I'm trying pack 3 grayscale textures in a RGB file, one texture for channel.
None of the tutorials and docs that I find works...

How can I paste grayscale data in a selected channel?

Is it possible at all in Gimp?


* Edited with a solution

Solution:

1- Uninstall Gimp 
2- Install Krita

I have hid all layers and still there is something visible.. what is that ?  why is it visible ? 
I have drawn the cloud like thing with path tool.. but somehow it is not added into layer.. why ?
Appreciate if somehow point out the problem.
Thanks

I am using GIMP 2.10 on a Macbook Pro OSX 12.3.1. When I try to export a 16 bit XCF file as a 16 bit BMP R5G6R5 file, I wind uo with an 8 bit BMP file.

What am I doing wrong?
I have a pic.
I want to put some text on it.

I import the pic.
I make a duplicate layer.
I hide the original layer.  (this is my attempt to keep my original untouched)
Then I write with the text tool and this automatically creates a 'text layer'  right?
then I try to move the text around or the text layer around or something to get the text where I want it.
But the underneath layer moves instead.  That's the duplicate layer.
I make sure the text layer is selected and it seems it is.
?

Hi,

I have created a semi-transparent glass "texture" (see attached image) in Gimp 2.10 which is just a single color. I filled the layer mask with 34 (dark grey) and applied it but Gimp outputs the alpha value as 4.

I have opened the image in Photos (the Windows app), which has a background color of #222222. If I put another layer behind the glass texture in Gimp, fill it with #222222 and merge the layers, I get (45, 48, 48). In Photos, the color is (36, 37, 37) and Adobe Photoshop gives me (37, 37, 37).

What is going on?

Hello everyone!

When a layer is selected (alpha to selection) and I use the scale tool to resize it, it leaves marks/outlines of the original size.
How can I prevent this from happening?

Thanks for your help!

Hello everyone,

I've been using Gimp 2.8 for years and since 2.10, there are some behaviors I really don't get. I searched for hours on the net without finding solutions because I think I miss keywords.
It's really simple, I have three layers, from the top to the bottom :

- Random white text 
- Layer opacity 10 which is a glow aura of the text 
- Black background

When I switch the black background to a transparent, the aura is diminished to the final export (see attachment). Why? My low opacity layer is the same whatever the situation, it's not supposed to behave according to the layer below it.

It gave me a lot of headaches for a long time. This behavior is clearly different from previous version of Gimp. I let 2.10 to the side for a long time because it literally destroys a lot of projects and I suspected a bug, but now it's 2.10.30 and it's still there. In 2.8 and before, layer is a layer, that's all, it doesn't disappear or change because of what you did on another layer. I feel like a total dumbass but can't manage to find anyone talk about it.

Thank you everyone by advance!

Sorry if this has been asked before but I couldn't find anything using Search. Can someone please explain to me why it's not possible to enter (manually or copy and paste) a path in any of the dialogs for Open, Save, Export? It is so not user-friendly and I can't for the life of me imagine why it would be designed this way. And can someone please also tell me what the "Search" is for in these dialogs?
