Hello, im trying to get image 1 to look like image 2. i need the inside of the design to be transparent. been trying to figure it out myself for days. any ideas. thanks


       

Has anyone got a reasonable solution for creating graphics for print in Gimp (in my case book covers and photos inside the book) and they look great in RGb but when converted to CMYK for the printers they come out too dark and/or dull?

I really can see use of the in the case of planetary objects such as the Moon/Sun. "Astrophotography" shots.  Where the pattern of the light is brighter on the outer-edge of the disc (maybe) and you might want to apply a black-level from the outer edge inward at greater levels..... Or visa-versa (depending on the shot.)  It would be nice to have control like that. 

Some anti-vignetting tools give some control to apply similar controls to what I'm talking about.  But a custom Black-Level tool if someone knew how to create one would be cool.  Or 'Contrast-Apply' tool.

sometimes if I'm doing a half-moon, it may not be a perfect circle.  so it should work with the box-select and/or free-select tool.
or if you can think of another solution.  

Obviously I get by with 'Levels', 'Curves' and Balancing the 'Shadows-Highlights' screens.

Can't access this site, both FF and Chrome say there are too many redirects.

Is it working for you?

After investigating what's going on (wrong) with Ubuntu 24.04 I've come to the conclusion it's permanent.

   

Canonical and Msoft has been working together for some years now with Msoft attending Ubuntu conferences. Nothing wrong with that except these are contradictory economic systems. Ubuntu get most of their software for free from Debian and volunteer programmers. Somehow this good will has been corporatized in a partnership that is supposed to be good for the users. I don't believe it. This is all about money.

It was just a matter of time before Ubuntu started breaking -down.

   

The problem with Msoft is they force people to jump thru endless hoops and deviations to get anything done. I don't like that.

So I'm moving on possibly to Debian. Debian 12.5 looks good and is a reputable distribution. BTW I don't thing Mint is going to be sucked-in to the Canonical vortex

I am trying to install a a plug-in on 2.10.36. I go to edit - preferences -  folder and expand and go to Plug-ins - I choose the top line and open it -  Can't show file in file manager: ILCreateFromPath() failed 7. How to I correct this??

I am new to Gimp,and a friend has asked me if I can change pictures of him.The pictures are of him "front on".How can I flatten his stomach using Gimp ?
Can someone tell me what tool/tools to use and where I can find a detailed tutorial please,I prefer written tutorials so that I can print them out,rather than utube tutorials.
I look forward to your replies,thank you

Windows 7 64 bit
16 GB memory
Gimp 2.10.36
560 MB TIF file

When working with Selecting in a 560 MB TIF file, Gimp became unresponsive.
After bouncing around with Fuzzy and Invert, I think I was using By Color when Gimp got fed up.
It did recognize a mouse click on the "x" to exit, though.

When Selecting in the 500 MB image, memory usage went to about 7.5 GB, not all Gimp.
But I didn't catch Task Manager's display when Gimp fizzled.

Is there some way I can gather info to identify the cause?

Hello yet again,

I have learned a LOT by experimenting and watching tutorials but my next problem maybe impossible to solve with an automated tool. I am trying to remove the background of the following 2 images leaving only the dials and the numbers on the outer ring and also remove the center hole.

I tried an auto background tool, change color by selection, changing chroma, but too much gets removed. Unless the experts here can help my last option is to use the free selection tool to remove the background by hand.

Thanks!
