During these days I played with one of the Brian's filters I like:
- Flamboyance
I did some simple modifications to the last version of the filter by Brian (5):
1- removed the references to old G'mic versions
2- set the layer modes to the current syntax
3- added the possibility to choose the size of the outcome (as suggested by Issabella)
About point 2: if you encounter problems pls tell me, because in my Gimp samj's environment the old syntax is accepted so I can't detect residuals.
About point 3: if you like to have outcomes of a size different from the source size, you may choose a new one, but for the methodology I wanted to apply Brian's style, i.s. indicating the required width in multiple of 250, as for the working size of the filter.
Playing with the working size of the filter (original Brian's idea) gives many different outcomes, try it.

Here my adapted version:


Enjoy

Just an example of changing the working size:

- default size = source (0)

- setting width = 1000 (4*250)

- setting width = 250 (1*250)
