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)
http://www.ijg.org/
PNG Reference Library (libpng)
http://www.libpng.org/pub/png/
zlib Compression Library
http://www.zlib.net/
Haru Free PDF Library (libharu)
http://sourceforge.net/projects/libharu/
CxImage
http://www.codeproject.com/bitmap/cximage.asp
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.
