Procedura: creare un nuovo oggetto BitmapSourceHow to: Create a new BitmapSource

In questo esempio viene illustrato come utilizzare il Create metodo BitmapSource per creare un nuovo BitmapSource oggetto.This example demonstrates how to use the Create method of BitmapSource to create a new BitmapSource object.

EsempioExample

// Define parameters used to create the BitmapSource.
PixelFormat pf = PixelFormats.Bgr32;
int width = 200;
int height = 200;
int rawStride = (width * pf.BitsPerPixel + 7) / 8;
byte[] rawImage = new byte[rawStride * height];

// Initialize the image with data.
Random value = new Random();
value.NextBytes(rawImage);

// Create a BitmapSource.
BitmapSource bitmap = BitmapSource.Create(width, height,
    96, 96, pf, null,
    rawImage, rawStride);

// Create an image element;
Image myImage = new Image();
myImage.Width = 200;
// Set image source.
myImage.Source = bitmap;
' Define parameters used to create the BitmapSource.
Dim pf As PixelFormat = PixelFormats.Bgr32
Dim width As Integer = 200
Dim height As Integer = 200
Dim rawStride As Integer = CType((width * pf.BitsPerPixel + 7) / 8, Integer)
Dim rawImage(rawStride * height) As Byte

' Initialize the image with data.
Dim value As New Random()
value.NextBytes(rawImage)

' Create a BitmapSource.
Dim bitmap As BitmapSource = BitmapSource.Create(width, height, 96, 96, pf, Nothing, rawImage, rawStride)

' Create an image element;
Dim myImage As New Image()
myImage.Width = 200
' Set image source.
myImage.Source = bitmap
