PHP Remove black bar from image - php

Question

I have a script that crops and rotates an image.
But i end up with a black bar in my image:
http://prntscr.com/r9l1w5 (screenshot)
I found a script on the internet, that is able to remove black bars on images. But i am unable to make it work together on 1 page.
(view-image.php) My script:
<?php
$filenamegetter = $_GET['imgid'];
$degree = 0;
// File and rotation
$filename = 'img/' . $filenamegetter . '';
$degrees = $degree;
$percent = 0.30;
// Content type
header('Content-type: image/jpeg');
// Get new sizes
list($width, $height) = getimagesize($filename);
if ($width > "1000") {
$newwidth = $width * $percent;
$newheight = $height * $percent;
} else {
$newwidth = $width;
$newheight = $height;
}
// Load
$thumb = imagecreatetruecolor($newwidth, $newheight);
$source = imagecreatefromjpeg($filename);
// Rotate
$rotate = imagerotate($source, $degrees, 0);
imagecopyresized($thumb, $rotate, 0, 0, 0, 0, $newwidth, $newheight, $width, $height);
imagejpeg($thumb);
// Free the memory
imagedestroy($source);
imagedestroy($thumb);
?>
The anti black bar script i wish it works together with:
<?php
$image_path = "image.jpg";
$jpg = imagecreatefromjpeg($image_path);
$black = array("red" => 0, "green" => 0, "blue" => 0, "alpha" => 0);
$removeLeft = 0;
for($x = 0; $x < imagesx($jpg); $x++) {
for($y = 0; $y < imagesy($jpg); $y++) {
if(imagecolorsforindex($jpg, imagecolorat($jpg, $x, $y)) != $black){
break 2;
}
}
$removeLeft += 1;
}
$removeRight = 0;
for($x = imagesx($jpg)-1; $x > 0; $x--) {
for($y = 0; $y < imagesy($jpg); $y++) {
if(imagecolorsforindex($jpg, imagecolorat($jpg, $x, $y)) != $black){
break 2;
}
}
$removeRight += 1;
}
$removeTop = 0;
for($y = 0; $y < imagesy($jpg); $y++) {
for($x = 0; $x < imagesx($jpg); $x++) {
if(imagecolorsforindex($jpg, imagecolorat($jpg, $x, $y)) != $black){
break 2;
}
}
$removeTop += 1;
}
$removeBottom = 0;
for($y = imagesy($jpg)-1; $y > 0; $y--) {
for($x = 0; $x < imagesx($jpg); $x++) {
if(imagecolorsforindex($jpg, imagecolorat($jpg, $x, $y)) != $black){
break 2;
}
}
$removeBottom += 1;
}
$cropped = imagecreatetruecolor(imagesx($jpg) - ($removeLeft + $removeRight), imagesy($jpg) - ($removeTop + $removeBottom));
imagecopy($cropped, $jpg, 0, 0, $removeLeft, $removeTop, imagesx($cropped), imagesy($cropped));
header("Content-type: image/jpeg");
imagejpeg($cropped); //change to `imagejpeg($cropped, $image_path);` to save
imagedestroy($cropped);
imagedestroy($jpg);
I'd like to know how i can implent the anti black bar script in my script. I tried multiple ways but i end up with a empty page.

For anyone having problems with imagecopyresampled or imagerotate with black bars on background, I have found a code example here:
There are a lot of factors but for me the problem was the new size after rotating the image.
https://qna.habr.com/q/646622#answer_1417035
// get image sizes (X,Y)
$wx = imagesx($imageW);
$wy = imagesy($imageW);
// create a new image from the sizes on transparent canvas
$new = imagecreatetruecolor($wx, $wy);
$transparent = imagecolorallocatealpha($new, 0, 0, 0, 127);
$rotate = imagerotate($imageW, 280, $transparent);
imagealphablending($rotate, true);
imagesavealpha($rotate, true);
// get the newest image X and Y
$ix = imagesx($rotate);
$iy = imagesy($rotate);
//copy the image to the canvas
imagecopyresampled($destImg, $rotate, 940, 2050, 0, 0, $ix, $iy, $ix, $iy);
