Member Function Documentation

◆ do_fft()

bool analyzer::do_fft	(	int	subindex,
		int	points ) const

◆ draw()

		float *	data,
		int	points,

		int	subindex,
		int	phase,
		float *	data,
		int	points,
		cairo_iface *	context,
		int *	mode ) const

virtual

Obtain subindex'th graph of parameter 'index'

Parameters

index	parameter/graph number (usually tied to particular plugin control port)
subindex	graph number (there may be multiple overlaid graphs for one parameter, eg. for monosynth 2x12dB filters)
phase	0 if in cache phase or 1 if in realtime phase
data	buffer for normalized output values
points	number of points to fill
context	cairo context to adjust (for multicolour graphs etc.)

Return values

true	graph data was returned; subindex+1 graph may or may not be available
false	graph data was not returned; subindex+1 graph does not exist either

Reimplemented from calf_plugins::frequency_response_line_graph.

		std::string &	legend,
		cairo_iface *	context ) const

virtual

Obtain subindex'th dot of parameter 'index'

Parameters

index	parameter/dot number (usually tied to particular plugin control port)
subindex	dot number (there may be multiple dots graphs for one parameter)
phase	0 if in cache phase or 1 if in realtime phase

Reimplemented from calf_plugins::frequency_response_line_graph.

virtual

Return which layers need to be redrawn in the next GTK drawing cycle

Parameters

index	Parameter/graph identifier (usually tied to particular plugin control port)
generation	The overall amount of drawing cycles since the last full refresh of all surfaces
layers	Bitmask defining the layers to be redrawn (see layers_flags above)

Return values

true	there's at least one layer to be redrawn; false nothing to draw in this cycle

Reimplemented from calf_plugins::frequency_response_line_graph.
