PHP exif_read_data IFD大小非法 [英] PHP exif_read_data Illegal IFD size

问题描述

我正在开发一个应用程序，该应用程序可以修复从AWS存储桶下载的jpeg文件的方向(如果存在).

I'm working on an application where I fix orientation (if it is present) of jpeg files downloaded from an AWS bucket.

此处您可以验证该图像是否具有exif旋转部分.

Here you can verify that this image has exif Rotation section.

我通过下载图像

file_put_contents('/local/path/to/file', file_get_contents('/path/to/url/image'));

然后，我尝试通过 Gregwar图像库修正方向.

And after I try to fix orientation through the Gregwar Image library.

Image::open($path)->fixOrientation()->save($dest, $type, $quality);

我尝试了几张图像，但我总是收到消息

I tried with several images and I always receive the message

Warning: exif_read_data('/local/path/to/file'): Illegal IFD size

我认为这是与如何检索图像有关的问题，但是我也尝试了cUrl和fopen的相同结果.

I thought that was a problem related with how I retrieve the images, but I tried also with cUrl and fopen with the same result.

有人有什么建议吗?

推荐答案

您可以在忽略警告之前使用"@":@Image::open($path)->fixOrientation()->save($dest, $type, $quality);

You can use a "@" before to ignore warnings: @Image::open($path)->fixOrientation()->save($dest, $type, $quality);

很多人通过互联网对此抱怨.可能是一些带有错误的exif数据.如果您的操作按照您想要的方式进行，只需对其进行记录并继续.

That is a lot of people complaining about this over the internet. Probably some exif data with error. If you operation is working the way you want, just document it and move on.
