My version: GIMP 2.10.18

Hello, I am asking if anyone has a plugin or script that can do the following: taking a palette (.gpl) and converting it to an image, with one pixel of each color that the palette has.

For example, let's take the input as the Cool Colors palette included with GIMP


The end result after inputting the Cool Colors.gpl in the plugin/script would be this (very tiny 8x1 image):


I do not care if it writes the new image to the canvas, or outputs it as a file. I also do not care whether the colors are in order vertically or horizontally, and the "Number of Columns" in the .gpl can be discarded as well.

The reason I need it is because I posterized a RGB 16-million color space image to levels of 32 red, 64 green, and 4 blue (based on the amount of receptors in the human eye for each color) in Paint.NET. And now I would like to have only the unique colors from it in an image, so I can further reduce that image's amount of colors using GIMP or GrafX2 to make a limited color palette for things like pixel art/game art. For example, I already did this with the Natural Colour System's 1952-color palette. (and if you ask how I got all those colors into an image, it was using the eyedropper on 1952 color swatches!!! But my new .gpl has 8192 colors, over 4 times as much. That's the reason I'm asking for an automation)

Here is the .gpl file of my new 8192-color palette if anyone wants to use it as a lab rat if they thankfully write the plugin/script

hi in my gimp color palette a triangle appeared, months ago, in the corners of the color rectangles. i do not know how or why. it sometimes makes it impossible to do what i want to do and sometimes things seem to work normally.
can someone tell me why it appeared? what it is and how to get rid of it? ...and why colors appear there that i haven't chosen for anything?
i've clicked every icon within the color box and many things elsewhere on the page; i've tried the "help" option and i've websearched the question, phrased different ways. i've gotten no explanations and nothing that references it.

...it seems to me one effect it has is it mixes the color i've chosen with the color in the triangle (image 3)...?
another thing that i think is related is that, as my last attached image shows, i try to lighten a color, the triangles disappear (on the palette only, not on the work page) but when i try to use the new color it does not work. (ie, bucket fill - the color stays the darker one... but if i go to a much lighter shade, it seems to mix with the color in the tiangle, making a completely different color - as in image 3)

 Thank you!

Hi.


have some problems with gimp.

1. I don't have all tools on the tool bar (not sure but it's like only 1/3)
2.How to import more than 2+ images? (in 2+ sepereted windows)  For example when I wanna take a colour from 1 picture and use on other or to resize it and put later on the 2nd layer.

3.Last but not least.Soo annoying is when I want to move 1 picture the some other layer is moving.How to lock or whatever the layer.

All,

Im trying to select with the magic select tool.  When I initially click I get the outline of the selection but as soon as I let go of the mouse button the selection goes away.  I do have show selection on under view, Im on replace selection for options of tool, my threshold is 15%.  Im at a loss.  Any help is appreciated.  I even reinstalled GIMP.  Im running 2.10.14


Cant figure out how to add an attachment.....

Hello all,

Are there any ways to manage adding or removing multiple layers in a Layer Group?

Something like moving linked layers, or visible layers or whatever?

There is the Multiple Layer Actions script, but it does not perform this task.

I always have to do this one by one.

Thanks!

Hi all, I have a question about alpha channels. When I click the eye icon next to the alpha channel of a layer to hide it, then export it to PNG, the exported image still has the alpha channel. However, removing the alpha channel entirely produces a different, unwanted result, turning the image blue-ish. This blueness is kept when exported.

Is there any way I can export my image to a PNG so that it looks like it does in GIMP with a hidden alpha channel?

Thanks!

I have a significant number of jpegs that require editing.

I prefer to save my edits as png doing the following:
(1) Shift+Ctrl+E
(2) Alt+T for Select File Type (By Extension)
(3) mouse click on "By Extension"
(4) Type "png" press Enter
(5) Alt+E for Export
(6) Alt+E for Export
As you can see, I use keyboard shortcuts and do so rapidly. However, for such a large volume of jpegs, this becomes time-consuming and laborious.

Is there any way to automate this process? Grateful to hear if there is a way to do so.

Many thanks

Can anyone tell me how to remove the dark splotches in the background of this image. Some of these dark splotches are up against the hair of the monkey. Is there a way to mask the monkey using Edge Detect, and if so what are the steps?
