Examples of WritableImage

javafx.scene.image.WritableImage
jxl.write.WritableImage
Allows an image to be created, or an existing image to be manipulated Note that co-ordinates and dimensions are given in cells, so that if for example the width or height of a cell which the image spans is altered, the image will have a correspondign distortion

Examples of javafx.scene.image.WritableImage

            final SnapshotParameters snapshotParameters = new SnapshotParameters();
            snapshotParameters.setViewport(new Rectangle2D(visualization.getBoundsInParent().getMinX(), visualization.getBoundsInParent().getMinY(),
                                                           visualization.getBoundsInParent().getWidth(),
                                                           contextPane.getLayoutBounds().getHeight() + visualization.getLayoutBounds().getHeight() + partPane.getLayoutBounds().getHeight()
            ));
            WritableImage snapshot = this.snapshot(snapshotParameters, null);
            //pass snapshot to save action
