有压缩格式的Bitmap BMP图像显示调色板数据和图像数据

  • 参考文章
  • 一、测试代码
  • 二、测试结果
  • 三、调色板数据
  • 四、图像数据

参考文章

  • Bitmap(BMP)图像信息验证
  • Bitmap(BMP)图像信息分析主要说明带压缩的形式

一、测试代码

在这里插入图片描述

{
    u32 ColorPaletteTable[256]  = {0};

    /* 设置文件指针偏移 */

    }

    /* 读取调色板信息 */
    if (fread(ColorPaletteTable, (BitMapInfo.InfoHeader.ColorPalette * 4), 1, pImgFileHandler))

    /* 设置文件指针偏移 */
    if (fseek(pImgFileHandler, BitMapInfo.FileHeader.ImgDataOffset, SEEK_SET))
    {
        printf("Set Offset Error.....2\r\n");
        while (1);
    }

    /* 读取图像数据 */
    if (fread(ImageColorData, BitMapInfo.InfoHeader.ImgDataSize, 1, pImgFileHandler))
    {
        /* 显示图像数据 */
        printf("Color Data Table Info ==> Start:%-5d Size:%-5u\r\n", BitMapInfo.FileHeader.ImgDataOffset, BitMapInfo.InfoHeader.ImgDataSize);
        vShow_ColorData_Table(ImageColorData, BitMapInfo.InfoHeader.ImgDataSize);

    /* 关闭文件 */
    if (pImgFileHandler)
    {
        fclose(pImgFileHandler);
    }

    printf("\r\n\r\n");
    printf("Compiler Date : %s  %s\r\n", __DATE__, __TIME__);
    while(1);
    return 0;
}
