Functions

WlzObjectWlzRGBAMultiThreshold (WlzObject *obj, WlzPixelV lowVal, WlzPixelV highVal, WlzUInt combineMode, WlzErrorNum *dstErr)
 Apply independent thresholds to each colour channel independently and combine according to the settings encoded in combineMode. Each channel can have one of two modes: WLZ_BO_AND and WLZ_BO_OR. These are encoded into a single mode variable using the RGBA macro, e.g.: WLZ_RGBA_RGBA_SET(combineMode, redMode, greenMode, blueMode, 255);.
