Initializes a new instance of the CroppedBitmap class.
Overloads
CroppedBitmap() |
Initializes a new instance of the CroppedBitmap class. |
CroppedBitmap(BitmapSource, Int32Rect) |
Initializes a new instance of the CroppedBitmap class that has the specified Source and SourceRect. |
CroppedBitmap()
Initializes a new instance of the CroppedBitmap class.
public:
CroppedBitmap();
public CroppedBitmap ();
Public Sub New ()
Remarks
CroppedBitmap implements the ISupportInitialize interface to optimize initialization on multiple properties. To initialize a CroppedBitmap created using this constructor, you must perform property initialization between BeginInit and EndInit calls.
Applies to
CroppedBitmap(BitmapSource, Int32Rect)
Initializes a new instance of the CroppedBitmap class that has the specified Source and SourceRect.
public:
CroppedBitmap(System::Windows::Media::Imaging::BitmapSource ^ source, System::Windows::Int32Rect sourceRect);
public CroppedBitmap (System.Windows.Media.Imaging.BitmapSource source, System.Windows.Int32Rect sourceRect);
new System.Windows.Media.Imaging.CroppedBitmap : System.Windows.Media.Imaging.BitmapSource * System.Windows.Int32Rect -> System.Windows.Media.Imaging.CroppedBitmap
Public Sub New (source As BitmapSource, sourceRect As Int32Rect)
Parameters
- source
- BitmapSource
The Source of the new CroppedBitmap instance.
- sourceRect
- Int32Rect
The SourceRect of the new CroppedBitmap instance.
Exceptions
source
is null
.
sourceRect
is outside the boundaries of source
.
Examples
The following example shows how to use CroppedBitmap(BitmapSource, Int32Rect) to initialize a new instance of the CroppedBitmap class.
// Create an Image element.
Image chainImage = new Image();
chainImage.Width = 200;
chainImage.Margin = new Thickness(5);
// Create the cropped image based on previous CroppedBitmap.
CroppedBitmap chained = new CroppedBitmap(cb,
new Int32Rect(30, 0, (int)cb.Width-30, (int)cb.Height));
// Set the image's source.
chainImage.Source = chained;
' Create an Image element.
Dim chainImage As New Image()
chainImage.Width = 200
chainImage.Margin = New Thickness(5)
' Create the cropped image based on previous CroppedBitmap.
Dim chained As New CroppedBitmap(cb, New Int32Rect(30, 0, CType(cb.Width, Integer) - 30, CType(cb.Height, Integer)))
' Set the image's source.
chainImage.Source = chained
Remarks
CroppedBitmap objects created using this constructor are automatically initialized. After initialization, property changes are ignored.
