imagefill() turns rest of the area black

I'm using imagefill() for changing the background color if an image.But while doing so the other areas which are not to be affected, change its color to black.

$image = imagecreatefrompng("sample.png");
$background = imagecolorallocate($image, 255, 0,0);
imagefill($image, 0,0, $background);
header("content-type: image/png");
imagepng($image,"sample.png");

This is my code.Can anyone tell me how this is happening ?

Try setting the blending mode and saving the alpha

imagealphablending($image, false);
imagesavealpha($image, true);
