Black and White Only Effects Plugin

Recommended Posts

Black and White Only

This is an effect plugin that is found under the 'Adjustments' menu. It allows the user to choose a level of grey, and any pixel which is darker becomes absolute black, or otherwise pure white. So whereas the built-in "Black and White" option makes the image "Greyscale", instead this plugin renders the image only either black or white, no grey at all.


It's a bit like making the image greyscale before posterizing to just a two colour palette of RGB(0,0,0) and RGB(255,255,255). In other words, each pixel's RGB values are mean averaged to grey before deciding whether to replace with #000000 or #FFFFFF, based on the user's choice.


Here's the download:

@Intrepidis Hello.  Your download link is not working. It's throwing a 404 error. Could you investigate this, please? Thank you.

@Intrepidis Thank for fixing. I noticed your 'Read-Me' file says to put the .dll in the 'FileTypes' folder.


It should go in the 'Effects' folder and is found under the 'Adjustments' menu.

@Intrepidis please have a read through the recently published guidelines. There are a couple of suggestions in there which will help users find out about your plugin (P6 & P10)

@Intrepidis, @lynxster4, @Ego Eram Reputo Just an FYI but when I download it, the file gets flagged as a potentially harmful file. Anyone else get that?

I did not. I have my heuristics set to High.

I am away from this forum for undetermined amount of time: If you really need anything related to my PDN plugin or my G'MIC filter within G'MIC plugin, then you can contact me via Paint.NET discord, and mention me.

Hello @johnff and welcome to the forum :) 


It took me 6 attempts to get that link to download.  I have no idea why :( 


Anyway, I have copied the folder to my Dropbox and perhaps you can download it from there alright:  https://www.dropbox.com/sh/gal75h8m4nvv5nf/AACD_lq04L-fizwRPCurva9Ea?dl=0
