Tutorial: Rotating Skewed Images Accurately
This tutorial is for the benefit of members who routinely ask how to correct skewed images. Enjoy!

To confirm that the image is indeed correctly aligned, I would suggest turning on the grid ie View > Show Grid.
This is especially so if you want to correct converging or diverging verticals as well, using Distort.

This link will be useful.

This is great!
Thus far, I've always been using "agar-ation"!
Very much thanks!
How about a tutorial on correcting converging or diverging verticals? I'm quite sure many users (myself inclusive) will benefit from it.
Have another question which I hope someone can help.
After doing a rotation, let's say I wanna crop the picture to a particular size of exactly x times y pixels, how do I actually go about doing it? At the moment, what I do is "agar-ation" again, just select, resize down and hope for the best...
Thank you very much!

Turn on rulers, Ctrl-' and place a ruler along all vertical lines and then Ctrl-A, Ctrl-T and drag corner nodes.

u can actually ROTATE and CROP at the same time. But u need a steady hand/optical mouse and keyboard to do well.
