Methods

__init__(data, width, height, bit_depth, ...)
pixels()	Return pixels as a standard-library array (native-endian for 16-bit frames).
save_pgm(path)	Save the raw frame as a portable graymap image.
save_png(path[, maximum_size])	Save the raw frame as a browser-compatible grayscale PNG image.
sharpness([sample_step])	Variance of a Laplacian over the central image region.
statistics()	Return (minimum, maximum, mean) without requiring NumPy.
to_numpy()	Return a height x width NumPy view of the frame.
to_png_bytes([maximum_size])	Encode the frame as a PNG, optionally downsampling it to a bounding square.

Parameters:

• data (bytes)

• width (int)

• height (int)

• bit_depth (int)

• exposure_ms (float)

• gain (float)

• captured_at (float)
