stretching one angle of a picture

Postby IndoMK » Fri Oct 29, 2010 3:05 am

I think this is where this belongs...

I'm in the middle of a gimp project where I need to stretch an angle cut to straight without distorting the rest of the picture. So far I haven't been able to figure out how...

Ok, more explanation. I have a picture of a cathedral hallway, the perspective isn't exactly center, and I need both sides of the picture to be the same (lighting and etc). So I selected the left side, and remove from selection the portion of the ceiling that belonged to the other side. This left me with an angle across the top right corner of the picture. I duplicated the layer, flipped it horizontally, moved it to the right, and aligned it. But now I have a 'v' into the top of the picture. I need to take that angle, and stretch it to vertical so that the ceiling arches will match. But I can't distort the rest of the picture... Any ideas?

Oh, of course. Silly of me not to have done so before. I took two screenshots, one of the original image, and one of where I'm currently 'stuck'...

Mm, tried to attach it, was told that the file size is too big. It's a 17mb file... The only layers are the original image, the left and right halves, and a lightening overlay. Should I take any of those out to decrease the size?

Oh good idea! Except I can't remember my mediafire password... :P But dropbox works just as well I think. :) Here you are... http://dl.dropbox.com/u/8575541/Hope.zip

Looks like a case for resynthesizer .. but it will take a time with such a huge picture...
BTW:
G'MIC has got an "Anisotropic Filtering" filter, wich will reduce all the noise in your image. It's highly recommended to use ;)

Still some stuff that needs tweaking, I'll try to get around to it if you like this at all.

nice edit cyril, some stuff that could be fixed when you look close but solid overall. not to derail this topic or anything, (the first one i found you on), any word from the staff on if gt is eventually going back up? just curious, seems like a while now since it's been working.
