Public Slots
void	slotNewParameters (ColorFilterMode colorFilterMode, double low, double high)
	Start processing with a new set of parameters. Any ongoing processing is interrupted when m_filterMode changes.

Signals
void	signalTransferPiece (int xLeft, QImage image)
	Send a processed vertical piece of the original pixmap. The destination is between xLeft and xLeft+pixmap.width().

Public Member Functions
