delphi中用鼠标拖动移动Image控件,delphi drag with the mouse controls mobile Image

本人自己编写，目前为止唯一一个可以用鼠标中键控制图片大小缩放，点击鼠标可以拖拽jpg格式图片的delphi源码，网上独此一家-I have written so far only one mouse button can control the image size scaling, click the mouse to drag the jpg format pictures delphi source, this one line alone

基于Delphi中的图片拖放实例，支持浏览图片，上传图片-Drag and drop images based on examples in Delphi
