This looks like you need to convert the 1 plane left input to 

chromakey in your patch to a 4 plane matrix so that you can composite 

in ARGB (otherwise you're just compositing the binary image with the 

alpha channel, which is all white). Try inserting a jit.matrix 4 char 

320 240 between cv.jit.binedge and jit.chromakey.

From the sound of what you want to do, it seems like you might want 

to look at the jit.chromakey-3sources.pat example, using your binary 

image as the alpha channel (don't even need chromakey here, if this 

is the case, you can just use the output o cv.jit.binedge as the

Inserting the jit.matrix 4 char where you suggested worked perfectly! So

easy to overlook things once you become frustrated with something not
