is there another version of jit.alphablend that preserves transparency?

    Sep 29 2013 | 6:55 pm
    The way jit.alphablend seems to work is that any cells that were fully transparent on input are converted to fully opaque black on output, i.e 255 0 0 0.
    I would prefer if the full transparency of the cell was preserved, e.g. 0 0 0 0.
    This would mean I could take the output and use it again for alphablending further down the line.
    I'm having a go at writing my own abstraction to do this, but any advice, or links to an object that may do this already, would be appreciated.

      This is beginning to drive me a little crazy - any help much appreciated!

      just repack in the alpha plane with the jit.alphablend output (or better yet, use jit.pix and customize however you like):
