对齐水印与PHP左上角而不是右下角

Question

我尝试了很多方法来将水印图像的坐标改变到左上角，但我无法理解哪些变量定义了顶部，左侧，右侧和底部角落。

我希望你能帮助

//Source folder where all images are placed 
$source="source"; 

//Destination folder where all images with watermark will be copied 
$destination="destination"; 

//Creating an image object of watermark image 
$watermark=imagecreatefrompng("watermark.png"); 

//Margin of watermark from right and bottom of the main image 
$margin_right=10; 
$margin_bottom=10; 

//Height ($sy) and Width ($sx) of watermark image 
$sx=imagesx($watermark); 
$sy=imagesy($watermark); 

//Get list of images in source folder 
$images=array_diff(scandir($source), array('..', '.')); 

foreach($images as $image){ 
    //Create image object of main image 
    $img=imagecreatefromjpeg($source.'/'.$image); 

    //Copying watermark image into the main image 
    imagecopy($img, $watermark, imagesx($img) - $sx - $margin_right, imagesy($img) - $sy - $margin_bottom, 0, 0, $sx, $sy); 

    //Saving the merged image into the destination folder 
    imagejpeg($img, $destination.'/'.$image,100); 

    //Destroying the main image object 
    imagedestroy($img); 
} 

//Destroying watermark image object 
imagedestroy($watermark); 

?>

那么它在你的代码！

//Margin of watermark from right and bottom of the main image 
$margin_right=10; 
$margin_bottom=10; 

我不知道如何脚本的工作，但您可以添加：

$margin_left=10; 
$margin_top=10; 

，并删除：

$margin_right=10; 
$margin_bottom=10; 

它并不真正涉及到PHP！它看起来像CSS配置！
