ToStream

ImageData.ToStream method

Creates and returns a stream that contains the image bytes.

public Stream ToStream()

Remarks

If the image bytes are stored in the shape, creates and returns a MemoryStream object.

If the image is linked and stored in a file, opens the file and returns a FileStream object.

If the image is linked and stored in an external URL, downloads the file and returns a MemoryStream object.

Is it the responsibility of the caller to dispose the stream object.

Examples

Shows how to create an image file from a shape’s raw image data.

Document imgSourceDoc = new Document(MyDir + "Images.docx");
Shape imgShape = (Shape) imgSourceDoc.GetChild(NodeType.Shape, 0, true);

Assert.True(imgShape.HasImage);

// ToByteArray() returns the array stored in the ImageBytes property.
Assert.AreEqual(imgShape.ImageData.ImageBytes, imgShape.ImageData.ToByteArray());

// Save the shape's image data to an image file in the local file system.
using (Stream imgStream = imgShape.ImageData.ToStream())
{
    using (FileStream outStream = new FileStream(ArtifactsDir + "Drawing.GetDataFromImage.png",
        FileMode.Create, FileAccess.ReadWrite))
    {
        imgStream.CopyTo(outStream);
    }
}
