This is only a special notation to make clear that these parameters are changedby the macros. So do not pass pointers to variables but the variables itself to the macro.Note, that the ÀÔÖ arrays ÊÓÛ and ÓÐ are allocated with a fixed size on the stack usingÅ Ç ÈÊ ÈÊ. This define equals the maximum allowed number of objects per input objectparameter of a HALCON operator. Keep in mind that this number is quite large (100 000 in thecurrent version). Thus, it might be better to allocate the arrays dynamically using ÀÐÐÓÌÑÔ(see section 3.2.1) with only as much elements as needed (see ÀÊ맧ºµ on page 61).6.1.2 ÀÐÐËÑÀÐÐËÑ (see Fig. 6.1) extends ÀÐÐÊ: Not only the region but also all gray value chan-HALCON 6.0
