在窗体上拖动图片移动，Delphi源码实现的图像拖曳，感觉不是太灵敏，向右拖动时候稍微感觉好一些，向左拖动很不灵敏，程序还有待改进提高，有兴趣的可下载源码研究。-Drag the image to move on the form, Delphi source code to achieve drag the images did not feel too sensitive, drag to the right when feeling a little better, drag to the left is very sensitive, the program could be improved to improve, interested can download source research.
