components.qt.showhistogram

class ShowHistogram(**config)[source]

Bases: Transformer, object

Display image hostograms in a Qt window.

The histogram display is normalised so each component uses the full Y-axis range. The X-axis covers the range [0, 256). Values outside this range are counted and the results displayed as raw numbers and percentage of pixels.

Config
`title`	str	Window title.
`log`	bool	Use logarithmic Y axis.

event_loop: alias of QtEventLoop
