In this assignment you will integrate your parser and your image
processing components.

Step (1) incorporate the imageop_t structure into image.h

typedef struct imageop_type
{
   int  opcode;
   char in0[64];           /* Primary input filename   */
   char in1[64];           /* Secondary input filename */
   char out[64];           /* Output file name         */

   int  dims[2];           // x, y dimensions of output
   double factor;
}  imageop_t;

Step (2) change the main.c module to something like:

#include "image.h"

void print_op(imageop_t *imop)
{
   fprintf(stderr, "\n\n");
   fprintf(stderr, "op index      %d\n",
                    imop->opcode);
   fprintf(stderr, "in0:          %s\n",
                    imop->in0);
   fprintf(stderr, "in1:          %s\n",
                    imop->in1);
   fprintf(stderr, "out:          %s\n",
                    imop->out);
   fprintf(stderr, "dims:         %d %d\n",
                    imop->dims[0],
                    imop->dims[1]);
   fprintf(stderr, "factor:       %.3lf\n",
                    imop->factor);
}

void run_op(imageop_t *imop)
{
   switch (imop->code)
   {
   case 0:
       mirror_ppm_image(imop);
       break;
//   -- etc --

   }
}

int main()
{

   imageop_t imop;

   memset(&imop, 0, sizeof(imop));

   while (parser(&imop) == 0)
   {
      print_op(&imop);
      run_op(&imop);
      memset(&imop, 0, sizeof(imop));
   }
   return(0);
}

Step (3) change your existing image processing interfaces.

void mirror_ppm_image(imageop_t *imop)
{

/* Declare image_t structures for input and output images */

/* Initialize image_t structures using imop_t data */

/* Figure out a way to pass imop_t data (such as factor */
/* through to pixel processor functions                 */



}
