The abstract base class for the various VIPS interpolation functions.
172
Use "vips --list classes" to see all the interpolators available.
173
</p>
174
<p>
175
An interpolator consists of a function to perform the interpolation, plus
176
some extra data fields which tell vips how to call the function and what
177
data it needs.
178
</p>
179
<p>
180
<em class="parameter"><code>window_size</code></em> is the size of the window that the interpolator needs. For
181
example, a bicubic interpolator needs to see a window of 4x4 pixels to be
182
able to interpolate a value.
183
</p>
184
<p>
185
You can either have a function in <em class="parameter"><code>get_window_size</code></em> which returns the window
186
that a specific interpolator needs, or you can leave <em class="parameter"><code>get_window_size</code></em> <code class="literal">NULL</code>
187
and set a constant value in <em class="parameter"><code>window_size</code></em>.
188
</p>
189
<p>
190
<em class="parameter"><code>window_offset</code></em> is how much to offset the window up and left of (x, y). For
191
example, a bicubic interpolator will want a <em class="parameter"><code>window_offset</code></em> of 1.
192
</p>
193
<p>
194
You can either have a function in <em class="parameter"><code>get_window_offset</code></em> which returns the
195
offset that a specific interpolator needs, or you can leave
196
<em class="parameter"><code>get_window_offset</code></em> <code class="literal">NULL</code> and set a constant value in <em class="parameter"><code>window_offset</code></em>.
197
</p>
198
<p>
199
You also need to set <em class="parameter"><code>nickname</code></em> and <em class="parameter"><code>description</code></em> in <a class="link" href="libvips-VipsArgument.html#VipsObject"><span class="type">VipsObject</span></a>.
