Brilliant works like a charm! Thanks man!!.
I am trying to add a 360 degree bearing plotter for the Navigation Map like this

'
This is one nice feature I miss from SH3, cause it gives you direct bearing at a glance etc. Now, when I open this in the "DXTBmp" and look at the Alpha channel I see the Bearing Plotter (this data is from the "Bearings Mod by Jase") , tried to save it as dds but don't see the graphics in the game. Could be that I am doing this totally wrong, any hint would be mush appreciated. As i am at work at the mo I can not really try stuff, but I fiddled a bit with it this morning and no go.
