Method: Magick::Image#adaptive_sharpen_channel

Defined in:
ext/RMagick/rmimage.cpp

#adaptive_sharpen_channel(radius = 0.0, sigma = 1.0, channel = Magick::AllChannels) ⇒ Magick::Image #adaptive_sharpen_channel(radius = 0.0, sigma = 1.0, *channels) ⇒ Magick::Image

The same as #adaptive_sharpen except only the specified channels are sharpened.

Overloads:

  • #adaptive_sharpen_channel(radius = 0.0, sigma = 1.0, channel = Magick::AllChannels) ⇒ Magick::Image

    Parameters:

    • radius (Numeric) (defaults to: 0.0) —

      The radius of the Gaussian in pixels, not counting the center pixel.

    • sigma (Numeric) (defaults to: 1.0) —

      The standard deviation of the Laplacian, in pixels.

    • channel (Magick::ChannelType) (defaults to: Magick::AllChannels) —

      a ChannelType arguments.

  • #adaptive_sharpen_channel(radius = 0.0, sigma = 1.0, *channels) ⇒ Magick::Image

    Parameters:

    • radius (Numeric) (defaults to: 0.0) —

      The radius of the Gaussian in pixels, not counting the center pixel.

    • sigma (Numeric) (defaults to: 1.0) —

      The standard deviation of the Laplacian, in pixels.

    • *channels (Magick::ChannelType) —

      one or more ChannelType arguments.
