Some basic concepts of Device Dependent Bitmap ( DDB ) and Device Independent Bitmap(DIB) ( DIB ) are introduced. 介绍了设备相关位图(DDB)、设备无关位图(DIB)的基本概念。
Instead of using file for image's buffer and exchange, this article uses memory buffer directly to create Device Independent Bitmap(DIB) ( DIB ) and send it in remote workstation, and show the image in console the same way. 本文对利用文件进行图像缓冲和交换的方式进行了改进,在远程工作站利用内存缓冲区直接进行设备无关位图(DIB)的建立且进行传送,并在控制台直接显示内存缓冲区中的DIB。
Two different methods in getting lattice information for LED screen displays are introduced : one is to get Device Independent Bitmap(DIB) by intercepting computer screen, the other is the usage of Chinese character library. These two methods are implemented by Visual C + +. 本文介绍了两种不同的获得LED显示屏显示所需的点阵信息的方法:运用屏幕截取获得设备无关位图方法和汉字字库方法,并通过Visualc++编程实现。
