    copied!<p>I'm trying to find patches of a certain color on the screen.</p> <p>I am able to find all the pixels on the screen and test the RGB and add the points into an array, but i don't want all the pixels just 1 point for each patch of the color.</p> <p>Here is my code:</p> <pre><code> public static Point[] PixelSearch(Rectangle rect, Color Pixel_Color, int Shade_Variation) { ArrayList points = new ArrayList(); Bitmap RegionIn_Bitmap = new Bitmap(rect.Width, rect.Height, PixelFormat.Format24bppRgb); using (Graphics GFX = Graphics.FromImage(RegionIn_Bitmap)) { GFX.CopyFromScreen(rect.X, rect.Y, 0, 0, rect.Size, CopyPixelOperation.SourceCopy); } BitmapData RegionIn_BitmapData = RegionIn_Bitmap.LockBits(new Rectangle(0, 0, RegionIn_Bitmap.Width, RegionIn_Bitmap.Height), ImageLockMode.ReadWrite, PixelFormat.Format24bppRgb); int[] Formatted_Color = new int[3] { Pixel_Color.B, Pixel_Color.G, Pixel_Color.R }; //bgr unsafe { for (int y = 0; y &lt; RegionIn_BitmapData.Height; y++) { byte* row = (byte*)RegionIn_BitmapData.Scan0 + (y * RegionIn_BitmapData.Stride); for (int x = 0; x &lt; RegionIn_BitmapData.Width; x++) if (row[x * 3] &gt;= (Formatted_Color[0] - Shade_Variation) &amp; row[x * 3] &lt;= (Formatted_Color[0] + Shade_Variation)) //blue if (row[(x * 3) + 1] &gt;= (Formatted_Color[1] - Shade_Variation) &amp; row[(x * 3) + 1] &lt;= (Formatted_Color[1] + Shade_Variation)) //green if (row[(x * 3) + 2] &gt;= (Formatted_Color[2] - Shade_Variation) &amp; row[(x * 3) + 2] &lt;= (Formatted_Color[2] + Shade_Variation)) //red points.Add(new Point(x + rect.X, y + rect.Y)); } } RegionIn_Bitmap.Dispose(); return (Point[])points.ToArray(typeof(Point)); } </code></pre> <p>I call the method like this:</p> <pre><code>points = PixelSearch(Screen.PrimaryScreen.Bounds, Color.FromArgb(255, 0, 0), 15); </code></pre> <p>I sometimes get thousands of results from this and would only like a few. any ideas how i can do this?</p>
