Simple command-line tool for making screenshots (for Windows Vista or later)

Fixed so that the drop shadow of the window frame does not appear.
(ウィンドウフレームのドロップシャドウが映らないように修正した)

To build:

g++ -Wall -Os -mwindows -municode screenshot.cpp -lgdiplus -lDwmapi -o screenshot -static

To reduce the size:

strip screenshot.exe

To run:

screenshot.exe -wh 1e9060a -o screenshot.png
