class Threshold – Threshold Object

The threshold object is an attrtuple returned by histogram.get_threshold().

Grayscale thresholds have one channel; use value. RGB565 thresholds have three channels; use l_value, a_value, and b_value.

Fields are accessible by name (threshold.value) or by index (threshold[0]). It has no public constructor.

class image.threshold

Please call histogram.get_threshold() to create this object.

value() → int

Returns the grayscale threshold value (0 - 255).

Also accessible as threshold[0].

l_value() → int

Returns the RGB565 LAB L channel threshold value (0 - 100).

Also accessible as threshold[1].

a_value() → int

Returns the RGB565 LAB A channel threshold value (-128 - 127).

Also accessible as threshold[2].

b_value() → int

Returns the RGB565 LAB B channel threshold value (-128 - 127).

Also accessible as threshold[3].
