GIF almost empty

OK, sorry, no, that doesn't work either.
This is the issue:
I load a svg into the ctx canvas.

//load planet image
planet.ready = false;
planet.image = new Image();
planet.image.onload = function () {
planet.ready = true;
};

This is the code that initializes the drawing and draws the image into the canvas

//draw planet
    if (planet.ready)
    {
        ctx.drawImage(planet.image, planet.x-planet.r, planet.y-planet.r,planet.r*2,planet.r*2);
    }
    else
    {
    alert('Image not loaded');
    ctx.arc(planet.x,planet.y,planet.r,0,Math.PI*2);
    ctx.fill();
    }
    //trajectory drawing start
    ctx.strokeStyle="#FF0000";
    ctx.beginPath();
    ctx.moveTo(satellite.x,satellite.y);

At first my program doesn't load it I don't know why, so the svg isnt loaded into the canvas and the circle is drawn instead. In that case the gif recording works fine.
After a second if I hit my "reset" button the svg is loaded and everything is redrawn, with svg into the canvas. Then the gif recording fails.

Already tested and the issue isn't with the transformations or the lack of setSize.

Aaaand... I got the workoround and the possible problem. The scripts and the SVG are in a folder in the local disk. If you try to do a getImage on a canvas that has an image from a different domain, Chrome gives security error. Also, all local files (file://) are treated as external, so, getImage has that error. Jsgif has a getImage for the passed canvas context and is probably hitting that error. Problem is the whole procedure is in a try-catch block so we don't get to know what's going on.
A workaround is to run chrome.exe --allow-file-access-from-files

Maybe my pull request might be worth a try.

By default the sampling factor is 10 which means not all pixels serve as input for the neural net in NeuQuant.js. This way pixel colours can be lost. Setting it to 1 will ensure that the network is learning from every pixel
