Would DGALWARP be suitable?
It relies on PROJ.4, which does support Lambert Azimutal Equal Area... but which is the right command line?
I can't understand False Easting and False Northing.
That's a nice little app there I will have to play with that !
I was going to suggest using a Perl/Python script to do it instead but I guess you would need a lot of ancillary stuff to get the image in and out and the math to do it correctly.
Sorry I don't know about the params to drive that app though I will have a go and see what I come up with. Might be a while posting back tho - time seems to slip through my fingers of late.
Just throwing you these two links which might be useful.
