bmp转Hobject

bmp转Hobject基本代码

public void Bitmap2HObjectBpp8(Bitmap SrcImage, out HObject image) { try { Point po = new Point(0, 0); Size so = new Size(SrcImage.Width, SrcImage.Height);//template.Width, template.Height Rectangle ro = new Rectangle(po, so); Bitmap DstImg = new Bitmap(SrcImage.Width, SrcImage.Height, PixelFormat.Format8bppIndexed); DstImg = SrcImage.Clone(ro, PixelFormat.Format8bppIndexed); Rectangle rect = new Rectangle(0, 0, DstImg.Width, DstImg.Height); BitmapData srcBmpData = DstImg.LockBits(rect, ImageLockMode.ReadOnly, PixelFormat.Format8bppIndexed); HOperatorSet.GenImage1(out image, "byte", DstImg.Width, DstImg.Height, srcBmpData.Scan0); DstImg.UnlockBits(srcBmpData); } catch (Exception ex) { image = null; } }
