Image sampler to output as points not polygons

The image sampler doesn't out put any geometry. The data that comes out is a value of the interrogated image at a supplied reference location. You can have it as either colour, brightness, hue, saturation or one of the channels. How you use this data is up to you. You could have a Smaller Than component which returns a list of True/False values based on a target brightness. This pattern could then be used to Cull a set of points that represent the reference location of the image so you only get the values which are darkest etc.

Thanks Danny! How is brightness quantified? A screenshot is attached here, perhaps the "larger than" component isn't set up correctly?

L is the list of items you wish to cull on P is the boolean pattern. swap these around and it should work
