在判断图形A是否在图形B里存在 中,有个新手不懂的问题,请指教
C# 判断图形A是否在图形B里存在 并返回所在位置的坐标
做了下测试
Bitmap Image1 = (Bitmap)Image.FromFile(@"c:/1.BMP");
Bitmap Image2 = Image1.Clone(new Rectangle(20, 20, 50, 50), Image1.PixelFormat);
Point _Point= Zgke.MyImage.Panit.MyPanit.GetImageContains(Image1, Image2,0);
MessageBox.Show(_Point.ToString());
返回的坐标是20,20
下面是全部代码
/// <summary>
/// 判断图形里是否存在另外一个图形 并返回所在位置
/// </summary>
/// <param name="p_SourceBitmap">原始图形</param>
/// <param name="p_PartBitmap">小图形</param>
/// <param name="p_Float">溶差</param>
/// <returns>坐标</returns>
public static Point GetImageContains(Bitmap p_SourceBitmap, Bitmap p_PartBitmap,int p_Float)
{
int _SourceWidth = p_SourceBitmap.Width;
int _SourceHeight = p_SourceBitmap.Height;
int _PartWidth = p_PartBitmap.Width;
int _PartHeight = p_PartBitmap.Height;
Bitmap _SourceBitmap = new Bitmap(_SourceWidth, _SourceHeight);
Graphics _Graphics = Graphics.FromImage(_SourceBitmap);
_Graphics.DrawImage(p_SourceBitmap, new Rectangle(0, 0, _SourceWidth, _SourceHeight));
_Graphics.Dispose();
BitmapData _SourceData = _SourceBitmap.LockBits(new Rectangle(0, 0, _SourceWidth, _SourceHeight), ImageLockMode.ReadWrite, PixelFormat.Format32bppArgb);
