当我们使用相机SDK采集图像时，得到的往往是Bitmap图像，在这给大家分享一下自己写的Bitmap如何转换成HImage的代码，希望能帮到大家。

    /// <summary>     /// 彩色图Bitmap转换成HImage     /// </summary>     /// <param name="bImage"></param>     /// <returns></returns>     HImage Bitmap2HImage_24(Bitmap bImage)     {         Bitmap bImage24;         BitmapData bmData = null;         Rectangle rect;         IntPtr pBitmap;         IntPtr pPixels;         HImage hImage = new HImage();         rect = new Rectangle(0, 0, bImage.Width, bImage.Height);         bImage24 = new Bitmap(bImage.Width, bImage.Height, System.Drawing.Imaging.PixelFormat.Format24bppRgb);        System.Drawing.Graphics g = System.Drawing.Graphics.FromImage(bImage24);         g.DrawImage(bImage, rect);         g.Dispose();         bmData = bImage24.LockBits(rect, ImageLockMode.ReadOnly, System.Drawing.Imaging.PixelFormat.Format24bppRgb);         pBitmap = bmData.Scan0;         pPixels = pBitmap;         hImage.GenImageInterleaved(pPixels, "bgr", bImage.Width, bImage.Height, -1, "byte", 0, 0, 0, 0, -1, 0);         bImage24.UnlockBits(bmData);         return hImage;     }     /// <summary>     /// Bitmap转换成HImage     /// </summary>     /// <param name="bImage"></param>     /// <returns></returns>     HImage Bitmap2HImage_8(Bitmap bImage)     {         Bitmap bImage8;         BitmapData bmData = null;         Rectangle rect;         IntPtr pBitmap;         IntPtr pPixels;         HImage hImage = new HImage();         rect = new Rectangle(0, 0, bImage.Width, bImage.Height);         bImage8 = new Bitmap(bImage.Width, bImage.Height, System.Drawing.Imaging.PixelFormat.Format8bppIndexed);         System.Drawing.Graphics g = System.Drawing.Graphics.FromImage(bImage8);         g.DrawImage(bImage, rect);         g.Dispose();         bmData = bImage8.LockBits(rect, ImageLockMode.ReadOnly, System.Drawing.Imaging.PixelFormat.Format8bppIndexed);         pBitmap = bmData.Scan0;         pPixels = pBitmap;         hImage.GenImage1("byte", bImage.Width, bImage.Height, pPixels);         bImage8.UnlockBits(bmData);         return hImage;     }
