It is the most used image compression used for web graphics. Typically, LZW can compress image files to about one-half their original size. Compression ratios of 5:1 are also obtainable when the image has long runs or a lot of solid color areas. LZW compression is always used in GIF image files, and offered as an option in TIFF. <h1> </h1> <P class="SubHeading"><a href="default.htm">Back to the Pocket PC 2002 Main Page</a></P> <P class="smallgraytxt-nonjust"> </P> <P class="smallgraytxt-nonjust"> </P> <P class="text"> <script language="JavaScript" type="text/JavaScript">  </script> <body> <P align="center"><span class="smallgraytxt-nonjust"><strong>LEADTOOLS Sales:</strong> 704-332-5532 | </span><a href="mailto:sales@leadtools.com" class="smallgraytext-nounder">sales@leadtools.com</a><span class="smallgraytxt-nonjust"><br> <strong>LEADTOOLS Support:</strong> 704-372-9681 |</span> <a href="mailto:support@leadtools.com" class="smallgraytext-nounder">support@leadtools.com </a></P> <P align="center"><a href="/Home2/vertmkts/LTProdOvrvw.htm" class="smallgraytext-nounder">Products</a> <span class="smallgraytxt-nonjust">| </span><a href="/Survey/WebEvalSurvey.asp" class="smallgraytext-nounder">Downloads</a><span class="smallgraytxt-nonjust"> | </span><a href="/Home2/general/ordermain.htm" class="smallgraytext-nounder">Order</a><span class="smallgraytxt-nonjust"> | </span><a href="/support/default.htm" class="smallgraytext-nounder">Support</a><span class="smallgraytxt-nonjust"> | </span><a href="/Home2/general/corporate.htm" class="smallgraytext-nounder">Corporate</a><span class="smallgraytxt-nonjust"> | </span><a href="/Home2/press/press.htm" class="smallgraytext-nounder">News</a></P> <map name="MapHeader"> <area shape="rect" coords="3,2,199,42" href="/Default.htm"> </map> </P> </TD> </TR> </TABLE></TD> </TR> </TABLE></TD> <TD class="whitetext"> <IMG src="../../images/04New-web-design_07.gif" width=5 height=389 alt=""></TD> </TR> <TR> <TD colspan="5" valign="top"> <DIV align="right"> <table width="50%" border="0" align="center" cellpadding="6" cellspacing="0"> <tr> <td><div align="center"> <p class="copyright">Copyright © 2009 All Rights Reserved.
