1 jpgtn version 2 2 =============== 3 4 What is jpgtn? 5 -------------- 6 7 Jpgtn is a thumbnailer for JPEG images. 8 9 Jpgtn is based on "tnpic" by Russell Marks and on "gtnpic" by Willie 10 Daniel. "tnpic" was originally distributed as a utility with Marks' "zgv" 11 program. "gtnpic" was an attempt to clean up and expand upon the original 12 tnpic program and "maybe add some new features along the way." Jpgtn 13 differs from both tnpic and gtnpic in purpose. It is not an indexer. 14 15 Jpgtn only thumbnails JPEG images. I have no plans to change it to accept 16 other input formats. On and off I've thought about adding support for PNG 17 output but I haven't had a real need for it myself so I haven't done it. 18 19 Jpgtn can output thumbnails to files with names based on the names of the 20 input files, or it can dump to stdout. The stdout support can be a useful 21 feature for CGI applications. 22 23 Jpgtn is based in part on the work of the Independent JPEG Group. 24 25 26 27 What do I need to use it? 28 ------------------------- 29 30 In order to compile the source distribution you will need a C compiler. 31 32 You will also need the Independent JPEG Group's JPEG library, libjpeg. 33 It is a common library and it may already be installed on your system. 34 If you don't have libjpeg, it is freely available and links to the source 35 and documentation can be found on the Independent JPEG Group's page at 36 http://www.ijg.org/. 37 38 39 40 Compiling 41 --------- 42 43 Please see the INSTALL file! 44 45 46 Contact Info 47 ------------ 48 49 Email: jeremymadea@mindspring.com 50 Web: http://jeremymadea.home.mindspring.com/ 51 52 53 54----- 55 56Copyright 2002 Jeremy Madea 57 58This file is part of jpgtn. 59 60Jpgtn is free software; you can redistribute it and/or modify 61it under the terms of the GNU General Public License as published by 62the Free Software Foundation; either version 2, or (at your option) 63any later version. 64 65Jpgtn is distributed in the hope that it will be useful, 66but WITHOUT ANY WARRANTY; without even the implied warranty of 67MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
