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

/// 

/// 灰度图像 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; } }
