Best Lossless Rotation Software

Can anyone recommend software that doesn't reduce quality when rotating images?

Thanks

Re: Best Lossless Rotation Software

Assuming you are rotating 90 or 180 Degrees, you should see no loss of quality at all.

As far as I know, and I'm not a windows user. XP and Vista will do this for you within explorer.

If you want more arbitrary rotation, you'll need a pixel editor such as Photoshop.

Are you sure your not confusing a picture taken in portrait mode, when shown on a screen is of times presented in landscape mode and when you rotate by 90 it will look smaller but there is no loss in quality!

Re: Best Lossless Rotation Software

Yes, I am only talking about rotating 90 or 180 degrees, but I seem to remember the first time i did it a warning came up that said there would a loss of quality and it is that which I wanted to avoid.

Is this not the case?

Re: Best Lossless Rotation Software

You are correct, I have seen this message many times in Windows Picture and Fax viewer.

I don't think it's a problem in photo editing software.

Re: Best Lossless Rotation Software

Okay, so the key is using something like Photoshop to rotate rather than Windows. I have used Vista's Windows Photo Gallery in the past, are you saying that it will degrade the quality?

Good read - even before I opened it I bet myself that IrfanView would be one of the recommended s/w - for what it does it works really well, and for free. (btw I am not in any way associated with Irfanview - just a happy user).

Re: Best Lossless Rotation Software

Paint anyone?
GIMP is free as its open source... pretty good if you know how to use it.
