McIDAS allows you to change the background of graphic plots to white, so you don't need to do this with another package. Try, for example: SF 1 SFCMG KDEN GU MAKE 0 WHITE SVGIF 1 test.gif >However, I obtained the latest relaese of ImageMagick >(ver 4.27) for our Sparc and it will not perform >the conversion properly, -negate -mnochrome produces a >completely black image on a GEMPAK(GARP) image with a >black background.

I also >tried IM 4.27 on another Solaris Intel machine with >the same results. > >Are there any other image viewer/converters out there >that can also be run from the command line for >use in scripts? I will also look for an older version >of ImageMagick.
