<P><FONT SIZE=2 FACE="Arial">Hi,</FONT>
</P>
<P><FONT SIZE=2 FACE="Arial">I can display some mrsid files using mapserver normal release binaries from <A HREF="http://hobo.stat.iastate.edu/mapserver/">http://hobo.stat.iastate.edu/mapserver/</A>. Seems to depend on how the mrsid files were made up or their size. I can see 2mb sid files easly (w45a03.sid) but not 50mb files(w55d.sid).</FONT></P>
<P><FONT SIZE=2 FACE="Arial">here is the info on the sid files, apart from size the only other difference is dyn range min and dyn range max values which are set at natural in the non displaying sid file, maybe no color range therefore no display. any clues.</FONT></P>
<P><FONT SIZE=2 FACE="Arial">is the complete mrsid file loaded into memory on the server or only the portion that is in the view before being sent as a gif , my output format? </FONT></P>
