Image center square image using imagecopyresampled

I am trying to create 2 cropped thumbnails (60x60 and 150x150) from a normal sized image. Everything works fine except crop, which doesn't work. This part creates a thumbnail with a black line on the right side, like this:

.............
.         ...
.         ...
.         ...
.............

Scaling works great because the final sketches have the correct heights of 60 and 150 (working with the landscape image as the original), but they still go out of the landscape.

What I have:

list($thumb_width, $thumb_height) = getimagesize($thumb_target);
if ($thumb_width > $thumb_height) { // landscape
    $thumb1_new_height = 60;
    $thumb1_new_width = floor( $thumb_width * ( $thumb1_new_height / $thumb_height ));
    $thumb1_crop_x = ceil(($thumb_width - $thumb_height) / 2);
    $thumb1_crop_y = 0;
    $thumb2_new_height = 150;
    $thumb2_new_width = floor( $thumb_width * ( $thumb2_new_height / $thumb_height ));
    $thumb2_crop_x = ceil(($thumb_width - $thumb_height) / 2);
    $thumb2_crop_y = 0;
}
else if ($thumb_width < $thumb_height){ // portrait
    $thumb1_new_width = 60;
    $thumb1_new_height = floor( $thumb_height * ( $thumb1_new_width / $thumb_width ));
    $thumb1_crop_x = 0;
    $thumb1_crop_y = ceil(($thumb_height - $thumb_width) / 2);
    $thumb2_new_width = 150;
    $thumb2_new_height = floor( $thumb_height * ( $thumb2_new_width / $thumb_width ));
    $thumb2_crop_x = 0;
    $thumb2_crop_y = ceil(($thumb_height - $thumb_width) / 2);
} else { // square
    $thumb1_new_width = 60;
    $thumb1_new_height = 60;
    $thumb1_crop_x = 0;
    $thumb1_crop_y = 0;
    $thumb2_new_width = 150;
    $thumb2_new_height = 150;
    $thumb2_crop_x = 0;
    $thumb2_crop_y = 0;
}
$thumb1_tmp_img = imagecreatetruecolor($thumb1_new_width,$thumb1_new_height);
$thumb2_tmp_img = imagecreatetruecolor($thumb2_new_width,$thumb2_new_height);
imagecopyresampled($thumb1_tmp_img, $thumb_img, 0, 0, $thumb1_crop_x, $thumb1_crop_y, $thumb1_new_width, $thumb1_new_height, $thumb_width, $thumb_height);
imagecopyresampled($thumb2_tmp_img, $thumb_img, 0, 0, $thumb2_crop_x, $thumb2_crop_y, $thumb2_new_width, $thumb2_new_height, $thumb_width, $thumb_height);
