"premultiplied alpha".
what is it, what does it do, what does it look like without, what is it for, how do you do it???
top graphic is the template and the bottom graphic is the result with premultiplied alpha "TURNED OFF". this could be compounded by size difference if the resultant graphic has a H&W limitation.

I think I.R. Brainiac's reply may not have been far off. I understood this and that at about the same level.
I wonder if there is an explanation for the graphically inept, which I have dumbed myself down to from just graphically challenged after attempting to interpret the above.

The info in the link I provided is about as dumbed down as it gets but a simplified answer is.
Premultiplied alpha blends layers together better and cleaner than plain alpha.
Don't try to make sense of it as it relates to skinstudio/ windowblinds because it doesn't make sense. You can have 2 images side by side in an image strip that are exactly identical yet one requires premultiplied aplpha to be turned on and another doesn't.

If you really must know, email Neil@stardock, he may provide you a response as it relates, my advice, move past it, really is a tiny part of WB and only affects a few images.
