Question

在基于日志的两种不同情况下，我使用签名组件看到“索引超出范围”异常。我无法在模拟器中重现该问题。这是一个已知问题。请告知ID，没有任何解决方法。

代码：

canvas {
    width: 2500px;
}

SignatureComponent signC = new SignatureComponent();
  signC.addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent e) {
                Image sourceImage = sign.getSignatureImage().scaledSmallerRatio(300, 100);
                Image mute = Image.createImage(sourceImage.getWidth(), sourceImage.getHeight(), 0xffffffff);
                Graphics g = mute.getGraphics();
                g.setAntiAliased(true);
                g.drawImage(sourceImage, 0, 0);
                act.setSignature(mute);
            }
        });

这似乎是SignatureComponent中的错误，我在此处添加了一种解决方法：https://github.com/codenameone/CodenameOne/commit/f402d1b27ade9560cd55db1a104f52e004fe1768

此更改将在今天的更新中。
