- * 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. |
