[McIDAS #JGN-249914]: IMGMAKE



Hi Mike,

Yet another tweak for you to test:

<as 'mcidas'>
cd ~mcidas/mcidas2017/src

-- edit scmiaget.cp

   change lines 617-625

   from:

        /* <<<<< UPC mod 20171223 - size of line buffer must be large enough
                 to hold the maximum input and output line sizes >>>>> */

        line_size = read.maxele  *             /* # elems in a image line  */
                    read.bytppix +             /* # bytes per element      */
                    aradir[14];                /* length of line prefix    */

        line_size = max( line_size, bytes_per_line );

    to:

        /* <<<<< UPC mod 20171223 - size of line buffer must be large enough
                 to hold the maximum input and output line sizes, AND factor
                 of 2 is to account for 4-byte ints vs 2-byte short >>>>> */

        line_size = read.maxele  *             /* # elems in a image line  */
                    read.bytppix +             /* # bytes per element      */
                    aradir[14];                /* length of line prefix    */

        line_size = 2 * max( line_size, bytes_per_line );

    The changes are to update the documentation and multiply the final line_size
    by 2.

-- save edit changes

make scmiaget && rm ~/bin/scmiaget && ln scmiaget ~/bin

I made the change on lead.unidata.ucar.edu and then IMGCOPYed each Mesoscale-1
band to a local dataset on my test machine as a test, and I had no problems.

I was going to put a new McIDAS-X/-XCD distribution out in the Downloads area
of our website for folks to grab, but I ran into a missing entry point that
is called by an updated routine in SSEC XCD v2017.2.  I'll need to figure
out if I missed the code change somewhere (I don't think so), or if SSEC
released a broken version of XCD v2017.2.  I did put out new distributions
of mcidasx2017.tar.gz and mcupdate.tar.gz, but I will need to yank them
as one can not build the XCD component because of the missing entry
point.

Please let me know if the tweak in scmiaget.cp works for you.

Cheers,

Tom
