History

#1 Updated by Rick Gabriel almost 6 years ago

I just learned that "crop and rotate" can do this, but it's effect is limited. Perhaps it could be enhanced to allow more flexible perspective correction or partial correction. In any case, I'm sure any such enhancement is a low priority.

#2 Updated by Jérémy Rosen almost 6 years ago

I don't know these, what do they do that the keystone correction in crop and rotate doesn't do ?

#3 Updated by Simon Spannagel almost 6 years ago

...and for more complex lens distortion correction we have the lenscorrection module with the lensfun database behind it.

#4 Updated by Rick Gabriel almost 6 years ago

zPerspector and others just offer a little more flexibility. For example, you can correct one corner of an image without affecting the others, you can bring a corner and one side in while leaving the rest alone, you can mirror an effect to the opposite part of an image, etc. The keystone correction and lensfun do account for the majority of corrections one would want to do, but it's possible to have some more flexibility here. I just wanted to get this into your system to keep it on the radar, but I agree it's very low priority.
