Method: Magick::Image#morphology

Defined in:

ext/RMagick/rmimage.cpp

#morphology(method_v, iterations, kernel_v) ⇒ Magick::Image

Apply a user supplied kernel to the image according to the given mophology method.

Parameters:

• method_v (Magick::MorphologyMethod) —

  the morphology method

• iterations (Numeric) —

  apply the operation this many times (or no change). A value of -1 means loop until no change found. How this is applied may depend on the morphology method. Typically this is a value of 1.

• kernel_v (Magick::KernelInfo) —

  morphology kernel to apply

Returns:

• (Magick::Image) —

  a new image
