Detailed Description

The ImageFrame class provides storage and manipulation of frames (multiplanar images).

Constructor & Destructor Documentation

__init__()

def __init__	(		self,
			format = Simd.FrameFormat.Empty,
			width = 0,
			height = 0,
			timestamp = 0.0,
			yuvType = YuvType.Unknown
	)

Creates a new frame.

Parameters

format	- a frame format.
width	- a frame width.
height	- a frame height.
timestamp	- a timestamp of created frame.
yuvType	- a YUV format type of created frame.

Member Function Documentation

	)

Recreates the imagee.

Parameters

format	- a new frame format.
width	- a new frame width.
height	- a new frame height.
yuvType	- a new frame YUV format type.
