Newb:Save image to a file:C++
Date: Sat, 28 Feb 2009 08:54:04 -0800 (PST)
Hi,
I'm trying to grab an image from a site and save it to a file. I can get the image file that I wanted but I can't view the result file, I noticed that the result file has a bit different file size from the original file and If I open the images file using text-editor, its only difference is at the beginning of the file (has an extra newline and maybe another data not displayed).
Am I doing it wrong?
//code
#include <iostream>
#include <curl/curl.h>
#include <stdio.h>
using namespace std;
int main(){
CURL *image;
CURLcode imgresult;
FILE *fp;
char *url = "http://www.google.co.id/intl/en_com/images/logo_plain.png";
image = curl_easy_init();
if( image ){
// Open file
fp = fopen("google.png", "w");
if( fp == NULL ) cout << "File cannot be opened";
curl_easy_setopt(image, CURLOPT_WRITEFUNCTION, NULL);
curl_easy_setopt(image, CURLOPT_WRITEDATA, fp);
curl_easy_setopt(image, CURLOPT_URL, url);
// Grab image
imgresult = curl_easy_perform(image);
if( imgresult ){
cout << "Cannot grab the image!\n";
}
}
// Clean up the resources
curl_easy_cleanup(image);
// Close the file
fclose(fp);
return 0;
}
Thank you
