这个程序实现了一般绘图应用程序所具有的绝大多数功能，并提供了一些额外的辅助功能。可以进行直线图元、椭圆图元、三角形图元、矩形图元等图元的绘制，还可以填充图元，绘制文本，改变线条颜色、类型以及填充方式等。允许对图形的删除、修改、拷贝、剪切、平移、撤销等操作。允许改变图元的颜色、线形、形状等。还有辅助网格功能方便用户进行定位绘制。还有文件格式和数据库支持等功能。对想了解GDI编程的朋友有极大的帮助。-the process of general graphics applications have the most functional, and to provide some additional support functions. Can line of yuan, an oval map billion yuan map triangle, rectangle, etc. Figure billion yuan map drawing, but also filled with graphic elements, text drawing, the lines change color, type and form filling. Graphics allow for the deletion, modification, copying, shear, translation, such as revocation of operation. Figure yuan allowed to change the color, line, shape. Also supporting grid user-friendly features for positioning mapping. There are files and database support capabilities. Right would like to know GDI Programming friends of great help.
