Description

deserialize_hom_mat2ddeserialize_hom_mat2dDeserializeHomMat2dDeserializeHomMat2ddeserialize_hom_mat2d deserializes a homogeneous 2D transformation matrix, that was serialized by serialize_hom_mat2dserialize_hom_mat2dSerializeHomMat2dSerializeHomMat2dserialize_hom_mat2d (see fwrite_serialized_itemfwrite_serialized_itemFwriteSerializedItemFwriteSerializedItemfwrite_serialized_item for an introduction of the basic principle of serialization). The serialized transformation matrix is defined by the handle SerializedItemHandleSerializedItemHandleSerializedItemHandleserializedItemHandleserialized_item_handle. The deserialized values are stored in an automatically created transformation matrix with the handle HomMat2DHomMat2DHomMat2DhomMat2Dhom_mat_2d.

Execution Information

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

Parameters

SerializedItemHandleSerializedItemHandleSerializedItemHandleserializedItemHandleserialized_item_handle (input_control)  serialized_item → HSerializedItem, HTupleHHandleHTupleHtuple (handle) (IntPtr) (HHandle) (handle)

Handle of the serialized item.

Transformation matrix.

Result

If the parameters are valid, the operator deserialize_hom_mat2ddeserialize_hom_mat2dDeserializeHomMat2dDeserializeHomMat2ddeserialize_hom_mat2d returns the value 2 ( H_MSG_TRUE) . If necessary, an exception is raised.
