Hi Mike, Source of "jaggies" found and fixed. Here is the fastest way for you to implement the change I just made so you can retest (NB: I have already updated the SCMI AGET server on lead.unidata.ucar.edu and put a new v2017 compressed tar file out in our McIDAS downloads area): <as 'mcidas' on the machine where you built the v2017 release> cd ~mcidas/mcidas2017/src -- edit scmiaget.cp and at line 836: insert: tprintf( dbg, "%s:: input bytes_per_pix = %d", server, read.bytppix ); so that this block now reads: #if DEBUG_SEND tprintf( dbg, "%s:: input bytes_per_pix = %d", server, read.bytppix ); tprintf( dbg, "%s:: output bytes_per_pix = %d", server, bytes_per_pix ); #endif -- change line 846 from: switch ( read.bytppix ) { to read: switch ( bytes_per_pix ) { -- after exiting your editor, rebuild and "install" the scmiaget ADDE server: make scmiaget && rm ~/bin/scmiaget && ln scmiaget ~/bin Finally, rerun your IMGDISP and IMGREMAP tests and let me know your results. Comment: dumb, Dumb, DUMB mistake on my part! :-( Cheers, Tom -- **************************************************************************** Unidata User Support UCAR Unidata Program (303) 497-8642 P.O.
