| Post subject: | GEGL Fog Effect |
I ported the existing python fu operation to GEGL. I could have made it where the fog covers the entire composition regardless of size but that would have ruined the ability to add fog to images with excessive height. As a result you have to manually input the pixel size on very large images. If you click the height and width box and input numbers you can manually change the pixel size.

I downloaded the effect and have yet to experiment with it. I'll let you know my thoughts. |

Tested with an existing image. It certainly has potential.

..."If the image is very large or long you need to manually adjust the width and height of the pixels." ... Could Gegl not get the image size? Also a bit of an inconvenience with images smaller than 2048x1536:

Unfortunately, I had to make a tough decision to make it work on large vertical images and users have to manually input pixel size if the image is over 2048x1536. If I did not do this then the effect would not work on large vertical images. |

Next question: Plasma (component of the fog) also works for selection. Can You get the Select All option in Gegl (Equivalent to Ctr + A)? Then You don't need to adjust the height and width when you set their maximum in code c (= 4096). |

Plasmas fog effect looks horrible if the image is excessively vertical. GEGL cannot select anything. Gimp does not have a way to select for GEGL outside of Matting Levin and Matting Global. (which I don't have a clue on what is going on) Fog is created by the following filters. Plasma Desaturate Color to Alpha Color Ovelay Gaussian Blur |

Just hit layer to image size after applying fog. I don't seem to have that problem though |

It looks cool, I think you can make some pretty atmospheric pictures with this effect. |

Windows 10 64 bit image size - 2000 x 1770 Attachment: GEGE_FOG_TEST_WINDOWS_2022-07-15_210516.jpg [ 276.54 KiB | Viewed 721 times ] Maybe i am not using it correctly? It did indeed allow me to resize by clicking the height value but my results were just a fog image and no transparency. |

Am i supposed to create a new layer and set the mode to lighten only? |

This filter now works on single layers regardless if you use the normal blend mode or not. I did not intentionally do this originally but I choose not to fix it as a way to encourage people to use layers. Now you don't need to use layers or the normal blend mode. I can do the same to GEGL action lines |

I can do the same to GEGL action lines Thx contrast. I am waiting for Gimp to load so i can test the Windows 64 bit dll file. Then i'll add the zip attachment to THIS post. Pocholo if i do you should remove your compiled Windows version so as not to confuse others who skip thru the thread. Works Great!  Attachment: GEGL-Fog-Works-GREAT_RD-2022-08-23_022317.jpg [ 311.71 KiB | Viewed 644 times ] DLL file attached. Attachment: Just unzip to AppData/local/gegl-4.0/plugins folder. THIS WILL REPLACE THE OLD Gegl_fog FOLDER! So when it asks you to replace allow it to. |
