magickSharpenImage method

Future<bool> magickSharpenImage({
  1. required double radius,
  2. required double sigma,
})

MagickSharpenImage() sharpens an image. We convolve the image with a Gaussian operator of the given radius and standard deviation (sigma). For reasonable results, the radius should be larger than sigma. Use a radius of 0 and MagickSharpenImage() selects a suitable radius for you.

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

  • radius: the radius of the Gaussian, in pixels, not counting the center pixel.
  • sigma: the standard deviation of the Gaussian, in pixels.

Implementation

Future<bool> magickSharpenImage({
  required double radius,
  required double sigma,
}) async =>
    await _magickCompute(
      _magickSharpenImage,
      _MagickSharpenImageParams(
        _wandPtr.address,
        radius,
        sigma,
      ),
    );
