Re: [PyMOL] Capturing scene pixels without writing image to disk

[Thomas H. <tho...@sc...>]

Hi Antonio,

This is currently not possible for ray tracing or for capturing the displayed image.

It's possible for deferred on-screen rendering with a callback.

def mycallback(image):
    print("got image of dimension", image.shape)

cmd.raw_image_callback = mycallback
cmd.draw()


Cheers,
  Thomas
