Constructor & Destructor Documentation

DD::Image::DirectGeneralTile::DirectGeneralTile	(	Iop &	input,
		const ChannelSet &	chans,
		bool	mt = false,
		InterestRatchet *	ir = NULL
	)		[inline]

load the entire requested area of /input/, for /channels/; if /mt/ is true then it may spawn threads to render the area in parallel. the InterestRatchet /ir/ might be passed down to the underlying RowCacheTile, if it uses one.

DD::Image::DirectGeneralTile::DirectGeneralTile	(	Iop &	input,
		const Box &	box,
		const ChannelSet &	chans,
		bool	mt = false,
		InterestRatchet *	ir = NULL
	)		[inline]

load the area /box/ on /input/, for /channels/; if /mt/ is true then it may spawn threads to render the area in parallel. the InterestRatchet /ir/ might be passed down to the underlying RowCacheTile, if it uses one.

DD::Image::DirectGeneralTile::DirectGeneralTile	(	Iop &	input,
		int	x,
		int	y,
		int	r,
		int	t,
		const ChannelSet &	chans,
		bool	mt = false,
		InterestRatchet *	ir = NULL
	)		[inline]

load the area (x, y, r, t) on /input/, for /channels/; if /mt/ is true then it may spawn threads to render the area in parallel. the InterestRatchet /ir/ might be passed down to the underlying RowCacheTile, if it uses one.
