read_fft_optimization_dataread_fft_optimization_dataReadFftOptimizationDataread_fft_optimization_dataReadFftOptimizationDataReadFftOptimizationData loads data for optimizing the
runtime of the FFT from the file given by FileNameFileNameFileNameFileNameFileNamefileName. The
optimization data must have been determined previously with
optimize_fft_speedoptimize_fft_speedOptimizeFftSpeedoptimize_fft_speedOptimizeFftSpeedOptimizeFftSpeed and must have been stored with
write_fft_optimization_datawrite_fft_optimization_dataWriteFftOptimizationDatawrite_fft_optimization_dataWriteFftOptimizationDataWriteFftOptimizationData. If the stored data have been
determined for the image sizes to be used in the application, a call
to optimize_fft_speedoptimize_fft_speedOptimizeFftSpeedoptimize_fft_speedOptimizeFftSpeedOptimizeFftSpeed is unnecessary. It should be noted
that the data should only be used on the same machine on which they
were determined with optimize_fft_speedoptimize_fft_speedOptimizeFftSpeedoptimize_fft_speedOptimizeFftSpeedOptimizeFftSpeed. If this is not
observed the runtimes will not be optimal. Furthermore, it should
be noted that optimization data that were created with Standard
HALCON cannot be used with Parallel HALCON and vice versa.

- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.
File name of the optimization data.
Default value:
