I`m using this addon to load and display gif files : https://github.com/Geistyp/ofxGif

but when i load this gif image, the image seems broken

^ this is original gif file

^ and when i debug this code, gif image are displayed like this

include "ofApp.h"

int index = 0;

//--------------------------------------------------------------
void ofApp::setup(){
gifloader.load("view.gif");
}

//--------------------------------------------------------------
void ofApp::update(){
if (ofGetElapsedTimeMillis() % 2)
{
index++;
if (index > gifloader.pages.size()-1) index = 0;
}
}

//--------------------------------------------------------------
void ofApp::draw(){
ofBackground(150,200,60);
ofSetColor(255, 255, 255, 255);
ofImage img = gifloader.pages[index];
ofPixels pix = img.getPixels();

ofPixels rpix = pix.getChannel(0);
ofPixels gpix = pix.getChannel(1);
ofPixels bpix = pix.getChannel(2);

pix.setChannel(0, rpix);
pix.setChannel(1, gpix);
pix.setChannel(2, bpix);

img.setFromPixels(pix);

img.draw(100, 100);
}
