+ * TIFF Library.

+ * ZIP (aka Deflate) Compression Support

+ *

+ * This file is simply an interface to the zlib library written by

+ * Jean-loup Gailly and Mark Adler.  You must use version 1.0 or later

+ * of the library: this code assumes the 1.0 API and also depends on

+ * the ability to write the zlib header multiple times (one per strip)

+ * which was not possible with versions prior to 0.95.  Note also that

+ * older versions of this codec avoided this bug by supressing the header

+ * entirely.  This means that files written with the old library cannot

+ * be read; they should be converted to a different compression scheme

+ * and then reconverted.

+ *

+ * The data format used by the zlib library is described in the files

+ * zlib-3.1.doc, deflate-1.1.doc and gzip-4.1.doc, available in the

+ * directory ftp://ftp.uu.net/pub/archiving/zip/doc.  The library was

+ * last found at ftp://ftp.uu.net/pub/archiving/zip/zlib/zlib-0.99.tar.gz.
