Examples

The following example shows how to create an instance of ColorConvertedBitmap and use it to convert color.

Stream imageStream = new FileStream("tulipfarm.jpg", FileMode.Open, FileAccess.Read, FileShare.Read);
BitmapSource myBitmapSource = BitmapFrame.Create(imageStream);
BitmapFrame myBitmapSourceFrame = (BitmapFrame)myBitmapSource;
ColorContext sourceColorContext = myBitmapSourceFrame.ColorContexts[0];
ColorContext destColorContext = new ColorContext(PixelFormats.Bgra32);
ColorConvertedBitmap ccb = new ColorConvertedBitmap(myBitmapSource, sourceColorContext, destColorContext, PixelFormats.Pbgra32);
Image myImage3 = new Image();
myImage3.Source = ccb;
myImage3.Stretch = Stretch.None;
imageStream.Close();
Dim imageStream As New FileStream("tulipfarm.jpg", FileMode.Open, FileAccess.Read, FileShare.Read)
Dim myBitmapSource As BitmapSource = BitmapFrame.Create(imageStream)
Dim myBitmapSourceFrame As BitmapFrame = CType(myBitmapSource, BitmapFrame)
Dim sourceColorContext As ColorContext = myBitmapSourceFrame.ColorContexts(0)
Dim destColorContext As New ColorContext(PixelFormats.Bgra32)
Dim ccb As New ColorConvertedBitmap(myBitmapSource, sourceColorContext, destColorContext, PixelFormats.Pbgra32)
Dim myImage3 As New Image()
myImage3.Source = ccb
myImage3.Stretch = Stretch.None
imageStream.Close()

Remarks

For XAML usage information, see ColorConvertedBitmap Markup Extension.

ColorConvertedBitmap implements the ISupportInitialize interface to optimize initialization on multiple properties. Property changes can only occur during object initialization. Call BeginInit to signal that initialization has begun and EndInit to signal that initialization has completed. After initialization, property changes are ignored.

ColorConvertedBitmap objects created using the ColorConvertedBitmap(BitmapSource, ColorContext, ColorContext, PixelFormat) constructor are automatically initialized, and property changes are ignored.

A ColorConvertedBitmap is never cached.
