I am very new to Gimp, and my goal with this image is to change the brick red to fuschia. So far, I have Indexed the Image Mode to 32 colors max, and I am having trouble with using Color Exchange. I chose the "From color" from the image itself, and I want the "To color" to be fuschia. I have tried messing with the red/green/blue thresholds, but I think I am missing something. 

Thanks in advance!

Does anyone know where I can find the privacy policy is of gimp?
What information do they collect on us and whatever we publish?

Hi, I have suddenly developed an issue with my scaling tool. When I am working in a layer, instead of scaling just that layer it scales everything at the same time, including the transparent background underneath. Is it possible that I may have altered something on the tool without realising? Be grateful for any suggestions. Thanks.

Hello! Is there an easy process to create a text shadow like in the image?

I know how to do it with complex operations, but is there a simple solution?

I'm currently working on a project with road stripes, and the centerline is being exported from a program. The issue is that the line type exported is the "smooth" type (right line), and I need the pixelated type to make it work. Is there any easy way to convert the line over near perfectly? Any help is appreciated.

Gimp:  Using latest update.
Tablet:  Huion Graphic Tablet Model 420

When drawing a normal stroke with pen, it leaves dots about 60% of the time, not lines.  Makes it very impossible to draw.  My tablet works in other programs like Paint and Photoshop.  Any suggestions?

• I have uninstalled and reinstalled Gimp.
  
• Reset Huion tablet settings, checked pen sensitivity.
  

Could anyone help me with a list of instructions of how to overlay two images to make one., I know this is an easy task but I am totally new to image manipulation software and am struggling to achieve a good result? Many thanks to anyone that can spare the time to help out.

Cheers

Hi is there a video on how to merge three images? If so can anyone point me in the right direction?

In game engines and 3d software, to counter transparency issues, they use a technique where they fill the transparent parts with the borders or edges of non-transparent parts, I don't know what this technique is called.
Here's an example with fortnite, but all new 2d and 3d games do this.
   
   
-What is this technique called in for example photoshop?
-How can you do this with gimp, preferably automated with a script?
Thanks in advance!

I'm fairly new to Gimp, so this might be a straightforward answer.

I have a collection of images that are a solid color with transparent backgrounds.

This is a crude example. The left arrow is the type of image I have where Green is the solid color and White is transparent.

My goal is to add borders like the red in the example. 
The middle adds a single layer of pixels outside of the original, overwriting some transparency.
The right replaces the outermost layer of pixels with a new color without replacing any transparent pixels.

Clearly the optimal solution would work for any number of pixels.

The images are not simple polygons so I can't just use a specialized rectangle/circle/etc drawing tool.
I created the example by using the pencil tool and manually changing pixels to red. This is not feasible for larger images.

Also avoiding some sort of smoothing would be nice. I want the border to be a solid color. Any solutions that involve smoothing are still acceptable.

Thanks for any and all advice!
