JavaFX plugin does not show canvas.graphicsContext2D.pixelReader

I use the JavaFX plugin in IntelliJ IDEA with Kotlin. It shows the canvas.graphicsContext2D.pixelWriter object but not the pixelReader object. Why is that? Is there a problem with the version of JavaFX I am using? How can I find out which version of JavaFX I am using?

I do not think that it is a question for general kotlin forum it is not about kotlin, but about Java plugin for IDE. Also the information you provided is not enough to understand the problem.

Agree. Also I have come to realize in meantime, that Pixelreader is in fact an interface not a class.
