彩色 Bitmap转换HObject图像
之前已有的代码是这样的

public static HImage Bitmap2HImage_24(Bitmap bImage)
        {
            lock (m_lock)
            {
                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;
            }
        }

但是发现有问题，变换的图像十分异常，

后来查找原因，分析原因，发现是因为Bitmap4字节对齐，非4的整数倍宽度的图像，后面会补0来达到4的倍数。如图像width=202，每行202个字节，实际内存每行后面会补两个字节，宽度变为204个字节。所以重新修改转换代码，在每个末尾进行添加，这部分添加完毕后，经过测试，OK
代码如下

public static void Bmp2HObject3(Bitmap bmp, out HObject image)
        {
            try
            {
                Rectangle rect = new Rectangle(0, 0, bmp.Width, bmp.Height);
                BitmapData srcBmpData = bmp.LockBits(rect, ImageLockMode.ReadOnly, PixelFormat.Format24bppRgb);

                byte[] r = new byte[srcBmpData.Height * srcBmpData.Width];
                byte[] g = new byte[srcBmpData.Height * srcBmpData.Width];
                byte[] b = new byte[srcBmpData.Height * srcBmpData.Width];

                IntPtr ptr1 = Marshal.UnsafeAddrOfPinnedArrayElement(r, 0);
                IntPtr ptr2 = Marshal.UnsafeAddrOfPinnedArrayElement(g, 0);
                IntPtr ptr3 = Marshal.UnsafeAddrOfPinnedArrayElement(b, 0);

                unsafe
                {
                    byte* pIn = (byte*)(srcBmpData.Scan0.ToPointer());
                    for (int y = 0; y < srcBmpData.Height; y++)  //列扫描
                    {
                        for (int x = 0; x < srcBmpData.Width; x++)   //行扫描
                        {
                            int index = y * srcBmpData.Width + x;
                            r[index] = pIn[0];
                            g[index] = pIn[1];
                            b[index] = pIn[2];
                            pIn += 3;
                        }
                        pIn += srcBmpData.Stride - srcBmpData.Width * 3;
                    }
                }
                HOperatorSet.GenImage3(out image, "byte", srcBmpData.Width, srcBmpData.Height, new HTuple(ptr3), new HTuple(ptr2), new HTuple(ptr1));
                bmp.UnlockBits(srcBmpData);

            }
            catch (Exception ex)
            {
                image = null;
            }
        }
