batch processing with the fuzzy select tool |

I'm new to scripting, but I have a programming background, so I think I can do this. I have Python skills.
I have a short movie, which I've exported to 570 individual png files. What I want to do is apply the fuzzy select tool, with a selectivity of 70, smack dab in the center of each png, cut the resulting selection, and save the file somewhere that doesn't overwrite the original.
I thought I might be able to do this using bimp, I've got it running, but it doesn't seem to support the gimp_image_select_contiguous_color function that I would need to do this. Maybe, or maybe I'm looking at it wrong.
When I start googling gimp scripting I find posts going back to the last century. I don't know what the best current methodology is, nor how to get started? I don't want to waste time reading obsolete documentation or approaches to the problem. So I thought i'd ask here.
I'm running on MacOS Big Sur running GIMP 2.10

Liquify - Face |

I saw a very interesting video using PS where there is a built-in effect called Liquify which allows Face deformation in a very interesting way. The video is from Pixavu ( something like that ) and was talking about making caricatures out of photos. This particular plugin can bulge or make the eyes looks big, adjust our mouth, nose etc in a way to help in process.
The video says that this feature is CC 2015 and later. Not sure whether GIMP 2.10 has anything like that. Not complaining, only checking. Thanks.

Some webp alternatives |

The Gimp webp plugin is very adequate. You can export your image and make animations easily although sometimes a bit slow. This is about some command line (CL) programs that might come in useful as alternatives.
The webp format does come from Google, their official offerings are here: https://developers.google.com/speed/webp/download
The download provides utilities cwebp: encoding tool / dwebp: decoding tool / gif2webp: gif conversion tool / vwebp: webp viewer / webpmux: create and extract anmations I have to confess that the only one I use regularly is the viewer, vwebp
ImageMagick v.7 (IM) supports webp. There is a page with all the details here: https://imagemagick.org/script/webp.php Converting an image to webp is as simple as;
Code:
magick filename.ext -quality 50 filename.webp
What is the advantage over Gimp ? Easy to batch convert with IM
Where it might come in useful is with simple animations, You can string several images together to make an animation with variable timings.
Code:
magick -delay 100 fileA.ext -delay 200 fileB.ext -delay -delay 50 fileC.ext -quality 50 animated.webp
You need to experiment but a low quality settting can provide a smaller filesize than the comparible animated gif, with equal quality and no 256 colour limitations.
A very simple example:

I am getting error messages from script-fu.
For example, I opened File-->Create-->Fx-Foundry-->Logos-->Fiery Steel. When I select the Font box to change the Font I get the following message.
Quote:GIMP Message
Plug-in "script-fu"
(usr/lib/gimp/2.0/plug-ins/script-fu/script-fu)
attempted to install procedure "temp-procedure-
number-1" with invalid parameter name "dialog status".
OK
The font can not be changed.
Any suggestions on how to correct this problem?
I am using GIMP 2.10.8 on Ubuntu Studio 20.04. Any other info needed?

how to know image opened as svg |

I opened an svg image that I exported with librecad's "export as makercam svg" option and gimp opened the svg with transparent backgroun but an ellipse in my drawing was distorted.
Then I tried librecad's "export as image" option and selected file type as svg. Then I opened that image in gimp. Now the ellipse looks fine but now it opened with a white background as if opening an image, not a transparent background. How can I tell if the second image opened as svg?
Or how can i make the ellipse look regular in the first image?
