Namespace: DevExpress.Drawing

Assembly: DevExpress.Drawing.v26.1.dll

NuGet Package: DevExpress.Drawing

Declaration

C#

public static DXImage FromStream(
    Stream stream
)

VB.NET

Public Shared Function FromStream(
    stream As Stream
) As DXImage

Parameters

Name	Type	Description
stream	Stream	A stream that contains data for the image.

Returns

Type	Description
DXImage	The created image.

Remarks

The following code examples create an image object from source:

• To use an image locally:

  using (FileStream source = new FileStream(sourceFile, FileMode.Open))
  {
      using (DXImage image = DXImage.FromStream(source))
      {
          // USE AN IMAGE HERE
      }
  }
  

• To use the image globally, you do not have to dispose of either the stream or the image:

  DXImage image = DXImage.FromStream(new FileStream(sourceFile, FileMode.Open));
  

  Important

  Do not confuse the DXImage class with the DXImage component.
