Can someone tell me how to get the liquid rescale plugin to expand into transparent areas? I have a panorama with stepped transparent areas of sky in one part of the image. I would like to expand the sky into the transparent areas, but I can't get it to work. The image as a whole does not need to be resized.

I started by painting a preserve mask over everything but sky, but the result looks like nothing was done. I then tried using a rigidity mask and no preserve mask, with the same result.

Is it even possible to use LqR to do this? Is there a better way?

Thanks for any insights,

Gary

Hello Gary
I don't know about LqR have not used it

from what I understand from your description about the transparent areas , hope I'm correct with this - trying to visualize hmm what you are doing , I know this will work there's a plugin Gimp Resynthesizer and it works by healing the transparent areas or selection areas and it's easy to work this plugin , someone who gives a good help page is

look on his site many useful articles might be one for LqR never know if you don't go look.

Hope this help.

there is this line

Note that, depending on the picture and the desired result, other techniques, such as using the Resynthesizer GIMP plugin, can yield better results. Combining more than one technique is a good idea, too. from

This an be tricky depending on the extent of the area that needs to be filled.

I've often found other problems - particularly if there's a large gradient of varying brightness across a sky (this is exacerbated when the images are shot late in the evening or early in the day - but can be just as troublesome on a clear day as well).

In the past I've had luck with cloning large sections of the sky or just copy/pasting a big region to where I need it and blending it by hand if necessary. I'm not at a GIMP machine at the moment to demonstrate, but if you post an example image over on the pixls.us forums I'd be happy to maybe record a quick video of attempting a repair.

Resynthesizer and G'MIC inpainting often work best when there's texture that needs to be synthesized to match it's surroundings, but might not do as good a job if it's a big area of gradient sky.

Thanks for the reply.
I've tried resynthesizer and the results are not very good with sky. I've tried both resynthesizing transparent areas and resynthesizing between a pasted section at the top and the existing sky at the bottom.

Sky seems to be particularly difficult to resynthesize in a manner which complements the existing sky in the image.

None of the articles I have found on LqR show its use for filling transparent areas without resizing.

Hello Gary
Talking to a photographer that works and lives nearby , we often talk about best ways to get the best out of images , his suggestion (unless you have already tried this) copy/paste a much larger than you need selection , make it a new layer under main image , move that bottom layer left/right/up/down until it sort of looks umm ok then with the erase tool set at a large size with opacity turned down down , I think he means to have it blend in (as much as you can) definitely I was told without using the smudge tool , also mentioned that using a non standard brush eg smoke/cloud/splatter type brushes set to large size could also help .

My suggestion is keep experimenting and enjoy and that's what art is all about... you never know when the next - "Happy Accidents In Art" will happen

Hope it Helps & Good Luck
