Bitmap Constructor (Stream)
Initializes a new instance of the Bitmap class from the specified data stream.
Assembly: System.Drawing (in System.Drawing.dll)
stream does not contain image data or is null.
stream contains a PNG image file with a single dimension greater than 65,535 pixels.
The following code example demonstrates how to load a bitmap from a stream.
This example is designed to be used with Windows Forms. Create a form that contains a PictureBox named PictureBox1. Paste the code into the form and call the InitializeStreamBitmap method from the form's constructor or Load event-handling method.
Private Sub InitializeStreamBitmap() Try Dim request As System.Net.WebRequest = _ System.Net.WebRequest.Create( _ "http://www.microsoft.com//h/en-us/r/ms_masthead_ltr.gif") Dim response As System.Net.WebResponse = request.GetResponse() Dim responseStream As System.IO.Stream = response.GetResponseStream() Dim bitmap2 As New Bitmap(responseStream) PictureBox1.Image = bitmap2 Catch ex As System.Net.WebException MessageBox.Show("There was an error opening the image file. Check the URL") End Try End Sub
