Reverse Color Effect Plugin

What's this?

This is a plugin to reverse separately the value of each RGBA channel. This was firstly made to reverse the alpha channel to obtain some nice effect with transparent rendered textures or objects.

And I decided to extend to the other RGB channels...

Download it!

Plugin reversecolor.dll

ar.pngHere is the DLLal.png

Created with CodeLab...

The source is available with the plugins package!

How to install

Close Paint.net

Unzip and (re)place the DLL in your Effect folder usually: C:/Program Files/Paint.NET/Effects

The User interface

This plugin is added to the menu Effects, submenu Color.

Inverse Red/Green/Blue/Alpha:

...check the box to reverse the desired channel.

Minimum Red/Green/Blue/Alpha:

...choose the minimum value. If the channel value is lower then the channel doesn't change else the value is reversed.

Maximum Red/Green/Blue/Alpha:

...choose the maximum value. If the channel value is higher then the channel doesn't change else the value is reversed.

So to be reversed a value must be in the range Minimum, Maximum.

The Examples:

This is some guide lines on how to use this (and what for):

Example A:

A.1. On a new image with white background, add a new layer.

A.2. Run the kaleidogen

I downloaded it and I can't wait to start playing with it.

Your Example B.4.b gave me the idea that it could be useful in certain situations that may otherwise require the use of Conditional Hue/Saturation that I could never master.
