magickGetSamplingFactors method

Float64List? magickGetSamplingFactors()

Gets the horizontal and vertical sampling factor.

Implementation

Float64List? magickGetSamplingFactors() => using((Arena arena) {
      final Pointer<Size> numFactorsPtr = arena();
      final Pointer<Double> factorsPtr =
          _magickWandBindings.MagickGetSamplingFactors(
              _wandPtr, numFactorsPtr);
      final int numFactors = numFactorsPtr.value;
      final Float64List? factors = factorsPtr.toFloat64List(numFactors);
      _magickRelinquishMemory(factorsPtr.cast());
      return factors;
    });
