I try to resize and rotate an image with PHP (GD) but when image rotate, it add a black border on right.
Exemple image (before resize & rotate):
Exemple image (after resize & rotate):
Here is my code :
$image = $_FILES["file"]["name"];
$uploadedfile = $_FILES['file']['tmp_name'];
if ($image) {
$filename = stripslashes($_FILES['file']['name']);
$i = strrpos($filename,".");
$l = strlen($filename) - $i;
$ext = substr($filename,$i+1,$l);
$extension = strtolower($ext);
if (($extension != "jpg") && ($extension != "jpeg")
&& ($extension != "png") && ($extension != "gif")) {
echo ' Unknown Image extension ';
$errors=1;
}
else {
$size=filesize($_FILES['file']['tmp_name']);
if($extension=="jpg" || $extension=="jpeg" ) {
$uploadedfile = $_FILES['file']['tmp_name'];
$src = imagecreatefromjpeg($uploadedfile);
}
else if($extension=="png") {
$uploadedfile = $_FILES['file']['tmp_name'];
$src = imagecreatefrompng($uploadedfile);
}
else {
$src = imagecreatefromgif($uploadedfile);
}
$max_width = 175;
$max_height = 100;
$size=GetImageSize($uploadedfile);
$width_ratio = ($size[0] / $max_width);
$height_ratio = ($size[1] / $max_height);
if($width_ratio >=$height_ratio)
{
$ratio = $width_ratio;
}
else
{
$ratio = $height_ratio;
}
$new_width = ($size[0] / $ratio);
$new_height = ($size[1] / $ratio);
$tmp=imagecreatetruecolor($new_width,$new_height);
if(function_exists("exif_read_data")){
$exif = @exif_read_data($uploadedfile);
$rotateImg = imagerotate($src,0,0);
if(!empty($exif['Orientation'])) {
switch($exif['Orientation']) {
case 8:
$rotateImg = imagerotate($src,90,0);
break;
case 3:
$rotateImg = imagerotate($src,180,0);
break;
case 6:
$rotateImg = imagerotate($src,-90,0);
break;
}
}
}
imagecopyresampled($tmp,$rotateImg,0,0,0,0,($new_width-1),($new_height-1),$size[0],$size[1]);
$filename = sha1(basename( $_FILES['file']['name']));
$path = dirname(__FILE__)."/../files/pictures/".$filename;
imagejpeg($tmp,$path,100);
imagedestroy($src);
imagedestroy($rotateImg);
imagedestroy($tmp);
}
}
I tried some modification like the answers of this posts : - A border appears when rotating image with gd + php - PHP - Rotate image with GD gives black borders - Why when i rotate the image black borders appear? PHP GD
But nothing work.
Please guys helps me.
Thanks you
