我正在尝试捕获所有笔数据：触摸，某一点的压力，触摸坐标...
有什么建议么？
SigCtl sigCtl = new SigCtl();
DynamicCapture dc = new DynamicCapture();
int rc = dc.capture(sigCtl, "who", "why", null, null);
if(rc == 0) {
System.out.println("signature captured successfully");
String fileName = "sig1.png";
SigObj sig = sigCtl.signature();
sig.extraData("AdditionalData", "CaptureImage.java Additional Data");
int flags = SigObj.outputFilename | SigObj.color32BPP | SigObj.encodeData;
sig.renderBitmap(fileName, 200, 150, "image/png", 0.5f, 0xff0000, 0xffffff, 0.0f, 0.0f, flags );
}
