Automatic image rotation from mobile Recently I had a use case when I needed to automatically rotate uploaded pictures according to the sensor data embedded in the image (think iPhone, iPad, Android phones, DSLR cameras, etc) I ended up using PHP Imageworkshop (http://phpimageworkshop.com/documentation.html) for all my image processing needs so …

upload.php

//retrieve the image
$image = Input::file('image');

// initialize imageworkshop layer
$layer = PHPImageWorkshop\ImageWorkshop::initFromPath($image['tmp_name']);

if (File::is('jpg', $image['tmp_name']))
{
    $exif = exif_read_data($image['tmp_name']);

    if(isset($exif['Orientation'])&& $exif['Orientation'] == '6'){
       $layer->rotate(90);
    }

    if(isset($exif['Orientation'])&& $exif['Orientation'] == '3'){
    	 $layer->rotate(180);
    }
}

// 2. Where do you want to store it?
$dirPath = path('public').'/uploads/temp/';

// 3. Give it a name
$filename = 'avatar.jpg';

// 4. If needed, do you want to create new folders?
$createFolders = true;

// 5. The backgroundcolor. Use transparent, only for PNG (otherwise it will be white if set null)
$backgroundColor = null; 

// 6. Useless for GIF, usefull for PNG and JPEG (0 to 100%)
$imageQuality = 95; 

// 7. Save image
$layer->save($dirPath, $filename, $createFolders, $backgroundColor, $imageQuality);
