Drupal 7，iPhone的图像方向搞砸了 - 没有exif信息

问题描述：

因此，我已经失去了两天的思想。我必须建立在Drupal的7Drupal 7，iPhone的图像方向搞砸了 - 没有exif信息

我有这个问题一个网站，当我的网站用户上传从iPhone或iPad的图像（均通过的CKEditor和帐户通过表单上传个人资料图片）图像最终被颠倒。

我已经写了独立的PHP来读取exif数据的图像和检测到问题时，我注意到一个奇怪的问题。图像在不在drupal中时有exif信息，看起来他们一旦上传到drupal就会失去exif信息。

我使用该代码来读取EXIF信息

$full_filename ='image.jpg'; 
$exif = exif_read_data($full_filename); 

print "<pre>"; 
    print_r($exif); 
print "<pre>";

这是与未上传到DRUPAL

图像读出的结果，这是从上传到drupal的图像信息

Array

    [FileName] => image3.jpg 
    [FileDateTime] => 1372355645 
    [FileSize] => 75670 
    [FileType] => 2

    [COMPUTED] => Array 
     (
      [html] => width="1024" height="765" 
      [Height] => 765 
      [Width] => 1024 
      [IsColor] => 1 
     ) 

    [COMMENT] => Array 
     (
      [0] => CREATOR: gd-jpeg v1.0 (using IJG JPEG v62), quality = 75 

     ) 

)

是否有可能drupal与此有关。 GD工具包？

我试过使用imagecache自动旋转，它旋转的图像没有从iPhone上传，但没有运气与iPad或iPhone的。

我不确定如何去做这件事。欢迎所有帮助。

答

你没看到东西。

iPhone/Pad在发送图像时剥离EXIF信息。

Image upload from iphone strips exif data

的EXIF自定义模块可能会有所帮助。

https://drupal.org/project/exif_custom

所以可能ImageCache操作

https://drupal.org/project/imagecache_actions
