I would like to change this line into a half circle?

Also can I control where is the center of this half circle?

   

I have tried several things in order to export this image with a transparent background, i.e. select "Export As", selected PNG as format, checked AND unchecked "Save background color", same with Gamma, et al...nothing's working

File attached, and any help is sincerely appreciated!!

I used 2.10.14 to create a palette from an image. It has 256 colours and it is sorted in a random manner. Can we sort it automatically in such a way that similar colour shades are grouped together

Do you think that it is worth using Webp for animated images through GIMP 2.10 ? I found how to do it, but I am not sure whether I will be able to upload one here, or Imgur.

I have a cartoon picture that came with an outline. I want to thin the outline either by making the inner color areas bigger or the outline thinner, it doesn't matter. Is it possible to some way negatively stroke a selection? I tried to put a minus sign in the pixel line width section but it just auto-set to 0.

I want to vary my line thickness as I paint to match a style of an image, but can't seem to find how to input this setting I'm reading about, varying the mouse size with how fast you move it. I'm sure one of you GIMP wizards must know TIA

I have seen this effect used quite a bit for cell phone themes and I wanted to have a go of it with my dog as the subject. I found the bones of the procedure here, but it gave really poor results with the pictures I wanted to use. (Black dog doesn't seem to help here.)

I ended up having to dodge and burn different areas to get better results with the rodilius filter and I also used g'mics Might Details at the end to help it pop a little. There are certainly areas I want to tweak further but it's getting close. Any pro tips out there? 

       

Hi, I am new here, first post. I have been using gimp for many years but with the new version I was really pleased that I could finally add keywords in the metadata so that my images are searchable in my work's image directory. I need this function for work so was very disappointed to find that no matter what I try it adds this coding Type="bag" when I export it as a jpg. This is causing a problem with my work's image directory and I'm desperate to fix it so that I don't have to take on a photoshop subscription just to keyword. Can anybody help?

I've been using the quick mask function (maybe that has some connection?) and tried to export the picture as normal in a png, which I've done before on this same picture, but this time it exported as a black box, just the color black filling up the whole image. I was backtracking some steps so there's both an undo and redo option available, as in it's in the middle-- could that be why it's exporting weird? It let me save it as a file while in that middle state so I don't see why that'd interfere with exporting the image.

My goal is to import a couple third party Python packages for use with my GIMP installation. This will allow me to use these packages when developing a GIMP plugin. I noticed a few directories that may be of use. They are as follows:

C:\Program Files\GIMP 2\32\lib\python2.7

This directory contains a site-packages folder which contains packages such as requests and pip.

C:\Program Files\GIMP 2\32\bin

This directory contains a python.exe. When I run python --version in an elevated cmd at this directory path, the output is Python 2.7.16, which I assume is GIMP 2.10's version of Python. This is important because I have my own installation of Python 3.8.0 in my Program Files. If I'm anywhere outside of this path in the cmd, the version that outputs is 3.8.0.

I have added these directories to my PATH system variable and tried running pip install but the output tells me I have already installed the requested third party packages. The problem is that they are installed to my Python 3.8.0 installation. I'm trying to run pip install in the context of GIMP's Python environment.

Any advice would be much appreciated.
