ketan Ram Patil 25-Jul-19 9:06am View

DMS means document management system where you can store the documents. and responsive means ui will adjust automatically and display according to the screen size .

Dim rcFrom As New System.Windows.Int32Rect()
rcFrom.X = CInt((rect1.X) * (image1.Source.Width) / (image1.Width))

'Dim BitmapImage As BitmapImage
'BitmapImage = image1.Source
'BitmapImage.StreamSource.Seek(0, System.IO.SeekOrigin.Begin)
