Description

tuple_constanttuple_constantTupleConstantTupleConstanttuple_constant generates a new tuple with the value of a HDevelop language constant.

Attention

H_INT64_MIN and H_INT64_MAX will both produce an error if 32-bit HALCON is being used, as they cannot be represented in the then 32-bit integer used in tuples.

H_INT_MIN and H_INT_MAX will produce different values depending on whether HALCON 32- or 64-bit is being used.

Execution Information

  • Multithreading type: independent (runs in parallel even with exclusive operators).
  • Multithreading scope: global (may be called from any thread).
  • Processed without parallelization.

Parameters
