I'm currently trying to reproduce a PNG in Laravel as a response which is only presented to me as a data type resource.
And although I read the textures of a Minecraft skin and want to render the head of the player, I can't get the content to be recognized as PNG. If I want to display the image as a response via Laravel he always complains about the type and if I let it be displayed with imagepng it is not available as a real mimetype in the browser.
Code below

Head Method:

public static function head($rawSkin, $scale = 1, $vertRot = 0, $horRot = 0, $helmet = true)
 imagesavealpha($rawSkin, true);
 //we don't need create new **transparent** image because we use the full image size
 $canvas = imagecreatetruecolor(self::HEAD_SIZE * $scale, self::HEAD_SIZE * $scale);
 imagecopyresampled($canvas, $rawSkin, 0 * $scale, 0 * $scale, 8, 8
 , self::HEAD_SIZE * $scale, self::HEAD_SIZE * $scale, 8, 8);
 return $canvas;
 

Skinload Method:

 private function getImage($uuid)
 $result = file_get_contents("https://sessionserver.mojang.com/session/minecraft/profile/".$uuid);
 $result = json_decode($result);
 $textures = $result->properties[0]->value;
 $textures = json_decode(base64_decode($textures));
 return imagecreatefrompng($textures->textures->SKIN->url);
 

Response Method:

function renderHeadByUUID(Request $request)
 if(isset($request->uuid))
 header("Content-type: image/png");
 imagepng(MinecraftSkins::head($this->getImage($request->uuid)));
