Utility Warrior would like to thank the following companies/entities/individuals for providing software that can be used royalty free, this is one reason why we can offer our utilities at such low prices:
Independent JPEG Group (libjpeg) see http://www.ijg.org/ for details.
PNG Reference Library (libpng) see http://www.libpng.org/pub/png/ for details.
zlib Compression Library see http://www.zlib.net/ for details.
Haru Free PDF Library (libharu) see http://sourceforge.net/projects/libharu/ for details.
CxImage see http://www.codeproject.com/bitmap/cximage.asp for details.
LibTIFF see http://www.remotesensing.org/libtiff for details.
NB. We fully disclose the use of any third party code (see above) that we integrate into our utilities - even when no acknowledgement is required! We do not try to hide the fact that we build upon the work of others (or that we "stand on the shoulders of giants" to quote Isaac Newton). We hope that you find this attitude a refreshing change.
