Creates a new instance of SubSampler

Method Detail

getDescription

public static java.lang.String getDescription()

getFilterState

public java.lang.Object getFilterState()

Description copied from class: EventFilter

should return the filter state in some useful form

Specified by:

getFilterState in class EventFilter

resetFilter

public void resetFilter()

Description copied from class: EventFilter

should reset the filter to initial state

Specified by:

resetFilter in class EventFilter

initFilter

public void initFilter()

Description copied from class: EventFilter

this should allocate and initialize memory: it may be called when the chip e.g. size parameters are changed after creation of the filter

Specified by:

initFilter in class EventFilter

getBits

public int getBits()

setFilterEnabled

public void setFilterEnabled(boolean yes)

Description copied from class: EventFilter2D

Resets the filter

Overrides:

setFilterEnabled in class EventFilter2D

Parameters:

yes - true to reset

setBits

public void setBits(int bits)

Sets the subsampler subsampling shift.

Parameters:

bits - the number of bits to subsample by, e.g. bits=1 divides by two

filterPacket

public EventPacket filterPacket(EventPacket in)

Description copied from class: EventFilter2D

Subclasses implement this method to define custom processing.

Specified by:

filterPacket in class EventFilter2D

Parameters:

in - the input packet

Returns:

the output packet
