Bmp To Mif 转换器

Bmp To Mif 转换器 // (karimov 2005) // This program was originnaly written by one of the ECE241 students to convert an image // supplied in a BMP file into an MIF file format for use with Quartus II. // // This program has recently been modified to work with the new VGA controller used with the DE2 // board. // // What to do: // 1. Create an image in Microsoft paint (or other program). The image must be 160 pixels wide, 120 pixels high and // use 24-bits to represent colour information. // 2. Once you create the image you need, flip it up-side down. Then save the BMP file. (example: foo.bmp) // 3. Run this converter in command prompt using the name of the BMP file you created as a command-line parameter. // For example: // bmp2mif foo.bmp // 4. The program generates two files: // image.colour.mif - an MIF file with 3 bits colour information obtained from the BMP file you supplied // image.mono.mif - an MIF file containing 1 bit of colour for every pixel on the screen. The dot will either be // black or white. // You can change the file names once they are created, but they should still have the .mif extension. // // 5. Copy the proper MIF file to the directory where your design is located and include it in your project. // 6. Change the BACKGROUND_IMAGE parameter of the VgaAdapter to indicate your MIF file. // 7. The COLOR_CHANNEL_DEPTH parameter must be set to 1 to work with the image.colour.mif file. #include #include #define FLIP_INT(c) ((c >> 24) & 0x000000FF) | ((c & 0x00FF0000) >> 8) | ((c & 0x0000FF00) << 8) | ((c & 0x000000FF) <> 8) | ((c & 0x00FF) << 8) typedef struct s_header { unsigned short bfType; unsigned int bfSize; unsigned short reserved1; unsigned short reserved2; unsigned int offset; } t_bmp_header; typedef struct s_bmp_info { unsigned int biSize; unsigned int biWidth; unsigned int biHeight; unsigned short biPlanes; unsigned short biBitCount; unsigned in
