Lars its just poor written text in the manual ignore the mix of numbers and text, use one or the other as you would with any ordinary object...
it should be ObjectGeography( xxx , 1 ) = returns the OBJ_GEO_MINX ObjectGeography( xxx , 2 ) = returns the OBJ_GEO_MINY etc etc using obj_geo_minX( a number) is a mistake in your example >>>> ObjectGeography(xxx(1) , OBJ_GEO_MIN) throws a compile time error ... <<< the error is due to the fact that it should be ObjectGeography(xxx(1) , OBJ_GEO_MINX) (or OBJ_GEO_MINY) or you havent included tehMapbasic.def file ?? teh minx will return teh lowest value easting of any of the points, the min y retirns teh lowest value northing of any of the points...THEY dont have to be from teh same point.. regards r -----Original Message----- From: Lars V. Nielsen (GisPro) [mailto:[EMAIL PROTECTED] Sent: 12 March 2004 16:00 To: MAPINFO-L Mailinglist Subject: MI-L ObjectGeography on MultiPoint / Collection objects ? For the first time I've had to consider the "new" object types, MultiPoint and Collection. When reading the reference (v6.5), I'm puzzled by content of this (too hastily?) added section : -- quote begins -- The ObjectGeography() function has been extended to support Multipoints and Collections. Both types support attributes 1 - 4 (coordinates of object's minimum bounding rectangle (MBR). OBJ_GEO_MINX (1) minimum x coordinate of an object's MBR. OBJ_GEO_MINY (2) minimum y coordinate of object's MBR. OBJ_GEO_MAXX (3) maximum x coordinate of object's MBR. OBJ GEO_MAXY (4) maximum y coordinate of object's MBR -- quote ends -- How is this to be interpreted ? There's no working sample so it's rather unclear to me what it means. Can anyone enlighten me ? My experience sofar: ObjectGeography(xxx , OBJ_GEO_MIN(1)) throws a compile time error .... ObjectGeography(xxx(1) , OBJ_GEO_MIN) throws a compile time error .... ObjectGeography(xxx , OBJ_GEO_MIN1) throws a run time error .... Best regards/Med venlig hilsen Lars V.
