void pav::lib::visualizer::VisualizerAbstract::drawTo ( PApplet applet ) throws PAVException [inline]

Sets the PApplet to draw to. Must be called before process().

Parameters:

applet

Where to draw to. Must not be null

Exceptions:

PAVException

If the visualizer does not work with this applet

Implements pav::lib::visualizer::Visualizer.

Reimplemented in pav::lib::visualizer::Boxes, and pav::lib::visualizer::Bubbles.

float [] pav::lib::visualizer::VisualizerAbstract::getArea ( ) [inline, protected]

Returns the area this visualizer may use. The area is specified by and array containing 4 values:

[0] - Low x-coordinate [1] - Low y-coordinate [2] - High x-coordinate [3] - High y-coordinate

If the area is specified relative (see setArea()) but no PApplet object is available, all values will be 0.

Returns:: The erea

void pav::lib::visualizer::VisualizerAbstract::setArea	(	float	x1,
		float	y1,
		float	x2,
		float	y2,
		boolean	relative
	)			`[inline]`

Sets the area that can be used by this visualizer. If relative is set to false the visualizer will use the given values as its boundary, independent of the size of the PApplet. If relative is true, the values must be in the range [0,1] and represent an area relative to the size of the PApplet. Processings coordinate system is used, so (0,0) is the top left pixel.

Parameters:

	x1	Must be >= 0 and <= 1 if relative is true
	y1	Must be >= 0 and <= 1 if relative is true
	x2	Must be > x1 and <= 1 if relative is true
	y2	Must be > y1 and <= 1 if relative is true
	relative	Whether or not the values are relative

Implements pav::lib::visualizer::Visualizer.

void pav::lib::visualizer::VisualizerAbstract::setColor	(	float[]	thresholds,
		int[]	colors,
		int	mode
	)			`[inline]`

Sets the colors to interpolate between when drawing this visualizer. How a visualizer uses the colors specified is not defined. They might not be used at all.

Parameters:

	thresholds	The relative thresholds to use. Values must be between 0 and 1 and sorted. The first element must be 0, the last 1. Must be of same length as colors
	colors	The The colors to use. Must be of same length as thresholds
	mode	The color mode to use. Must be either PApplet.RGB or PApplet.HSB

Implements pav::lib::visualizer::Visualizer.

Reimplemented in pav::lib::visualizer::Boxes.

void pav::lib::visualizer::VisualizerAbstract::setColor	(	int	a,
		int	b,
		int	mode
	)			`[inline]`

Sets two colors to interpolate between when drawing this visualizer. How a visualizer uses the colors specified is not defined. They might not be used at all.

Parameters:
