Using bitmap files to add or subtract in a blend?

acealmighty13

I may be missing something but can I use a JPG file, black and white information, and use it with a blend node to add or subtract the information?  I've been messing with it and the Bevel node picks up the edges and I can adjust the sliders with success.  Yet, this bitmap mask isn't playing showing up at all in a Blend node.

Could you attach a few screenshots? It's hard to figure out what you are trying to acheive without any visual.

The 2D view is of the blend node and the graphic was moved up high, hidden underneath the Transformation 2D label.  Ignore the model, I was working on another project when I came to respond to your reply.
