BurageSnap allows you to take a screenshot of a browser game a.k.a ブラゲ [burʌgɛ] in Japanese with just one click. It finds the window with the specified title, recognizes the game screen, and save as a JPEG or PNG file. It can also continuously capture the game screen and save as an animation GIF file. BurageSnap recognizes a large rectangle even with rounded or vague corners surrounded by white pixels as a game screen.
