這篇文章主要介紹了C# 判斷兩張圖片是否一致的快速方法,需要的朋友可以參考下
代碼如下: #region 判斷圖片是否一致 /// <summary> /// 判斷圖片是否一致 /// </summary> /// <param name="img">圖片一</param> /// <param name="bmp">圖片二</param> /// <returns>是否一致</returns> public bool IsSameImg(Bitmap img, Bitmap bmp) { //大小一致 if (img.Width == bmp.Width && img.Height == bmp.Height) { //將圖片一鎖定到內存 BitmapData imgData_i = img.LockBits(new Rectangle(0, 0, img.Width, img.Height), ImageLockMode.ReadOnly, PixelFormat.Format24bppRgb); IntPtr ipr_i = imgData_i.Scan0; int length_i = imgData_i.Width * imgData_i.Height * 3; byte[] imgValue_i = new byte[length_i]; Marshal.Copy(ipr_i, imgValue_i, 0, length_i); img.UnlockBits(imgData_i); //將圖片二鎖定到內存 BitmapData imgData_b = img.LockBits(new Rectangle(0, 0, img.Width, img.Height), ImageLockMode.ReadOnly, PixelFormat.Format24bppRgb); IntPtr ipr_b = imgData_b.Scan0; int length_b = imgData_b.Width * imgData_b.Height * 3; byte[] imgValue_b = new byte[length_b]; Marshal.Copy(ipr_b, imgValue_b, 0, length_b); img.UnlockBits(imgData_b); //長度不相同 if (length_i != length_b) { return false; } else { //循環判斷值 for (int i = 0; i < length_i; i++) { //不一致 if (imgValue_i[i] != imgValue_b[i]) { return false; } } return true; } } else { return false; } } #endregion
