	int height
)

Type: SystemInt32
top

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 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 size of the array must be at least width * height * (bytes per block) / 16. See Bitmap block compression page for more information.
