# NAME

Image::JpegTran::AutoRotate - Losslessly fix JPEG orientation

# SYNOPSIS

    use Image::JpegTran::AutoRotate; # auto-exports auto_rotate

    auto_rotate('file.jpg'); # rotates in-place (via a temporary file)
    auto_rotate('from.jpg' => 'to.jpg'); # writes to another file

# DESCRIPTION

Transforms JPEG files so that orientation becomes 1.

This is the same operation as `exifautotran`, but with no dependencies on
command-line programs; instead, we use the excellent [Image::JpegTran](http://search.cpan.org/perldoc?Image::JpegTran) and
[Image::ExifTool](http://search.cpan.org/perldoc?Image::ExifTool) CPAN modules.
