Dear gurus:
Could anybody, please, advise me where I can find a program for UNIX to convert
a 16 bit binary grayscale image (i.e a file with say 256*256 short int) to one
of the following formats : GIF, JPEG, TIFF, PBM, PGM, PPM, X11 bitmap, Utah Raster Toolkit RLE, PDS/VICAR, Sun Rasterfile, PM.

#include <stdio.h>

/*

 * Copyright abandoned.
 */

main()

{

    short int inbuffer[256 * 256];
    char outbuffer[256 * 256];
    int i;

    fread( inbuffer, sizeof( short int ), 256 * 256, stdin );

    for ( i = 0; i < 256 * 256; i++ )
	outbuffer[i] = inbuffer[i] >> 8;

    printf( "P5\n256 256\n255\n" );
    fwrite( outbuffer, sizeof( char ), 256 * 256, stdout );

    exit( 0 );

}

Error checking and enhancements are left as an exercise for the student.

I mean, it ain't that difficult...
