[OT] Irfanview autorotate

[solid]

Sorry fot OT, but i know plenty of users here use irfanview, and the irfanview forum is practically dead.

I need to autorotate jpg files from digicam, based on exif data. I know that is possible with Shift+J, than autorotate, but i need it from the command line.

There are only switches for left and right lossless rotate, but not for auto.

Is this possible, or it is a feature request?

I currently use Jexif and Jpegtran, but the downside is that jpegtran must be in /system (or other command path), so lookinf for a more elegant way.
