Croppa not rotating images on crop

[LasseHaslev]

I cannot make croppa auto rotate images in my laravel application. I use Homestead -v 2.1.4 and when i run the exif_imagetype function i get a valid callback, so i think exif should be installed.

Can you post the image that's not rotating for you?

[LasseHaslev]

I use iPhone 4s.
Seems like the image is not rotating here either. :)

I also have this issue, images are not being auto-rotated based on the EXIF data. Here is the output from ExifTool for a sample image that is not working for me:

Ok, I see the problem. The exif_read_data function needs to read from the filesystem. But in Croppa 4, with the switch to supporting Flysystem, I'm interacting with raw image data throughout. I don't necessarily have a path to a file, like if the file was on a remote filesystem.

Maybe I can do something like this: http://stackoverflow.com/a/5465741/59160. Or I need to save the image locally, like to a /tmp directory, while doing the image manipulations. Which is what I'll need to do if I DO switch to Intervention ( #110 ), which has the same issue:

• http://image.intervention.io/api/orientate
• EXIF Orientation value Intervention/image#336

@weotch Any news on this issue? I just got this issue and don't really know what to do with it :/
Does it make sense to rotate the image right at upload so that the information is not really needed afterwards? What do you think?
Or are you planning on changing this any time soon?

[weotch]

I don't see myself working on it myself right now, but I'd take a PR. Or, like you suggest, you could apply the EXIF rotations immediately on file upload independent of Croppa.

Croppa uses the weotch fork of PHPThumb, which is no longer accepting pull requests for the 1.0 branch. I came up with a workaround, but for all I know I'm doing something horrible or there are scenarios I'm not aware of in which this wouldn't be good to do, so use this workaround with caution.

First, change the ThumbBase class' isDataStream property from protected to public.

Second, replace this line from the JpgImageRotation class' rotateJpg method:

Old:

$exif = @exif_read_data($this->parentInstance->getFilename());

New:

if ($this->parentInstance->isDataStream) {
    $stream = fopen('php://temp', 'r+');
    fwrite($stream, $this->parentInstance->getFilename());
    rewind($stream);
    $exif = @exif_read_data($stream);
}
else {
    $exif = @exif_read_data($this->parentInstance->getFilename());
}

I experienced this same issue, and have prepared a pull request to resolve it by copying the remote file to a temporary disk if desired.
