How to detect orentation of an image inan action

I want to write an action that works on and can detect if the image is landscape or portrait.

The Break down is

If portrait then set the image height to 400px
If portrait then set the image width to 400px

Set the canvas size = 410 X 410

Then there is other processing to be done…
The rest I can do no Problems

File>Automate>Fit_Image
or:
Use Image Processor from Bridge to do the same thing but with more options.
