Hi
I am a complete noob to GIMP so please be gentle   
I have a PNG file that shows the outline of a weapon in black and I would like to edit this and change the outline to blue.

How do I do this in GIMP?

I've attached the original PNG image.

Thanks in advance

Hello, how to paste an image into a round vector and make it follow a line of that vector, I tried but it did not rotate when following a line vector and was distorted in some parts, how to do this in the gimp?

Please keep in mind that I am mostly ignorant when it comes to using Gimp 2.1.  I am making a cover for the book I just finished.  The main image I'm using for the front cover needs to be made slightly transparent.  Here's what I've done:  First I clicked on the image (which is, I believe, my second layer) and then used the "Opacity" menu on the right to try and adjust the image.  What I get is a checkerboard.  Totally weird, at least from this newbie's point of view.  What is happening and how do I get this to work for me.  (BTW something I read seemed to suggest that it mattered what type of file your image was saved as.  This is a JPEG.)

I have been unable to discover a way for a script to paste from the clipboard (clipboard image created by "PrtScr" key). I can obviously use the edit>paste option to do it manually (which works), but the procedure in a script using "gimp-edit-paste-as-new-image" does not return an image. I realise that the procedure notes state

"This procedure pastes a copy of the internal GIMP edit buffer to a new image. The GIMP edit buffer will be empty unless a call was previously made to either 'gimp-edit-cut' or 'gimp-edit-copy'. This procedure returns the new image or -1 if the edit buffer was empty."

and the clipboard is not mentioned (whereas it is in pasting brushes and patterns).

I have not been able to find anything on this after many hours of searching.

My question is "Is it possible in TinyScheme/ScriptFu?"

Greetings Gimp Users,

I'm a total beginner with Gimp and am completely stumped. I combined two images by layering one over the other. I zoomed in to one layer and touched up some details with the clone tool. When I zoomed back out, the whole image (both layers) is covered in black dots. An example of what I mean by "black dots" is attached. Why did this happen? I can't figure out how to undo it so I want to avoid doing it again. Any insight would be appreciated.

Thanks,
Dank

Hey I made some scripts and tools for making frame animations on Gimp I hope they are useful, please let me know if there are any issues or things you might also want.

List :
Layer group duplication
Onion skin effect
Set visible or Opacity of all layers
Create a layer group with X amount of frames (lower than 60)

Here's a video tutorial on using them : https://youtu.be/g1zaQ89nTQU

I'm trying to design my own smart watch faces, for my watch, which I've done before, by copying images, and editing them. I've found a png watch face I want to use, but on the background I'm using, it doesn't stand out very well, so I want to add a glowing effect to the image. Can this be done? I've seen tutorials, on creating text, and giving it a glow, but this image is already created.

   
I've been experimenting with coloring a line drawing. A made a quick sample shingle roof, imported it as a TIF into Gimp. The lines were pretty gray so I needed them darker. Erode didn't give me the results I wanted so, I used Select By Color and darkened the lines. I wanted to color in the tiles individually so I took a small sample, colored it all  a darker gray color with the intention of returning to make a few of the shingles a lighter value. But adding the color had the effect of "erasing" the lines defining the individual shingles so when I tried to color a single tile the lighter color the whole thing turned the lighter color.

How can I set this up to keep the line art and color individual shingles?

Hi,
I use kubuntu 20.04 and Gimp 2.10.18 packed from distro.
GIMP interface is in English, and I don't see the choice to change it another than en_US. I have system language in Catalan.
Could you help me, please?
Thank you

I copied one image to be pasted into another image. In the existing image I selected the area where the copied image should go, hit "paste into Selection" and get a blank field the size of the copied image surrounded by marching ants. But no copied imaged image. I cleared any possible remnant selections with "select none" on both images and tried again. Same result.

Any ideas?
