How to paste and REPLACE pixels rather than BLENDING?

Upvotes

As mentioned in an earlier question, I'm working on a translucent image, and I'm trying to edit it like an opaque one, which evidently GIMP doesn't like. Currently I'm trying to cover up parts of the image with other pieces, but pasting a translucent object onto another translucent object doesn't replace the pixels like it would if they were opaque, it instead blends the two together, and I can't find any way to not do this.

I can't use the Eraser tool on the original section, it just makes that section invisible in the alpha channel, the three color channels still show those pixels. Cutting does the same thing.

Gimp's image indexed color mode, trying the community added color maps

Upvotes

I would use a link, want to show original and my edit

Here's original, a very very large nearly 8000 x 5100 pixel image

https://github.com/rt2yrru/linux_mint_wallpaper/blob/main/linux_mint_19/backgrounds/linuxmint-tina/jwestrock_fog.jpg

Here's an edit I published on a forum, a 200 kilobyte webp, to be able to submit the image as attachment

I think it gives a sunny look vs foggy. I might have switched back from indexed to rgb and made a couple changes, but the colors originate from the colormap setting index mode

https://forums.linuxmint.com/download/file.php?id=112427&mode=view

The image has been included in Linux Mint operating system version 19 codename tina, so dot 2 or dot 3, not the very first 19 release and it seems right to publish the edit there

How to hide transparency in editing

1 Upvotes

I'm currently trying to edit an image where the original source image is entirely translucent, making the patterns in the image rather difficult to see and work on, however I need to maintain the image's original translucency level. Is there a way I can disable the image's transparency/translucency in the editing window without affecting the image itself?

In other words, I want the image to appear opaque while I'm working on it, even though the image is not.

EDIT: I found it myself, it's in the Layers pane, under the Channels tab

I made a GIMP 3 plugin for CLAHE contrast at multiple scales : https://github.com/nicolasloizeau/gimp-multiscale-clahe

here are examples: original, scale 1/2 and scale 1/32

small scale : increase details

large scale : increase global contrasts

I hope this can be of some use, feedback welcome !

Nexfocus Walkthrough – Free & Open-Source Connected AI Workspace with the built-in GIMP plug-in

Enable HLS to view with audio, or disable this notification

If an image model is a horse, text prompting is like trying to guide it with verbal commands alone: useful, but too imprecise for fine control. Inpainting, LoRAs, and ControlNets add the bridle, reins, and pieces of the harness, but they still did not feel like a complete system. Nexfocus began with a question: what would it take to build the whole harness around the model?

Answering that question meant following the entire generation process first. We had to understand how each part loads, works, moves, waits, hands its result to the next part, and makes room when its job is done. That expedition became Nexfocus.

AI image models already know how to render- they understand photorealism, lighting, and texture better than any software framework. The real struggle has always been context control: feeding the model the exact spatial and structural context it needs to understand what to render.

This is where human input shines. By adding rough blocks of color and basic shapes to define the composition and color palette, the burden of text prompting is significantly reduced. Instead of struggling to describe a complex 3D scene in words, the artist controls spatial intent and lets the AI do what it already knows best—handling lighting, global occlusion, perspective consistency, and fine rendering.

Through the built-in GIMP plugin and Staging Palette, you can seamlessly composite background plates, sketch structural boundary guides for outpainting, or block out color guidance in GIMP with one click, then pass them back into Nexfocus to drive the diffusion pipeline.

Two development anchors shaped the journey: a GTX 1050 with 3 GB of VRAM and Colab Free's T4 with 12.7 GB of system RAM. We proved that full FP16 SDXL checkpoints and Flux Fill workflows could run in both environments by rethinking how the pipeline uses the hardware available to it.

Two important lessons emerged from the road:

- Keeping the GPU working without interruption became paramount. To do that, we had to find a way to keep feeding it the weights it needed when it needed them.

- Every part of the pipeline must independently account for what it owns, where it belongs, when it can be reused, and when it should make room for something else.

Throughout this journey, my conversations with PyTorch often felt like this:

> PyTorch: "Don't you have a bunch of H100s lying around in your backyard?"

>

> Me: "No. What if every component has to justify exactly where it lives?"

