Initializes a new instance of the ColorConvertedBitmap class.
Overloads
| ColorConvertedBitmap() |
Initializes a new instance of the ColorConvertedBitmap class. |
| ColorConvertedBitmap(BitmapSource, ColorContext, ColorContext, PixelFormat) |
Initializes a new instance of the ColorConvertedBitmap class by using the specified values. |
ColorConvertedBitmap()
Initializes a new instance of the ColorConvertedBitmap class.
public:
ColorConvertedBitmap();public ColorConvertedBitmap ();Public Sub New ()Remarks
ColorConvertedBitmap implements the ISupportInitialize interface to optimize initialization on multiple properties. To initialize a ColorConvertedBitmap created using this constructor, you must perform property initialization between BeginInit and EndInit calls.
Applies to
ColorConvertedBitmap(BitmapSource, ColorContext, ColorContext, PixelFormat)
Initializes a new instance of the ColorConvertedBitmap class by using the specified values.
public:
ColorConvertedBitmap(System::Windows::Media::Imaging::BitmapSource ^ source, System::Windows::Media::ColorContext ^ sourceColorContext, System::Windows::Media::ColorContext ^ destinationColorContext, System::Windows::Media::PixelFormat format);public ColorConvertedBitmap (System.Windows.Media.Imaging.BitmapSource source, System.Windows.Media.ColorContext sourceColorContext, System.Windows.Media.ColorContext destinationColorContext, System.Windows.Media.PixelFormat format);new System.Windows.Media.Imaging.ColorConvertedBitmap : System.Windows.Media.Imaging.BitmapSource * System.Windows.Media.ColorContext * System.Windows.Media.ColorContext * System.Windows.Media.PixelFormat -> System.Windows.Media.Imaging.ColorConvertedBitmapPublic Sub New (source As BitmapSource, sourceColorContext As ColorContext, destinationColorContext As ColorContext, format As PixelFormat)Parameters
- source
- BitmapSource
The BitmapSource that is converted.
- sourceColorContext
- ColorContext
The ColorContext of the source bitmap.
- destinationColorContext
- ColorContext
The ColorContext of the converted bitmap.
- format
- PixelFormat
The PixelFormat of the converted bitmap.
Examples
The following example shows how to initialize an instance of ColorConvertedBitmap by using the ColorConvertedBitmap(BitmapSource, ColorContext, ColorContext, PixelFormat) constructor.
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
ColorConvertedBitmap objects created using this constructor are automatically initialized. After initialization, property changes are ignored.
