Paint.NET Glow Blend Question

At Layer Properties, there are several different blend modes. I have a particular fondness for the "Glow" blend function. I have been trying to program something that does the same effect, however I have not been able to find much information on how the blending equation works.

 

Before I try digging through the old Paint.NET source code, I'd like to know if anyone here eithers knows how it was implemented or resources that explain how effects like it in other paint programs work. Sorry if this is not a question I should be asking or something... I'm not really sure.

 

Thanks in advance,

Me

From my ebook...

 

The Glow blend mode squares the upper layer value and divides it by the inverted lower layer value.

So the resultant RGB value is found from

The other blend modes are also detailed in the ebook.
