Constructor & Destructor Documentation

SeqGradRamp::SeqGradRamp	(	const STD_string &	object_label,
		channelNo	gradchannel,
		float	initgradstrength,
		float	finalgradstrength,
		double	timestep,
		rampType	type = linear,
		float	steepnessfactor = 1.0,
		bool	reverse = false
	)

Constructs a gradient ramp labeled 'object_label' with the following properties:

• gradchannel: The channel this object should be played out
• initgradstrength: The initial gradient strength, i.e. the strength at the beginning of the ramp
• finalgradstrength: The final gradient strength, i.e. the strength at the end of the ramp
• timestep: The time between adjecent points of the ramp
• type: The shape for the ramp
• steepnessfactor: This parameter in the range of ]0,1] determines the relative rising speed of the gradient strength, i.e. with 1 the gradients are switched as fast as possible
• reverse: Reverse ramp calculation (only relevant for asymmetric ramps)

SeqGradRamp::SeqGradRamp	(	const STD_string &	object_label,
		channelNo	gradchannel,
		double	gradduration,
		float	initgradstrength,
		float	finalgradstrength,

		rampType	type = linear,
		bool	reverse = false
	)

Constructs a gradient ramp labeled 'object_label' with the following properties:

• finalgradstrength: The final gradient strength, i.e. the strength at the end of the ramp
• timestep: The time between adjecent points of the ramp
• type: The shape for the ramp
• reverse: Reverse ramp calculation (only relevant for asymmetric ramps)
