Batch Color Replacement Tips? (Bimp)

One problem is BIMP cannot use GEGL filters - the ones with a G icon, so the Gimp 2.10 color-exchange is not available.

Too many screenshots so check the attached PDF

You can use a color-exchange.exe plugin from Gimp 2.8 That goes in your User Profile plugins folder (1) and shows in Colors -> Map -> Color Exchange (2)

You can run it to check out a swap and here is the 'wrinkle' The plugin dialog uses 0.0 to 1.0 sliders (3) , while in BIMP the plugins needs 0 to 255 values. Use color picker option, set LCH and 0..255 and note the values for later on (4)

In BIMP for 'Other Gimp procedure' use the search function for exchange, there is only one entry. Enter the required values (5)

A quick check and that works here, as the before/after insets.

Attached color-exchange-win64.zip (remember to unzip it) and the PDF with screenshots.

This is really really close to what I need! The only wall I'm running into right now, is that when I'm trying to input the (from) numbers, it seems to round up/down the value, and doesn't allow for the precise digits (i.e, 87.4 becomes 87).
When running the batch process with those inputs, it doesn't seem to change the image.

I'm going to continue to play with this, because it might be an error on my end, but if you have any idea what could be wrong, any help would be hugely appreciated.

Thanks!

EDIT: The stupidest GIMP user award goes to... PixelGimp!

I just realised the output folder was different, it was working the whole time! Thanks so much, this is actually perfect!
