I tried asking chatGPT for gegl filter for GIMP and it started giving me this xml
<?xml version="1.0" ?>
<gegl-operation>
<name>gegl:inner-glow</name>
<title>Inner Glow</title>
<categories>light</categories>
<description>Adds an inner glow effect to an image or shape.</description>
<params>
<!-- Color for the glow -->
<param name="glow-color" type="color" default="1.0, 1.0, 0.0, 1.0">
<description>Glow Color</description>
</param>
<!-- Glow intensity (blur radius) -->
<param name="radius" type="double" default="10.0">
<description>Glow Radius</description>
</param>
<!-- Blend mode for applying the glow -->
<param name="blend-mode" type="string" default="normal">
<description>Blend Mode</description>
</param>
<!-- Glow opacity -->
<param name="opacity" type="double" default="0.8">
<description>Glow Opacity</description>
</param>
</params>
<input-pad name="input" />
<output-pad name="output" />
<operation-chain>
<!-- Create the inner glow by blurring and blending -->
<!-- 1. Create an alpha mask from the input image -->
<gegl:extract-alpha />
<!-- 2. Blur the alpha mask for the inner glow effect -->
<gegl:gaussian-blur radius="${radius}" />
<!-- 3. Add color to the blurred alpha mask -->
<gegl:color-to-alpha color="${glow-color}" />
<!-- 4. Blend the glow effect back onto the original image -->
<gegl:over opacity="${opacity}" mode="${blend-mode}" />
</operation-chain>
</gegl-operation>
does this mean anything to you. I just know it's xml and it gave these instructions:
Explanation of the filter:
glow-color: The color of the glow inside the object.
radius: The intensity of the glow, achieved by blurring the alpha mask.
blend-mode: The mode used to blend the inner glow onto the original image.
opacity: The opacity of the glow effect.
Steps to install and use the filter in GIMP:
Save the above XML code as gegl-inner-glow.xml in the ~/.local/share/gegl-0.4/operations/ directory (on Linux). For Windows, place it in C:\Users\[YourUsername]\AppData\Local\gegl-0.4\operations\.
Restart GIMP.
You should now see "Inner Glow" in the GEGL operation stack or through the search functionality.
