c.set( pixel[0], pixel[1], pixel[2] );

Actually without changing anything in the code the error occurs like 2 in 3 times, not every time.

I am on PC with visual studio. I am working with this tutorial : http://openframeworks.cc/ofBook/chapters/generativemesh.html and I started customize it by adding these lines in the void ofApp::draw()

    int numVerts = mesh.getNumVertices();

    for (int i = 0; i < numVerts; ++i) {

        ofVec3f vert = mesh.getVertex(i);

        int x = int(vert.x);
        int y = int(vert.y);

        ofColor couleur = image.getColor(x, y);
        ofSetColor(couleur);
        ofFill();

        ofDrawEllipse(vert.x, vert.y, 10, 10);

    }

The problem seems to be with the getColor function maybe

I am a beginner with openframeworks and visual studio

If you have any question or if I am not clear, ask me

Thanks
