Features and interfaces in Windows, bringing all to imitate the drawing board, such as interface screenshot. The main features include: hand-painted lines, simple graphics, text input, drag and drop block, duplicate revoked, screen zoom, open the Save picture files, the other in order to directly from the database or XML access picture also provides a survival from the Base64 encoding Photos from the interface, the other also drawing board and achieve the same effect toolbox and paint boxes.)
