	Creates a new Woolz object in which the background value is as given. The given object must be either a 2D or 3D domain object with a valid domain, however it's values can be NULL. If the values are NULL then a new value table is created with the same grey type as the given background value, or if non-NULL then a new value table is created while sharing the values of the original object's value table when this is possible. The given object remains unchanged apart from linkcounts. More...

This is a generalisation of the original invert and allows for the "normal" inversion of 255-g for byte images. The user must ensure the grey-value type of the given object can hold the result e.g. if the result is negative.

Creates a new Woolz object in which the background value is as given. The given object must be either a 2D or 3D domain object with a valid domain, however it's values can be NULL.

◆ WlzGreyInvertMinMax()

WlzErrorNum WlzGreyInvertMinMax	(	WlzObject *	obj,
		WlzPixelV	min,
		WlzPixelV	max
	)

Invert the Grey values of an object within a given
range. The supplied min and max values define the grey
transformation by:

\[ g' = g_{max} + g_{min} - g \]

which means that g=gmax gives g'=gmin and g=gmin gives
g'=gmax. This is a generalisation of the original invert and allows for the "normal" inversion of 255-g for byte images. The user must ensure the grey-value type of the given object can hold the result e.g. if the result is
negative. Note it is assumed that min and max have
a grey type which can be converted to the grey-type
of the given image.

Returns: Woolz error.

Parameters

obj	Input object.
min	Minimu grey value for the inversion function.
max	Maximun value for the inversion function.

mask object. The mask object can be a 2D, 3D, polygon

error. A 2D mask with a 3D object will be applied to
each plane in turn.

Returns: New object with the same domain as the input object but with values in the intersection with the mask domain set to the mask value. NULL on error.

Calculate the pixel value for a given channel. For grey-pixel types the colour channel values are set equal to the grey value i.e. the pixel is assumed to be (g,g,g). If the grey-channel is requested of a colour pixel the modulus is returned.

◆ WlzTiledValuesMode()

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).

Returns: Flags specifying how the value table may be used.

Parameters

tv	The given tiled values.
dstErr	Destination error pointer, may be NULL.
