    I have a 2-D data, with valid range [-20.2,709.2],fillvalue=-100. Is there any keyword for Image function to control the display of the fillvalue, eg. fill the fillvalue pixels with white color, and display the other valid values with a continuous color table.

    I don't believe the Image() function has this capability. You could use MISSING_*** keywords to cgImage in the Coyote Library, if you wanted an alternative: http://www.idlcoyote.com/...doc/cg/cgimage.html.
