c++读取bmp图片详解。BMP（全称Bitmap）是Windows操作系统中的标准图像文件格式，可以分成两类：设备相关位图（DDB）和设备无关位图（DIB），使用非常广。它采用位映射存储格式，除了图像深度可选以外，不采用其他任何压缩，因此，BMP文件所占用的空间很大。BMP文件的图像深度可选lbit、4bit、8bit及24bit。BMP文件存储数据时，图像的扫描方式是按从左到右、从下到上的顺序。由于BMP文件格式是Windows环境中交换与图有关的数据的一种标准，因此在Windows环境中运行的图形图像软件都支持BMP图像格式。(C++ read BMP pictures detailed. BMP (full name Bitmap) is a standard image file format in the Windows operating system. It can be divided into two categories: device dependent bitmaps (DDB) and device independent bitmaps (DIB), which are very widely used. It uses bit mapped storage format, and does not use any other compression than the image depth, so the BMP file takes up a lot of space. The image depth of the BMP file is optional, Lbit, 4bit, 8bit, and 24bit. When the BMP file stores data, the image is scanned in the order from left to right, from bottom to top. Since the BMP file format is a standard for exchanging data related to graphs in the Windows environment, the graphic image software that runs in the Windows environment supports the BMP image format.)
