Taking screen capture of Automation Element – TestStak.White

Hi There might be need where we want to take screenshot of particular automation element instead of the entire desktop or entire app.

Here is one way, that we can do that. I hare written general routine for getting the screen capture of the automation element.

public static void takeScreenShot(TestStack.White.UIItems.UIItem b)
 String path;
 Rect bounds = b.Bounds;

//getting values from Rect
 double h = bounds.Height;
 double w = bounds.Width;
 double x = bounds.X;
 double y = bounds.Y;

 //gettomg ramdom number, can change it to date time or somehting meaningful
 Random rndm = new Random();
 //this will generate randomnumber between 1 to 10,000
 int random = rndm.Next(10000);

//getting current directory
 path = System.AppDomain.CurrentDomain.BaseDirectory;
 //replaceing the bin and debug as BaseDirectory will return this
 path = path.Replace("\\bin\\Debug","");
 //creating path with random integer
 path = path + "results\\Screenshot_" + random + ".jpg";

//logic for creating
 //creating equalent in System.Drawing
 //Source point
 System.Drawing.Point p = new System.Drawing.Point(Convert.ToInt32(x), Convert.ToInt32(y));
 //Destination point
 System.Drawing.Point p2 = new System.Drawing.Point(0, 0);

//Creating Rectangle from Rect
 System.Drawing.Rectangle rect = new Rectangle(p.X, p.Y, Convert.ToInt32(w), Convert.ToInt32(h));

//Creating bitmap with desired height and width
 Bitmap bitmap = new Bitmap(rect.Width, rect.Height);

 Graphics g = Graphics.FromImage(bitmap);
 //Coping screen where automation element is present (p) to destnation point on the image (0,0)
 g.CopyFromScreen(p, p2, rect.Size);
 //Saving image
 bitmap.Save(path, ImageFormat.Jpeg);
 catch (Exception e)
