Hello,

I would like to know if there is a way to automate some repetitive tasks in GIMP 2.10.x ?

e.g. I have several photos and I always to the same few tasks in the same order in purpose to remove the background and I would like to know if there is a way to script all those tasks or a recorder for this thing ?

i.e.
- turn image to greyscale
- change levels
- copy a mask from obtained photo in BW
- create mask layer from previous step
- get person/object only while background is transparent
- save/export result in png file.

something like that :-)

thx

Hello, I was wondering if anyone knew how to, kind of like, raise an image closer to the screen, or give it more levels? I'm working on a patch in a video game and noticing the differences between a patch I found online and editing it versus a digital one, the real patch has a certain weight to it that makes it feel more real. I was wondering if there was a way I could do that to my digital one as well? Here's an imgur link for example of what I mean

Thanks to anyone that helps!

I noticed that Gimp does not have python-fu available (only script-fu), and from what I can tell this is because Ubuntu Studio 20.10 doesn't come with python 2.7 preinstalled.  So I installed python 2.7 and the necessary 'numpy' and 'typing' packages with pip, but am still getting an error when I try to install 'pip3 install pgimp' or even 'pip install pgimp'

Here is the terminal error message involved:

pip3 install pgimp

Even though I already have numpy and typing installed, it still gives the same error message.  Do I need to configure python2.7 after the initial install before it gets recognized properly?  Gimp on my other machine (Ubuntu plain 20.04) has python-fu working already, yet it only has python3 installed and not python2.  So I'm a bit confused as to what the actual conflict is, or what the requirements are for python-fu.

Hello,

I didn't see this subforum. So, I believed that to present oneself was not intended and I started to post.
I firstly went to gimpchat.com. There, I presented my "photo to cartoon" plugin.

Hi,

Sorry but i could not find an answer in the chat or in google. I am new and i am looking for a tutorial / Script or any advice of how to make a grayscale image like the one attached. My question is not how to convert an image or photo to grayscale (this is what appears when searching in google) but how to make this specific type of grayscale image a technique that is also some time used in real photos. Any advise / suggestion will be appreciated.

Hello dear Gimp Pros,

bit of an unusual topic

I'm doing chemistry/material research. In part of my research, X-Ray data is created in the form of gray scale images. I wonder if I could use image processing in Gimp (or maybe other software) to enhance my data quality.

The data in the images consists of 3 parts:
1) Reflection points: seen as dark spots in the images. The position, size and shape (round, oval) is part of the data acquisition.
2) Fluorescence: seen as a centered dark shadow.
3) random Noise: single points all overall the image. This noise has a preferential direction (up & down), which is due to the detector type used.


The images can be created in different "Cutoff" levels, which refer to an internal algorithms of the device to remove data from the image, based on the intensity of the recorded signal for each pixel. There are 10 levels.

In one image I marked very weak signal points, that are barely visible. The position of these points can be calculated from the other data points, so there is a point to be expected.

The position and shape of the reflection points is used for further research, so this is the data I would like to extract more precisely.

Is there a possibility to reduce the amount of the noise and fluorescence from the different cutoff levels? The process would have to be a fixed routine without manual work, so it can satisfy scientific standards.

Best regards,
DuroHeci

I've been using gimp for several years now, various versions, and usually just ignore the out-of-gamut warnings as I never print anything, and likely never will.

Suddenly today a huge chunk of colours seems to have disappeared from my palette (see image) at some point while I was working, and of course they include hues that I want to use.

I have tried changing to every colour mode, turning off all colour management options, uninstalling gimp and reinstalling the new version ( I was previously on 2.6), deleting my profile, and then reinstalling again, but this problem persists.

Am I missing something obvious (probably...), or has something gone drastically wrong here?

I would appreciate any help / suggestions anyone can give, as I rely on GIMP for my work! Thanks.

Hi,

About the function Layer ➤ Crop To Content it would be expected that only the empty areas (with transparency) would be removed from the layer and if there were no empty areas nothing would be changed.

Why then, in some cases, does the cut remove areas with content?

In the example below, only the crop to content filter was applied to images 01 and 02.
• Image 01
   
As seen in images 02 and 03, part of the content of these layers was removed leaving a transparent area.
• Image 02
   
• Image 03
   
Any configuration that I am losing and that is generating this unwanted result? A bug? What would be the explanation?

New to GIMP.  Created new image (File->New) which brings up a window where I specify the width and height (in pixels).  I set these values (1092 X 1092) but then my project is too large for this size.  So I would like to "delete" the first image (and it's contents) and start over.  How is this done?  Can't figure out how to "select" the entire image and delete it.  Under Edit->Clear nothing happens.
At present the only choice seems to be to close the file and delete all changes, then create a new image and, when it is the desired size, save it to the previous name and overwrite.
Any and all suggestions greatly appreciated.

Hey folks,

new to gimp, have only used preview and photoshop.

I have a base layer with a building layout. I guess I am adding a second layer and in that layer I want to paste in 15 disks, each with its own text so there will be 30 elements. I want to grab and maybe slightly resize, and move each one to my satisfaction. The only way I am finding to do this is that I have 31 layers, one for each element.

I've tried searching but I think I am wording wrong- can't find the answer for my situation. Is it possible to paste a number of elements into a layer and move each one about?

thanks
