[FIXED] How to save canvas as png file without inform user,

Issue

I want to save my canvas with javafx without implement the showDialog, I can do it with the showDialog but I want to delete it.

    public void exportCanvasToPNG(String fileName) {
        // face = Canvase
        if (face != null) {
            WritableImage img = face.snapshot(new SnapshotParameters(), null);

            FileChooser fChooser = new FileChooser();
            fChooser.setTitle("Sauvegarde preview");
            fChooser.setInitialFileName(fileName);
            fChooser.setInitialDirectory(dir);
            fChooser.getExtensionFilters().add(new FileChooser.ExtensionFilter("Fichier PNG", "*.png"));

            // selectedFile = File
            selectedFile = fChooser.showSaveDialog(stage);

            try {
                if (selectedFile != null) {
                    ImageIO.write(SwingFXUtils.fromFXImage(img, null), "png", selectedFile);
                }
            } catch (IOException e) {
                e.printStackTrace();
            }

        }

    }``

Solution

public void exportCanvasToPNG(String fileName) {
    // face = Canvas
    if (face != null) {
        WritableImage img = face.snapshot(new SnapshotParameters(), null);
        try {
            File outputFile = new File("FaceSnapshot.png");
            ImageIO.write(SwingFXUtils.fromFXImage(img, null), "png", outputFile);
        } catch (IOException e) {
            e.printStackTrace();
        }

    }

}
