Salut, am gasit acest cod pe net


#include "stdafx.h"
#include <stdio.h>
#include <gd.h>
#include <gdfontg.h>

int main(int argc, char *argv[]) {
gdImagePtr img;
FILE *fp = {0};
int width, white, black;

width = white = black = 0;

if(argc != 3) {
fprintf(stderr, "Usage: pngtxt image.png 'Hello world.. !'\n");
return 1;
}

fp = fopen(argv[1], "wb");
if(fp == NULL) {
fprintf(stderr, "Error - fopen(%s)\n", argv[1]);
return 1;
}

width = strlen(argv[2]);

img = gdImageCreate(width * 10, 20);

white = gdImageColorAllocate(img, 255, 255, 255);
black = gdImageColorAllocate(img, 0, 0, 0);

gdImageString(img, gdFontGiant, 2, 1, argv[2], black);

gdImagePng(img, fp);

fclose(fp);
gdImageDestroy(img);

return 0;
}

Cand compilez, imi da
