Bitmap Constructor (Stream)

 

Initializes a new instance of the Bitmap class from the specified data stream.

Namespace:   System.Drawing
Assembly:  System.Drawing (in System.Drawing.dll)

new : 
        stream:Stream -> Bitmap

Parameters

stream
Type: System.IO.Stream

The data stream used to load the image.

Exception Condition
System.ArgumentException

stream does not contain image data or is null.

-or-

stream contains a PNG image file with a single dimension greater than 65,535 pixels.

You must keep the stream open for the lifetime of the Bitmap.

Due to a limitation of the GDI+ decoder, an System.ArgumentException is thrown if you construct a bitmap from 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.
