<p class="MsoNormal"><span style="font-size:11.0pt;color:#1F497D">Hi Asen: Hmmm… What version of MapServer and GDAL? The scaling should be happening in GDAL before the data hit MapServer so the [pixel] values MapServer gets are already between 0-255 in both
of your cases. What I don’t know is what GDAL does with values outside the scaling range – so with SCALE=10,20 what do 5 or 50 get mapped to.<o:p></o:p></span></p>
