    static final int
    BILINEAR
    Best quality/speed balance; use this mode by
    default.
    static final int
    HYPER
    This is the slowest and highest quality
    reconstruction function.
    static final int
    NEAREST
    Nearest neighbor sampling; this is the fastest
    and lowest quality mode.
    static final int
    TILES
    This is an accurate simulation of the PostScript
    image operator without any interpolation enabled.

    • NEAREST

      static final int NEAREST
      Nearest neighbor sampling; this is the fastest
      and lowest quality mode. Quality is normally unacceptable when scaling
      down, but may be OK when scaling up.

    • TILES

      static final int TILES
      This is an accurate simulation of the PostScript
      image operator without any interpolation enabled. Each pixel is
      rendered as a tiny parallelogram of solid color, the edges of which
      are implemented with antialiasing. It resembles nearest neighbor for
      enlargement, and bilinear for reduction.

    • BILINEAR

      static final int BILINEAR
      Best quality/speed balance; use this mode by
      default. Bilinear interpolation. For enlargement, it is
      equivalent to point-sampling the ideal bilinear-interpolated image.
      For reduction, it is equivalent to laying down small tiles and
      integrating over the coverage area.

    • HYPER

      static final int HYPER
      This is the slowest and highest quality
      reconstruction function. It is derived from the hyperbolic filters in
      Wolberg's "Digital Image Warping", and is formally defined as the
      hyperbolic-filter sampling the ideal hyperbolic-filter interpolated
      image (the filter is designed to be idempotent for 1:1 pixel mapping).
      **Deprecated**: this interpolation filter is deprecated, as in reality
      it has a lower quality than the @GDK_INTERP_BILINEAR filter
      (Since: 2.38)
