Description

The operator read_variation_modelread_variation_modelReadVariationModelReadVariationModelread_variation_model reads a variation model, which has been written with write_variation_modelwrite_variation_modelWriteVariationModelWriteVariationModelwrite_variation_model, from the file FileNameFileNameFileNamefileNamefile_name. The default HALCON file extension for a variation model is 'vam'.

Execution Information

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

This operator returns a handle. Note that the state of an instance of this handle type may be changed by specific operators even though the handle is used as an input parameter by those operators.

Parameters

FileNameFileNameFileNamefileNamefile_name (input_control)  filename.read → HTuplestrHTupleHtuple (string) (string) (HString) (char*)

File name.

File extension: .vam

ModelIDModelIDModelIDmodelIDmodel_id (output_control)  variation_model → HVariationModel, HTupleHHandleHTupleHtuple (handle) (IntPtr) (HHandle) (handle)

ID of the variation model.

Result

If the file name is valid, the operator read_variation_modelread_variation_modelReadVariationModelReadVariationModelread_variation_model returns 2 ( H_MSG_TRUE) . If necessary an exception is raised.
