requesting the size of the stream, and writing to
+ the stream will raise an exception.
+
+ The Position property returns the number of bytes of uncompressed data that
+ have been read from the stream so far.
+
+ The OnProgress event is called each time the internal input buffer of
+ compressed data is exhausted and the next block is read from the input stream.
+ This is useful for updating a progress indicator when you are reading a
+ large chunk of data from the decompression stream in a single call.}

+
+Overview
+========
+
+This directory contains an update to the ZLib interface unit,
+distributed by Borland as a Delphi supplemental component.
+
+The original ZLib unit is Copyright (c) 1997,99 Borland Corp.,
+and is based on zlib version 1.0.4. There are a series of bugs
+and security problems associated with that old zlib version, and
+we recommend the users to update their ZLib unit.
+
+
+Summary of modifications
+========================
+
+- Improved makefile, adapted to zlib version 1.2.1.
+
+- Some field types from TZStreamRec are changed from Integer to
+ Longint, for consistency with the zlib.h header, and for 64-bit
+ readiness.
+
+- The zlib_version constant is updated.
+
+- The new Z_RLE strategy has its corresponding symbolic constant.
+
+- The allocation and deallocation functions and function types
+ (TAlloc, TFree, zlibAllocMem and zlibFreeMem) are now cdecl,
+ and _malloc and _free are added as C RTL stubs. As a result,
+ the original C sources of zlib can be compiled out of the box,
+ and linked to the ZLib unit.
+
+
+Suggestions for improvements
+============================
+
+Currently, the ZLib unit provides only a limited wrapper around
+the zlib library, and much of the original zlib functionality is
+missing. Handling compressed file formats like ZIP/GZIP or PNG
+cannot be implemented without having this functionality.
+Applications that handle these formats are either using their own,
+duplicated code, or not using the ZLib unit at all.
+
+Here are a few suggestions:
+
+- Checksum class wrappers around adler32() and crc32(), similar
+ to the Java classes that implement the java.util.zip.Checksum
+ interface.
+
+- The ability to read and write raw deflate streams, without the
+ zlib stream header and trailer. Raw deflate streams are used
+ in the ZIP file format.
+
+- The ability to read and write gzip streams, used in the GZIP
+ file format, and normally produced by the gzip program.
+
+- The ability to select a different compression strategy, useful
+ to PNG and MNG image compression, and to multimedia compression
+ in general. Besides the compression level
+
+ TCompressionLevel = (clNone, clFastest, clDefault, clMax);
+
+ which, in fact, could have used the 'z' prefix and avoided
+ TColor-like symbols
+
+ TCompressionLevel = (zcNone, zcFastest, zcDefault, zcMax);
+
+ there could be a compression strategy
+
+ TCompressionStrategy = (zsDefault, zsFiltered, zsHuffmanOnly, zsRle);
+
+- ZIP and GZIP stream handling via TStreams.
