videolib.video.Frame

class Frame(standard, quantization=None, dither=False)

Bases: object

Class defining a frame, either of a video or an image. Supported native color representations: rgb, linear_rgb, bgr, linear_bgr, yuv, linear_yuv, xyz. Access as frame.<color_space>. For all others, use the cvt_color submodule.

Initializer.

Parameters:

• standard (Standard) – Coor standard to which the data conforms.

• quantization (Optional[int]) – Value to which data will be quantized and scaled back to original range.

• dither (Optional[bool]) – Flag denoting whether dithering must be applied after quantization.

Methods

quantize	Quantize value to have quantization number of levels, while occupying the same input range.
show	Plot image using matplotlib.

Attributes

height	Height of the Frame
primaries	Color primaries of the Frame's standard
width	Width of the Frame

property height: int

Parameters:

value (Union[int, ndarray]) – Value to be quantized.

Returns:

Quantized value, if quantization attribute is specified.

Return type:

show(interactive=False, **kwargs)

Plot image using matplotlib.

Parameters:

• interactive (Optional[bool]) – Run matplotlib in interactive mode.
