module Vips
attach_function :vips_interpolate_new, [:string], :pointer
# An interpolator. One of these can be given to operations like
# {Image#affine} or {Image#mapim} to select the type of pixel interpolation
# to use.
#
# To see all interpolators supported by your
# libvips, try
#
# ```
# $ vips -l interpolate
# ```
#
# But at least these should be available:
#
# * `:nearest` Nearest-neighbour interpolation.
# * `:bilinear` Bilinear interpolation.
# * `:bicubic` Bicubic interpolation.
# * `:lbb` Reduced halo bicubic interpolation.
# * `:nohalo` Edge sharpening resampler with halo reduction.
# * `:vsqbs` B-Splines with antialiasing smoothing.
#
# For example:
#
# ```ruby
# im = im.affine [2, 0, 0, 2],
# :interpolate => Vips::Interpolate.new(:bicubic)
# ```
class Interpolate < Vips::Object
# the layout of the VipsInterpolate struct
module InterpolateLayout
def self.included base
base.class_eval do
layout :parent, Vips::Object::Struct
# rest opaque
end
end
end
class Struct < Vips::Object::Struct
include InterpolateLayout
end
class ManagedStruct < Vips::Object::ManagedStruct
include InterpolateLayout
end

ptr = Vips::vips_interpolate_new name
