Hi folks, originally posted to another GIMP forum until I realized no longer active.

Total newbie here following tutorials for background blurring.

Only issue appears to be the exclamation mark at the 'feathering' step, the defaults appear to have changed but cannot find anywhere a reason for red triangle - results vary on two different machines with same GIMP 2.10.8 and OS, Win 2010 Pro.

Tried various images and ratios thinking it could have something to do with aspect, and or ratio with background image -

Accessing the online help doesn't give any clues either, help appreciated.

Thanks,

I have a rather simple black and white image that's going to be used as a depth map for engraving.  I need the blur between the black and white areas to create shades of grey, but I want the black areas to bleed into the white in a way where the black areas will remain completely black, and only the white areas will change to become more grey in the border areas.  Hopefully that makes sense. can anyone tell me how to do this?

Okay so I'm having problems with my tablet and GIMP.
I have GIMP 2.10
My tablet is the Wacom Intuos
and my computer is a Windows 10 w/ Core i7-7700 CPU @ 3.60GHz

whenever I click 'save', It says error and permission denied. Can someone help me?

Good morning! I am needing some help with one of my images. I have a png image of the world map. I need to fill the entire image with a different color. And on a separate one, I need to fill the entire image with a pattern. I don't know how to fill in all of the tiny little islands on the map without having to click on each one. It would take forever. Also, I know how to do it with the paths tool. but on an image such as the world map, there are thousands of dips and curves, and if I don't get it perfect, the map will be ruined. Is there any way I can just select the clipart and fill the whole thing without drawing around it with the paths or laso? I am at a loss, and I see so many maps with different designs in them all the time, I know there has to be a way to do this!!



Thanks in advance 

Hi, I am trying to reduce the number of colours from over 17k to just 7 colours to Black, White, Blue, Yellow, Red, Light Grey and Dark Grey. If refer to the attachment, you may get a clearer picture. I am being bothered by those colours exist in between two colours which does not match with any of the colours. I have tried everything available in GIMP but could not solve the problem. Is thee any other way? Thanks.

My brushes menu is out of control. I've added several new ones, most of them for special, limited use. To further complicate things, a couple of stray clipboard images appeared at the top of the brushes menu. ??? I found some tags at the bottom of the Brushes menu that seem like they should limit the display, but nothing happens when I click them on and off.

Does anyone have a good strategy for sorting things out and managing this mess short of moving seldom used ones into a detached storage folder?

Is there a plug-in to manage brushes similar to the Photoshop method of swapping collections in and out?

And how do I exorcise those clipboard images?

I am working on a project to measure the various components of light in a night scene and need to stack and average multiple images.  I am doing this using layers in GIMP 2.10.8 and hope to reduce the opacity of each stacked layer; eg 100%, 50%, 33%, etc.  However in a simple test using just two layers (Black, 0.000, at 100% opacity and above that White, 1.000 at 50% opacity) the resulting "visible layer" pixels had a value of 0.737 not the 0.500 I had expected.  I am not sure what I am doing wrong but would appreciate any advice on how to stack say 10 photographic images which gives equal weight to the pixel values in each image?

Hello, everybody.

I've been looking on Youtube for tutorials on how to do color scales to make Synthwave image manipulations using GIMP. So far, the only videos I've found have been for doing it in Photoshop, and even then, almost all of them have been in either Spanish or Portuguese (and I speak English). For example:
https://www.youtube.com/watch?v=eePbtDQmylc
It's been a compounded problem for me because there's been nothing available for Synthy/Retroey-type art. I've tried using pretty much everything in under the "Colors" tab in Gimp 2.10 (Balance, Temperature, Saturation, Shadows-Highlights, Levels, Curves, etc). I can't figure out how to make it work.

Can anybody offer any techniques?

I got Gimp 2.10.8 installed and running on my 'Windows Subsystem for Linux' on Windows 10 Pro 64-bit, starts very quickly which is a welcome change to the normal Windows waiting experience, however I can't seem to add any plug-ins, palettes, brushes etc etc to the setup.. 
I put them in 'home/zero01/.config/GIMP/2.10/plug-ins (../palettes ../brushes)' etc  but to no avail - does anybody have any information on this? maybe a command-line (bash) fix? 
I managed to get gmic up and running with 'sudo apt-get install gimp-gmic'.
Thanks.
