This simple code flips the texture but it doesn't solve the purpose..
Code:
import viz
viz.go()
ar = viz.add('artoolkit.dle')
camera = ar.addWebCamera()
camera.background.setEuler([180,0,0])
camera.background.setPosition([640,0,0])
marker = camera.addMarker('ar/patt.worldviz',width = 1000)
logo = viz.add('logo.ive')
viz.link(marker,logo)
Marker positions miss match with the image if we go with this code.
