应该可做，一定要在WORD上做吗？
Snipping Tool 是一个截屏工具，好象不是你想要的。你是想画出不规则地的边界线。
Snipping Tool is a
screenshooting utility included in
Windows Vista and later. It can take screenshots of an open
window, rectangular
areas, a free-form area, or the entire screen. Snips can then be annotated using a mouse or a
tablet, stored as an image file (
PNG,
GIF, or
JPEG file) or an
MHTML file, or
e-mailed. Snipping Tool allows for basic image editing of the snapshot, with different colored pens, an eraser, and a highlighter.
