CanvasBitmap.GetPixelBytes Method (Int32, Int32, Int32, Int32)

CanvasBitmapGetPixelBytes Method (Int32, Int32, Int32, Int32)

Returns an array of raw byte data for a subregion of the bitmap.

Namespace: Microsoft.Graphics.Canvas
Assembly: Microsoft.Graphics.Canvas (in Microsoft.Graphics.Canvas.dll) Version: 0.0.0.0

Syntax

public byte[] GetPixelBytes(
	int left,
	int top,
	int width,
	int height
)

Type: Byte

Remarks

Works on bitmaps of any format.
left, top, width and height are specified in pixels (not DIPs).
For uncompressed texture formats, the size of the array is width * height * (bytes per pixel). The number of bytes per pixel is determined by Format. For a CanvasBitmap with the default format of DirectXPixelFormat.B8G8R8A8UintNormalized this is 4.
For block compressed texture formats, the size of the array is width * height * (bytes per block) / 16. See Bitmap block compression page for more information.
