FreeImage图像格式转换

由于opencv支持的图像格式有限，为了弥补这个不足，使用FreeImage进行格式转换。

基于磁盘文件的图像格式转换：

int main()
{
    FreeImage_Initialise();

    const char* srcImagePath = "E:/Desktop/01.tif";
    const char* dstImagePath = "E:/Desktop/01.png";

    int srcImageFormat = FreeImage_GetFIFFromFilename(srcImagePath);
    FIBITMAP *dib = FreeImage_Load(static_cast<FREE_IMAGE_FORMAT>(srcImageFormat), srcImagePath);
    if (dib == NULL)
    {
        cout << "图像加载失败" << endl;
        return 0;
    }

    unsigned int width = FreeImage_GetWidth(dib);    
    unsigned int height = FreeImage_GetHeight(dib);

    int dstImageFormat = FreeImage_GetFIFFromFilename(dstImagePath);
    if (!FreeImage_Save(static_cast<FREE_IMAGE_FORMAT>(dstImageFormat), dib, dstImagePath))
    {
        cout << "图像保存失败" << endl;
        return 0;
    }

    FreeImage_DeInitialise();

    return 0;
}
