Do you have any Paint.NET DLL files in the plugin folder?

 

The Doctor: There was a goblin, or a trickster, or a warrior... A nameless, terrible thing, soaked in the blood of a billion galaxies. The most feared being in all the cosmos. And nothing could stop it, or hold it, or reason with it. One day it would just drop out of the sky and tear down your world.
Amy: But how did it end up in there?
The Doctor: You know fairy tales. A good wizard tricked it.
River Song: I hate good wizards in fairy tales; they always turn out to be him.

I am having trouble with Boltbait's Steganography plugin. :( Whenever I try to reveal an image, color or black and white, I get the revealed image but with scan lines as seen in the picture below.

I have tried this with pictures that I encoded myself meaning this is a problem with the reveal image part. This problem seemed to have started when I installed 3.5.1. I have downloaded the latest steganography plugin. Any help is appreciated. :D

Edit: Actually I found the problem. I feel like a complete idiot. It was that I actually didn't have the latest version. However, the version you download here isn't the same as the one in his plugin pack.

Either that or I'm making an even more complete fool of myself. :?

I have recompiled this plugin for Paint.NET 4.0.

The algorithm is the same, only the UI has changed.

Check the first post in this thread for download link. Install the normal way.

(Yes, I've been cleaning up all my older plugins. I think this is the last one. :P)

Source code to the decoders:

I just updated this plugin. Now, all hidden images are dithered before being hidden. This is the standard Floyd-Steinberg Dithering method.

Dithering dramatically improves the quality of the hidden image.

Algorithm for decoding remains the same.
