GD/Imagick 不保存我的圖像 (GD/Imagick doesn't save my image)
I want to send an image from android and save it trought a php code in my server. Because I need to protect my server I need to reprocess the image so I have to use GD or Imagick. Image is sent encoded in base64. In the php file is decoded and if I use:
$img=base64_decode($img);
$file = fopen('test.jpg', 'wb');
fwrite($file, $img);
fclose($file);
image is saved in the server. If I use Imagick or GD my image isn't saved and the php files returns nothing, even if I insert an echo after it. Any help? In GD I was using:
$img=base64_decode($img);
$imageinfo = getimagesize($img);
if($imageinfo['mime'] == 'image/gif'{
$img = @imagecreatefromjpeg($img);
imagejpeg($img, ""testt.jpg", 80);
}
and in Imagick:
$img=base64_decode($img);
$img = imagick($img); //neither if I use a path of an image saved in my server
//works
$mime = mime_content_type($img);
switch ($mime):
case 'image/jpeg':
$ext = '.jpg';
break;
endswitch;
$img‑>stripImage();
$img‑>writeImage(""testt".$ext);
$img‑>clear();
$img‑>destroy();

方法 1:
imagick only works on files, you can't give a handle to it unfortunately, so:
$img=base64_decode($img);
$filename = tempnam(sys_get_temp_dir(), 'tempimage_');
$file = fopen($filename, 'wb');
fwrite($file, $img);
fclose($file);
$img = imagick($filename);
$mime = mime_content_type($img);
switch ($mime):
case 'image/jpeg':
$ext = '.jpg';
break;
endswitch;
$img‑>stripImage();
$img‑>writeImage("testt".$ext);
$img‑>clear();
$img‑>destroy();
This, in theory, should work.
