Hallöchen! I prepared a branch "perspective-correction" that contains an additional callback for perspective correction (PC) in Lensfun's modifier object.
I admit that PC is not an intrinsic lens error, but it is closely related and benefits from Lensfun's framework. In particular, PC along with TCA, distortion, and projection can be rectified in one process without an intermediate image. (Plan is to add affine transformations later, to be really complete.) Moreover, PC needs focal length and crop factor, and the proper ordering relatively to projection transform and scaling, all of which is conveniently offered by Lensfun. There is a new manual section on <http://wilson.bronger.org/lensfun/perspective-correction.html>. With git clone --branch perspective-correction \ git://git.code.sf.net/p/lensfun/code lensfun you can clone the code locally. I would be grateful for any feedback, especially whether the code compiles properly with non-GCC, and whether the test suite runs through on your hardware.
