From source file:net.rptools.tokentool.controller.TokenTool_Controller.java

@FXML
void compositeTokenPane_OnScroll(ScrollEvent event) {
    // if event is touch enabled, skip this as it will be handled by onZoom & onRotate handlers
    if (event.isDirect())
        return;/*from   w ww .  ja v  a  2  s .  co m*/

    if (event.isShiftDown()) {
        // Note: OK, this is stupid but on Windows shift + mousewheel returns X delta but on Ubuntu it returns Y delta...
        double delta = event.getDeltaY();
        if (delta == 0)
            delta = event.getDeltaX();

        Double r = portraitImageView.getRotate() + delta / 20;

        if (r < -360d || r > 360d)
            r = 0d;

        portraitImageView.setRotate(r);
    } else {
        Double scale = portraitImageView.getScaleY() * Math.pow(1.001, event.getDeltaY());

        portraitImageView.setScaleX(scale);
        portraitImageView.setScaleY(scale);
    }

    event.consume();
