GIMP Version: 2.10 Operating System: Windows GIMP Experience: Intermediate Level List any relevant plug-ins or scripts: GEGL graph I do not really want to disrupt the Learn GEGL thread so: mackenzieh wrote Quote: I'm curious as to what this plugin does. see: viewtopic.php?f=10&t=19463#p265540 The GEGL graph in Filters -> Generic lets the user run GEGL operations interactively. Those with a 'G' in the menus. What is the advantage? Why not use the filters in the menus ? The GEGL operations can be chained together and parameters adjusted without 'undoing' previous work. A trivial example, posterize an image, followed by the very nice GEGL waterpixels then the illusion filter. If I use a chain of operations like this. Code: Select all posterize I can adjust any of the values for any parameter (within the scope of the filter) in the GEGL graph and see the result. No need to undo anything to go back. very quick example as an animation. https://i.imgur.com/XtP5rfk.mp4 |

Interesting. I guess this will replace script making for many instances. Just make your own filter combinations and save the presets. |

Not impossible to script GEGL operations with Gimp 2.10 there are examples somewhere (but not easy). So you could make a collection of "boilerplate" text files for specific tasks. or as you say, save as a preset. (a blank without all that commented text is a good start ![]() The place for GEGL filters and syntax is https://gegl.org/operations/ |

It is interesting to see it in action. I'm glad you posted an example because I had no clue what the plugin did. |

It crashed for me too even when just typing an =. Something is wrong with it. My expertise is making layer effects in GEGL. I am trying to make a new GEGL filter that allows multiple strokes, a shadow, a bevel, and image file overlay. I will name it GEGL Effects and it will be able to make all sorts of stylish text in a GUI. I can't figure out how currently. I need to better familiarize myself with GEGL's source code. |
