How do I fill white background while resize image

Question

Current background is black. How to change the color to be white?

    #assuming the mime type is correct
    switch ($imgtype) {
        case \'image/jp

This is working for me. Although it logically seems like it should fill the whole image with the $bgcolor, it only fills the parts that are "behind" the resampled image.

imagecopyresampled($resized_image, $original_image, $xoffset, $yoffset, 0, 0, $new_width, $new_height, $orig_width, $orig_height);
$bgcolor = imagecolorallocate($resized_image, $red, $green, $blue);
imagefill($resized_image, 0, 0, $bgcolor);
