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 and Image::ExifTool CPAN modules.
