I'm working with JavaFx and i'm looking for an equivalent of the
AWT BufferedImage. I saw that I can used
SwingFXUtils to used an
awt BufferedImage with JavaFx but I don't want to used
In fact I'm looking for a structure to display a table of pixel witch is associated to a
Does anybody know some equivalent with JavaFx ?
Thanks a lot.
The closest you get to a
BufferedImage in JavaFX is
javafx.scene.image.WritableImage. It is a subclass of
javafx.scene.image.Image, and was introduced in JavaFX 2.2.
Depending on your use case,
javafx.scene.canvas.GraphicsContext (similar to a
Graphics2D Java2D) might be a better fit.
To paint on a
Canvas node and get the contents in a
WritableImage, use (adapted from the
// Create canvas Canvas canvas = new Canvas(250, 250); GraphicsContext gc = canvas.getGraphicsContext2D(); // Paint on it gc.setFill(Color.BLUE); gc.fillRect(75, 75, 100, 100); // NOTE: The canvas must be part of a Scene for the following to work properly, omitted for brevity // Obtain a snapshot of the canvas WritableImage image = canvas.snapshot(null, null);
See Working with Canvas from he JavaFX tutorials for more information.