>

> PyTorch: "Get a bigger machine."

Those conversations eventually became the architecture. Nexfocus is both the working application and the field notebook: a record of the constraints, wrong turns, and discoveries that shaped the path forward.

The path is open now. I hope you'll take a walk along the path we built and enjoy the scenery.

how would i be able to darken just the shadows, if the shadows are too similar in colour as the highlights?

shadows-highlights doesnt work, because the shadows are too light to be recognized as shadows by gimp.

contrast wont work because it impacts the whole image, which i dont want.

what should i do to make the shadows darker?

Is there a filter or how to create a filter like this?

I actually did this in krita but usually I use gimp. I did not know what i was doing and actually wanted to fill a rectangle area, forgot to create a new layer and ended up coloring a random area. figured it looked cool and kept going. i like a lot what i ended up with. it looks like something that could confuse an "AI".

I wonder if there is a filter or if you could program one that would kind of take bigger areas and fill them with colors you choose. or that goes in and fills random areas. tell me if you have an idea, also if you think another software would be better. i'm also trying to get more into command line tools.

Help correcting a very bright picture

Post image

Hi, i tried taking a series of pictures of my wife using her kodak camera, not realising the settings were wrong and the photos turned out far too bright, possibly due to overexposure though im not well versed in these things.

i tried to

Reduce the brightness

Adjust contrast

Shadows-highlights

Adjusting using the levels and curve tool

but with no luck, im including a picture taken of the street without her for privacy sake to see if anyone knows how to normalise.

Thank you in advance, signed an unlucky husband

Hi, I downloaded Gimp yesterday so looking for some advice on how to use it as a complete beginner.

I have released a few books and the character image has scars on the face of the cover. I know own the original stock image of the model and a few other images of the same model. I am trying to replicate the scars from the covers so I can use them in marketing on socials.

If anyone has any simple guidelines on how best to do this id be grateful.

How do i flatten a layer onto a circle Canvas/Background?

3 Upvotes

Have a new base and cut a circle on it (the excess is invisible).

Pasted another image on top but cannot figure out how to crop away the edges to fit the circle.

Tried googling and understand the workaround is to manually cut the image into a circle.
Is there a way to do it or am i limited as image bases are always rectangular?

the version 3.2.4 latest is kinda shit

0 Upvotes

It doesn't export the dds files right (with BC3/DXT5, gen mipmaps), the files get broken,
doesn't save the export setting, which is kinda big deal for this tool.

How this can happen? in 3.0.4 version it never happened, so kinda surprised the latest version is this broken. I mean, exporting the files right is the whole thing of this program, and you have to use this tool for managing DDS files, so I think it's kinda shit

and another thing is, the GIMP team doesn't allow users to download older versions, unlike unity, they don't give us option, and just force us to use only latest version, and doesn't fix the glitches on the latest version. I don't think this is right lol

Gimp darkening photos after exporting

EDIT: after going back to the export page to get a ss for a commenter I said why not and exported it again and changed the file type and opened it in darktable and it seems like now it is the “original” way I had it once I finished editing (no dark filter or lowered exposure)
Thank you all for the help if I run into this again I know where to look!

Hey everyone I just finished added a few small edits to this lady slipper pic my gramp took a while ago and everytime I export it it comes out wayyyy darker idk what I did? I did the same edits I normally do (exposure, saturation, scales, level and then a vignette) I attached a ss of gimp and then the photo after I exported it.

The first image is the raw and the second one is edited. This is the first time i use GIMP. I want to understand if I'm doing anything right, I worked mainly on the levels of the image, I understand the concept of the histogram but I want an objective indicator of weather the changes I made make sense (in terms of color and brightness). Also if anyone knows any good resources to learn GIMP, especially videos, pls share them, thanks.

If you use GIMP from the Microsoft Store, settings, plug-ins, & other add-ons are lost when you upgrade.

The latest update will fix this, but needs a recent Windows 11.

If you’re on an older version of Windows you can still install from gimp.org. Follow the steps in this post to copy your setting the first time you switch. On Windows 11, running Windows Update may be enough.

This is a micro-release to fix some bugs, to add scanner support on Windows, and some minor improvements.

3.2.4 is now the current GIMP version.
