Error cannot declare instance members in a static class (in searchBitmap)

    Question

  • i get this error

    public static Rectangle searchBitmap( Bitmap smallBmp, Bitmap bigBmp) { BitmapData smallData = smallBmp.LockBits(new Rectangle(0, 0, smallBmp.Width, smallBmp.Height), System.Drawing.Imaging.ImageLockMode.ReadOnly, System.Drawing.Imaging.PixelFormat.Format24bppRgb); BitmapData bigData = bigBmp.LockBits(new Rectangle(0, 0, bigBmp.Width, bigBmp.Height), System.Drawing.Imaging.ImageLockMode.ReadOnly, System.Drawing.Imaging.PixelFormat.Format24bppRgb); int smallStride = smallData.Stride; int bigStride = bigData.Stride; int bigWidth = bigBmp.Width; int bigHeight = bigBmp.Height - smallBmp.Height + 1; int smallWidth = smallBmp.Width * 3; int smallHeight = smallBmp.Height; Rectangle location = Rectangle.Empty; int margin = Convert.ToInt32(255.0 * 0); unsafe { byte* pSmall = (byte*)(void*)smallData.Scan0; byte* pBig = (byte*)(void*)bigData.Scan0; int smallOffset = smallStride - smallBmp.Width * 3; int bigOffset = bigStride - bigBmp.Width * 3; bool matchFound = true; for (int y = 0; y < bigHeight; y++) { for (int x = 0; x < bigWidth; x++) { byte* pBigBackup = pBig; byte* pSmallBackup = pSmall; //Look for the small picture. for (int i = 0; i < smallHeight; i++) { int j = 0; matchFound = true; for (j = 0; j < smallWidth; j++) { //With tolerance: pSmall value should be between margins. int inf = pBig[0] - margin; int sup = pBig[0] + margin; if (sup < pSmall[0] || inf > pSmall[0]) { matchFound = false; break; } pBig++; pSmall++; } if (!matchFound) break; //We restore the pointers. pSmall = pSmallBackup; pBig = pBigBackup; //Next rows of the small and big pictures. pSmall += smallStride * (1 + i); pBig += bigStride * (1 + i); } //If match found, we return. if (matchFound) { location.X = x; location.Y = y; location.Width = smallBmp.Width; location.Height = smallBmp.Height; break; } //If no match found, we restore the pointers and continue. else { pBig = pBigBackup; pSmall = pSmallBackup; pBig += 3; } } if (matchFound) break; pBig += bigOffset; } } bigBmp.UnlockBits(bigData); smallBmp.UnlockBits(smallData); return location; }
