Halcon 和 C# 联合编程 - 图像变量的相互转换(HObject、HImage、B...

下面代码是我在搜索 get_image_pointer1 过程中得到，给我带来了一些灵感。

/// <summary>
/// 灰度图像变量 HObject -> Bitmap

public static Bitmap HObject2Bitmap(HObject ho)
{
    try
    {
        HTuple type, width, height, pointer;
        //HOperatorSet.AccessChannel(ho, out ho, 1);
        HOperatorSet.GetImagePointer1(ho, out pointer, out type, out width, out height);
        //himg.GetImagePointer1(out type, out width, out height);

        Bitmap bmp = new Bitmap(width.I, height.I, PixelFormat.Format8bppIndexed);
        ColorPalette pal = bmp.Palette;
        for (int i = 0; i <= 255; i++)
        {
            pal.Entries[i] = Color.FromArgb(255, i, i, i);
        }
        bmp.Palette = pal;
        BitmapData bitmapData = bmp.LockBits(new Rectangle(0, 0, width, height), ImageLockMode.WriteOnly, PixelFormat.Format8bppIndexed);
        int PixelSize = Bitmap.GetPixelFormatSize(bitmapData.PixelFormat) / 8;
        int stride = bitmapData.Stride;
        int ptr = bitmapData.Scan0.ToInt32();
        for (int i = 0; i < height; i++)
        {
            CopyMemory(ptr, pointer, width * PixelSize);
            pointer += width;
            ptr += bitmapData.Stride;
        }

        bmp.UnlockBits(bitmapData);
        return bmp;
    }
    catch (Exception exc)
    {
        return null;
    }
}

代码初步看了下，应该没有问题大问题，核心就是图片的数据指针，然后对应大小转换即可！
