BMP format BMP is short for bitmap. It is a standard image file format in windows and can be supported by multiple Windows applications. With the popularity of the Windows operating system and the development of a wide range of Windows applications, the BMP bitmap format is widely used. This format is characterized by rich image information and almost no compress

Common image file formats (bitmaps)Almost all image files use their own simplified format name as the file extension. From the extension you can know what format this image is stored in, and what software should be used to read/write.One, BMP format:This is a hardware device-independent image file format that is very widely used. It uses the bit map storage format, in addition to the image depth optional, does not adopt any other compression, therefor

XnView Browser: Tools-Batch conversion, configuration, output can export the bat script, the script is used Nconvert.exe here can be bulk conversion folder including subfolders, but not only the specified format (BMP format);So write a bat yourself. @rem 作用：把文件夹下的所有的bmp文件转成jpg格式;nconvert的命令语法是从XnView导出的; @rem 用法： @rem 其他： @rem 2015/12/20 周日 14:34:30.37 @echo offSetLocal EnableDelayEdexpans

I used the iimage interface in the project and found that the function is very powerful. Now I feel that the only drawback is the speed problem. I had to handle many format pictures and write the encoding/decoding by myself, I wrote a BMP file, because the BMP RGB data is well read, and it is easy to save the BMP file. The encoding and decoding of compressed file

The following code is from nehe, based on the framework of Lesson 1: Http://download.csdn.net/source/1907052 1. define a global variable to store the BMP file: Gluint texture [1]; // stores a texture 2. Define two functions to load the BMP file: /* 3. Load BMP in initgl (glvoid) and enable texture ing: // Call the texture loading subroutine 4. Draw a quadril

Post a code memo about mutual conversion between Avi and BMP Code can be found on the Internet. I can run it on the console. Pay attention to the order of header files, and it is easy to report errors. This code is used to disassemble an AVI video into a BMP frame. It is applicable to 24-Bit Bitmap, 8-bit, or other bmp formats that are useful for color palette
