Autopano vs DxO ViewPoint

Just stumbled upon DxO ViewPoint on another forum (http://www.dxo.com/intl/photography/dxo-viewpoint), which seems to be tailored towards lens and perspective corrections. Made me wonder, how AP compares to DxO in this regard? Have never tried this, but could you perform the corrections that DxO does also in AP (on a single image, not a pano)?
Thanks,

I don't think so.

No,you should not.....so that means maybe you could (AFAIK) but why would you. If you were to shoot the Arc de Triomph using APP you would use 10 x 7 foto's (or something like that, the sky is the limit).....then you could put the lines straight. Keystoning is putting the lines straight in a single image using a completely different algoritm (in fact you can sort of keystone in Gimp if you wanted using it's perspective correction tool). But real keystoning depends on the lensparameters and the angle of vision. It calculates the lines and uses the known perspective distortions of the lens to find the upward tilt of the lens and then correct the lensdistortions accordingly.

Now Klaus Esser will have a different opinion to this I'm sure.

Thanks, very informative.
Upon further reading on the DxO website, I found out out that they don't support the X-Trans sensor in my Fujis, though.

X-Trans sensors are a bit of pest to support....even ACR has it's problems with them (acording to the grapevine)....best to use the RAW converter supplied and rework to tiff 16 bit and then you can do your keystoning anywere you like....as this page shows....see last part about the integration into lightroom.

I guess this means that you can convert using ACR and then use the plugin in Lightroom.
