Functions
WlzTiledValues *	WlzMakeTiledValues (int dim, int vRank, WlzErrorNum *dstErr)
	Allocates a new tiled value table, but without allocating any indices or tiles. More...
WlzErrorNum	WlzFreeTiledValues (WlzTiledValues *tVal)
	Frees a tiled value table. More...
WlzTiledValues *	WlzNewTiledValues (WlzTiledValues *gVal, WlzPixelV bgdV, WlzErrorNum *dstErr)
	Creates a new tiled values table which shares both the grey value tiles and indexing with the given tiled values. This is done by using the original_table field. More...
WlzObject *	WlzMakeTiledValuesFromObj (WlzObject *gObj, size_t tileSz, int copyValues, WlzGreyType gType, unsigned int vRank, unsigned int *vDim, WlzPixelV bgdV, WlzErrorNum *dstErr)
	Creates a tiled object from the given object. More...
WlzErrorNum	WlzMakeTiledValuesTiles (WlzTiledValues *tVal)
	Allocates tiles without a memory mapped file for the tiles values and sets background value within the tiles. More...
int	WlzTiledValuesMode (WlzTiledValues *tv, WlzErrorNum *dstErr)
	Determines how the tiled values of a tiles value table may be used. If memory mapping is in use then the mode in which the file (containing the memory mapped values) was opened determines the modes in which the tiled values can be accessed. Inappropriate access (eg attempting to change a grey value in a memory mapped tiled values table that was opened for read only) will generate a memory fault. The returned value is a bit mask in which WLZ_IOFLAGS_READ will be set iff grey values can be read and WLZ_IOFLAGS_WRITE will be set iff the grey values can be written to (ie modified). More...
WlzTiledValueBuffer *	WlzMakeTiledValueBuffer (WlzTiledValues *tVal, WlzErrorNum *dstErr)
	Makes a new tiled values buffer for the given tiled values table. More...
void	WlzFreeTiledValueBuffer (WlzTiledValueBuffer *tBuf)
	Frees the given tiled values buffer including it's line buffer. More...
void	WlzTiledValueBufferFlush (WlzTiledValueBuffer *tvb, WlzTiledValues *tv)
	Flushes the values in the tiled values buffer to the tiled values table. More...
void	WlzTiledValueBufferFill (WlzTiledValueBuffer *tvb, WlzTiledValues *tv)
	Fills the tiled values buffer using values from the tiled values table. More...
WlzObject *	WlzMakeTiledValuesObj2D (WlzObject *gObj, size_t tileSz, int setTiles, WlzGreyType gType, unsigned int vRank, unsigned int *vDim, WlzPixelV bgdV, WlzErrorNum *dstErr)
	Creates a 2D domain object which has the same domain as the given 2D domain object but a tiled value table. More...
WlzObject *	WlzMakeTiledValuesObj3D (WlzObject *gObj, size_t tileSz, int setTiles, WlzGreyType gType, unsigned int vRank, unsigned int *vDim, WlzPixelV bgdV, WlzErrorNum *dstErr)
	Creates a 3D domain object which has the same domain as the given 3D domain object but a tiled value table. More...
void	WlzTiledValuesCopyLine (WlzTiledValues *tv, WlzGreyP gP, int pl, int ln, int kl1, int lkl)
	Copies a single line of grey values to a tiled value table. This is done within the valid tiles which may lie outside of an object's domain, so care should be used when calling this function. All the given coordinate values are with respect to the tiled value table's origin. If the tiled values have a number of values per element greater than one then the given buffer must have too. More...
int	WlzTiledValuesValPerElm (WlzTiledValues *tVal)
	Computes the number of values per pixel/voxel for a tiled value table. More...
