perspective correction

Posting rules: It shouldn't need saying, but... play nice. Please keep your discussions civil. You can disagree, just don't be disagreeable. And, of course, all of the usual stuff like no spamming. Tex adds: I'll be rigorously enforcing this as we go along. We're probably going to be a small community in a little lifeboat, so we can't have members at each others' throats. This is for the sake of the project as a whole. So when you post, pretend you're speaking in person with your very wealthy auntie who has always treated you wonderfully and currently lists you prominently in her will. I won't be tossing anyone out of the forums because we are all in this together (except spammers: immediate membership cancelation), but I'll delete suspect posts right away.

perspective correction

Hi everyone,

a big thank you to all the programmers and other supporters behind lz. I know some automatic, lens-dependent correction is on your todo list, but I would suggest something else. If you check Affinity Photo you can see a very simple yet effective manual correction, 3 (main) parameters: distortion (barrel vs  pincusshion), horizontal and vertical (both perspective). I've been using this with very good results and in almost no time on a couple of lenses and it requires no lens database to be maintained. Moreover, as you already have the code to rotate (thus transform) the image I not see what could be a problem to add code for this three parameters (which are also transformations). I hope not too sound to arrogant, but with 25+ years programming on my belt I vaguly guess this is no big change. Of course I dont know the codebase and I can only guess with what you have to deal :) Best regards, Peter
