Libpng is a library for use either with a compiled binary that requires it, or it could be required at compilation time also.
A typical code snippet requiring is shown below:
#include <png.h>
...
int writeImage(char* filename, int width, int height, float *buffer, char* title)
{
int code = 0;
FILE *fp = NULL;
png_structp png_ptr = NULL;
png_infop info_ptr = NULL;
png_bytep row = NULL;

gcc -o makePNG makePNG.c -lm -lpng
