Functions
WlzCompoundArray *	WlzRGBAToCompound (WlzObject *obj, WlzRGBAColorSpace colSpc, WlzErrorNum *dstErr)
	Convert a RGBA image to a compound object. The RGBA channels are at array indices 0,1,2,3 respectively and the sub-object grey types will be WLZ_GREY_UBYTE. More...
WlzObject *	WlzCompoundToRGBA (WlzCompoundArray *cmpnd, WlzRGBAColorSpace colSpc, WlzErrorNum *dstErr)
	Creates a WLZ_GREY_RGBA valued object from the given compound array. This is a static function which will always be called with valid parameters so they aren't checked. If all members of the compound array are empty then the returned object will be empty too. More...
WlzObject *	WlzRGBAToModulus (WlzObject *obj, WlzErrorNum *dstErr)
	Calculate the modulus of the rgb values and return in an image of grey type WLZ_GREY_SHORT. More...
WlzObject *	WlzIndexToRGBA (WlzObject *obj, unsigned char colormap[3][256], WlzErrorNum *dstErr)
	Convert a grey-level woolz object to RGBA via a colourmap look-up table. Values are clamped to [0,255] and the LUT is assumed to be unsigned byte 3x256. More...
WlzObject *	WlzRGBAToChannel (WlzObject *obj, WlzRGBAColorChannel chan, WlzErrorNum *dstErr)
