Pre-Alpha Mask Plugin

[TrevorOutlaw]

Hello, experienced coders:

 

I am in need of your valuable assistance in developing a one-click plug-in.  My purpose in writing this plug in for a simple reason so I'll describe what I do in my steps prior to photomanipulations:

 

1. Convert image to fully white (this is usually done by using Curve).
2. Create a new empty layer, drag it down below the image, and backfill it with black.
3. Merge the layer.
4. Copy the merged layer.

So far what I have managed to acheive is have CodeLab run a simple script that convert all the RGB values to white.  What I want to do now is tell CodeLab to backfill transparency with solid black, and this is where I need your assistance.

 

The code is below.

Removed code since BoltBait had a plugin that did what I was seeking to achieve.

My plugin pack has what you need. 

 

Look for Effects > Object > Alpha to Gray

I honestly had no idea this was what it was for.

 

In any case, I will consider my plugin idea unnecessary.  Thanks, BoltBait.  This thread can be closed.

Just be aware that my plugin does not copy to the clipboard. So, make a copy of your layer before running.
