Large tall images are saving rotated 90º

[robksawyer]

Images uploaded via iPhone are rotated automatically. Any idea how to fix this?

I found the following StackOverflow post (http://stackoverflow.com/questions/13971491/captured-photo-automatically-rotated-during-upload-in-ios-6-0-or-iphone), but I'm just curious if you've run across this.

Never ran into it myself, but the ExifTransformer will auto-rotate and fix orientation based on exif data.

[robksawyer]

Should I accept more exif data like 'orientation' via the metaColumns array in setup?

Like this?

'metaColumns' => array(
                    'name' => 'name',
                    'ext' => 'extension',
                    'type' => 'mimeType',
                    'size' => 'fileSize',
                    'width' => 'width',
                    'height' => 'height',
                    'orientation' => 'orientation'
                ),

Using the transformer is similar to the others: http://milesj.me/code/cakephp/uploader#transforming-images-resize-crop-etc There is also exif specific meta data: http://milesj.me/code/cakephp/uploader#saving-meta-data

To confirm, like so?

public $actsAs = array(
        'Containable',

                'minHeight' => 150,

I'm getting the following when uploading locally.

Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 9792 bytes) in /Users/robksawyer/Sites/com/curdcollective/app/Vendor/mjohnson/transit/src/Transit/Transformer/Image/RotateTransformer.php on line 56

Note: The image is pretty large. It's 1.8mb and 2448x3264. I'm just testing with the worst possible scenario that someone might upload.

[milesj]

With all those transforms and stuff going on, PHP can't handle that large of a file. You can try messing with ini settings and removing the memory/time limit.

[robksawyer]

Yeah, I figured that was the issue. I may just offload these transforms to one of the good ol' Heroku addons. That is, after I run exif.

[robksawyer]

Is there anyway to keep exif data during the resize like the following? It seems as if it gets removed during the resize, right?

array(
    'nameCallback' => 'transformName',
    'method' => 'resize',
    'width' => 1280,
    'overwrite' => true,
    'self' => true
),
array(
    'method' => 'exif',
    'self' => true
),

[milesj]

Modifying images automatically removes exif data, that's just how it works, nothing I'm doing.

[robksawyer]

Got it. Thanks.
