magickSepiaToneImage method

Future<bool> magickSepiaToneImage(
  1. double threshold
)

MagickSepiaToneImage() applies a special effect to the image, similar to the effect achieved in a photo darkroom by sepia toning. Threshold ranges from 0 to QuantumRange and is a measure of the extent of the sepia toning. A threshold of 80 is a good starting point for a reasonable tone.

This method runs inside an isolate different from the main isolate.

  • threshold: Define the extent of the sepia toning.

Implementation

Future<bool> magickSepiaToneImage(double threshold) async =>
    await _magickCompute(
      _magickSepiaToneImage,
      _MagickSepiaToneImageParams(
        _wandPtr.address,
        threshold,
      ),
    );
