Depending on what you intend to use the image for, I agree that using Mapserver might be the best solution for doing this, especially since generating the legend would be trivial.<br>

Hi everyone,<br> Is there any easy way to do the following using C++ in GDAL: I have a floating-point image and I'd like to associate arbitrary colors with ranges of the pixel levels. For example: for the pixel values in [0,0.1) associate red, for [0.1, 0.2) associated orange, for [0.2, 0.3) associate light blue, for [0.3,0.4) associate dark blue, for [0.4, 0.5) associate green, etc. I would like also to have this information available in the metadata or as legend so that users know what the colors stand for when they view the image.<br>
<br> Thanks a lot in advance for any input.<br><br> With best regards.<br>Belaid Moa.<br><br> <br><br><hr>Create a cool, new character for your Windows Live™ Messenger. <a href="http://go.microsoft.com/?linkid=9656621">Check it out</a></div>
