imagecopyresampled green color only

Hi to every one and yes, me again,

I done a working script, would you believe?

But although the original image has lot of red, the resampled image is
green only.
-----------------
$inImg = "a.jpg";

$max_width = 200;
$max_height = 150;

$size = GetImageSize($inImg);
$width = $size[0];
$height = $size[1];

$x_ratio = $max_width / $width;
$y_ratio = $max_height / $height;

if ( ($width <= $max_width) && ($height <= $max_height) ) {
$tn_width = $width;
$tn_height = $height;
}
else if (($x_ratio * $height) < $max_height) {
$tn_height = ceil($x_ratio * $height);
$tn_width = $max_width;
}
else {
$tn_width = ceil($y_ratio * $width);
$tn_height = $max_height;
}

$src = ImageCreateFromJpeg($inImg);
$dst = ImageCreate($tn_width, $tn_height);

imagecopyresampled($dst, $src, 0, 0, 0, 0, $tn_width, $tn_height, $width,
$height);
ImageFilter($dst, IMG_FILTER_CONTRAST, -10);

//header("Content-type: image/jpg");
ImageJpeg($dst, "mini.jpg", 75);
ImageDestroy($src);
ImageDestroy($dst);
----------------------------
Thanks for your attention.

solved with this line:
$thumb = @imagecreatetruecolor ($tn_width, $tn_height) or die ("flux d'image
