Example for using the Image masking and camera capture API's in Codename One

ImageMaskingSample.java

Toolbar.setGlobalToolbar(true);
Form hi = new Form("Rounder", new BorderLayout());
Label picture = new Label("", "Container");
hi.add(BorderLayout.CENTER, picture);
hi.getUnselectedStyle().setBgColor(0xff0000);
hi.getUnselectedStyle().setBgTransparency(255);
Style s = UIManager.getInstance().getComponentStyle("TitleCommand");
Image camera = FontImage.createMaterial(FontImage.MATERIAL_CAMERA, s);
hi.getToolbar().addCommandToRightBar("", camera, (ev) -> {
    try {
        int width = Display.getInstance().getDisplayWidth();
        Image capturedImage = Image.createImage(Capture.capturePhoto(width, -1));
        Image roundMask = Image.createImage(width, capturedImage.getHeight(), 0xff000000);
        Graphics gr = roundMask.getGraphics();
        gr.setColor(0xffffff);
        gr.fillArc(0, 0, width, width, 0, 360);
        Object mask = roundMask.createMask();
        capturedImage = capturedImage.applyMask(mask);
        picture.setIcon(capturedImage);
        hi.revalidate();
    } catch(IOException err) {
        Log.e(err);
    }
});
