Is there a script or plugin for gimp that does the same thing as PS 'crop and straighten photos' to separate multiple photos from one scan?

I am trying to restore an old photo that includes a coffee can in the foreground.  I was able to find several donor images of the can I need.  These were rectangularized, flattened, and then stitched together to make a large flat version of the complete can.  The result isn't perfect, but should be fine for what I'm doing.

   


I then used the FILTERS->MAP->MAP OBJECT->Cylinder  filter to make a new 3D cylinder out of it that I could rotate into the proper orientation.  The problem, as pointed out by the arrows, is that several sections of the new cylinder are transparent.  The original flat image has no transparencies.


   

So what is going on here?  How do I make a cylinder with no random transparencies?

The tools-options and layers windows absolutely refuses to popup and show until I check single-window-mode.  Then everything shows up.  The only thing I can imagine is that Gimp imagines that they are off the my viewable display window.  I mean like when window gets to the 4000+ pixel on a 4K 3840width size.  But that's just a theory.  Another theory is that since I upgraded from 2point something, and I was using those windows, something got lost in the shuffle.  Actually it was less of an upgrade, and more of a complete side-by-side install.  I noticed that the 2-version is still installed, which is also kinda annoying.

I have not changed my preferences and I checked it.  I have it set to put exif data in the output.  I normally output tiff files.  But I also output jpegs neither one ended up with Exif data from the original file...   I'll post another problem I'm having separately after upgrading to 3.02.

So I had to retrieve the Exif data with exiftool from the original file after editing with gimp.

I have two different images open in two different windows, so my single window mode is unchecked.
However, I can't create  two separate layer panels, one for each window. I have no problem showing a panel for each window, just clicking on the images
alternately, but I can't show them together.
The tab is detached, as shown in the screenshot. Also, I can't load more than one screenshot.
Thank you

Hi,
I am running an old PC, window 8.1 with Gimp 2.10.8, which is the only version that behaves. (Other later versions fail on an invalidate on a DLL).

I am trying to follow a tutorial, but the bloom filter under light and shadow does not exist. From what I can tell, it should exist in this release. I have tried uninstalling & re-installing, with no luck.

Has anyone encountered this, if so, how was it resolved.
Many thanks.

Hello all,

Please excuse a rank amateur at photo editing. I'm sure I am making a sad noob mistake.
I've been editing tiff photomicrographs with GIMP- I started with 2.x and I'm now using 3.0.
I've mainly been adding labels- letters and arrows. It's all worked great until today.

The changes I made to the images are appearing in GIMP, but not in Windows Photo Viewer, or Paint, or anything except GIMP.
I've tried reloading and saving them with different file names but no joy. I have been keeping the tiff format.

Since I don't know an awful lot about editing, I haven't been changing any of the default settings when I open or save the images.
Any suggestions on how to resolve this are greatly appreciated!

Thanks

Chris

In using the brush and clone tool sometimes I encounter the problem of the colour or area I am cloning not being 100% opaque. I make sure there are no selections that could be the problem, also make sure that in the tool options it is set to 100% opacity & reset the tool options. I have not encountered this in vs 3 yet. Only in 2.10 but all was going smoothly originally so I'm unsure what the problem was.

Hello all good people,

my question is simple. Has anyone experienced that after using the ICC monitor profile, Gimp slows down significantly? I wonder if this is due to my ICC profile or if using them is generally so demanding on performance that Gimp slows down. 

Thank you 

Hi,

I have upgraded to Fedora 42, and GIMP 3 breaks all my plugins and script-fu, so 2.10.38 will be my last GIMP version.

I have been looking all day for an AppImage for 2.10.38, but all the ones I found did not work with Fedora 42.

I've found a 2.10.25 from 2021 that works: 2.10.25-20210610-withplugins-x86_64.AppImage

But this is way too old, I am sure it will break soon.

Does anyone can recommend a self-contained AppImage version 2.10.38 (or close) for Fedora?

Thanks!
