Copies the bitmap pixel data.

Overloads

CopyPixels(Array, Int32, Int32)	Copies the bitmap pixel data into an array of pixels with the specified stride, starting at the specified offset.
CopyPixels(Int32Rect, Array, Int32, Int32)	Copies the bitmap pixel data within the specified rectangle into an array of pixels that has the specified stride starting at the specified offset.
CopyPixels(Int32Rect, IntPtr, Int32, Int32)	Copies the bitmap pixel data within the specified rectangle.

CopyPixels(Array, Int32, Int32)

Public Overridable Sub CopyPixels (pixels As Array, stride As Integer, offset As Integer)

Parameters

pixels: Array

The destination array.

stride: Int32

The stride of the bitmap.

offset: Int32

The pixel location where copying starts.

Attributes: SecurityCriticalAttribute

Applies to

CopyPixels(Int32Rect, Array, Int32, Int32)

Copies the bitmap pixel data within the specified rectangle into an array of pixels that has the specified stride starting at the specified offset.

public:
 virtual void CopyPixels(System::Windows::Int32Rect sourceRect, Array ^ pixels, int stride, int offset);

[System.Security.SecurityCritical]
public virtual void CopyPixels (System.Windows.Int32Rect sourceRect, Array pixels, int stride, int offset);

Public Overridable Sub CopyPixels (sourceRect As Int32Rect, pixels As Array, stride As Integer, offset As Integer)

Parameters

sourceRect: Int32Rect

The source rectangle to copy. An Empty value specifies the entire bitmap.

pixels: Array

The destination array.

stride: Int32

The stride of the bitmap.

offset: Int32

The pixel location where copying begins.

Attributes: SecurityCriticalAttribute

Remarks

An empty sourceRect value (specified as all zeros) copies the entire bitmap.

Applies to

CopyPixels(Int32Rect, IntPtr, Int32, Int32)

Copies the bitmap pixel data within the specified rectangle.

public:
 virtual void CopyPixels(System::Windows::Int32Rect sourceRect, IntPtr buffer, int bufferSize, int stride);

[System.Security.SecurityCritical]
public virtual void CopyPixels (System.Windows.Int32Rect sourceRect, IntPtr buffer, int bufferSize, int stride);

buffer: IntPtr
nativeint

A pointer to the buffer.

bufferSize: Int32

The size of the buffer.

stride: Int32

The stride of the bitmap.

Attributes: SecurityCriticalAttribute

Remarks
