if you connect the gemhead in [pd line] it displays a horizontal line to indicate where the image is read.
but since the green is rendered after it blocks the reading - see the tables after enabling the line.
is there a solution or workaround for this? meaning still showing a line, but having a reading in the green channel.
i've tried making the gemhead negative or the line blue but that doesnt' help.
