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

CanvasBitmapGetPixelBytes Method (IBuffer, Int32, Int32, Int32, Int32)

Copies raw byte data for a subregion of the bitmap into the specified buffer.

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

Syntax

public void GetPixelBytes(
	IBuffer buffer,
	int left,
	int top,
	int width,
	int height
)

Remarks

Works on bitmaps of any format.
left, top, width and height are specified in pixels (not DIPs).
For uncompressed texture formats, the capacity of the buffer must be at least 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 capacity of the buffer must be at least width * height * (bytes per block) / 16. See Bitmap block compression page for more information.
