Member Function Documentation

◆ signalTransferPiece

void DlgFilterWorker::signalTransferPiece	(	int	xLeft,
		QImage	image
	)

signal

Send a processed vertical piece of the original pixmap. The destination is between xLeft and xLeft+pixmap.width()

◆ slotNewParameters

void DlgFilterWorker::slotNewParameters	(	ColorFilterMode	colorFilterMode,
		double	low,
		double	high
	)

slot

Start processing with a new set of parameters. Any ongoing processing is interrupted when m_filterMode changes.
