Write a C program that reads in a ppm image using command line arguments and then stores its pixel contents in a linked list of pixels. A header file, transform.h, is provided below, where you will use the two provided structs for declaring the linked list and the function prototypes parseHeader() to get the width and height of the ppm image, and getImage(), to send the width, height, and image pointer to get the pixel data and create the linked list.

transform.h

#include #include #include

// Linked list node typedef struct pixel { unsigned char r, g, b; struct pixel * next; }pixel_t;

typedef struct list { pixel_t * head; pixel_t * tail; } list_t;

void parseHeader( FILE *input, int *cols, int *rows ); void getImage( FILE *input, int rows, int cols, list_t * theImage );
