hello, I want to layer black&white JPGs in a live performance.

is there a better way than [jit.op @op *] ?

my MAC, 2.7. Core i7 needs some time for this layering process - it is becoming slow.

Are you using JPGs that are much bigger than the screen reolsution? If so, you can resize them in a photo editor for better performance.

Have you considered using jit.gl.slab and one or more composite shaders? This will offload the processing to your video card's GPU. See the example composite.shaders-help.maxpat in Cycling '74Max 5.0examplesjitter-examplesrender

about resolution. I am always unsure about the right resolution for projecting.

hi, thanks for your reply.
no luck with jit.gl.slab.
I will check the examples.
