Methods:

• public void @2d (Scaler vscale, Format format, void* src, int src_stride, void* dest, int dest_stride, uint x, uint y, uint width, uint height)
  Scale a rectangle of pixels in src with src_stride to dest with dest_stride using the horizontal scaler hscaler and the vertical scaler vscale.
• public void free ()
  Free a previously allocated Scaler this.
• public double get_coeff (uint out_offset, out uint in_offset, out uint n_taps)
  For a given pixel at out_offset, get the first required input pixel at in_offset and the return.length filter coefficients.
• public uint get_max_taps ()
  Get the maximum number of taps for this .
• public void horizontal (Format format, void* src, void* dest, uint dest_offset, uint width)
  Horizontally scale the pixels in src to dest , starting from dest_offset for width samples.
• public void vertical (Format format, void* src_lines, void* dest, uint dest_offset, uint width)
  Vertically combine width pixels in the lines in src_lines to dest.
