+ .. gobj:prop:: fast:boolean
+
+ Use a fast version of the algorithm described in [#]_. The only
+ difference in the result from the classical algorithm is that there is
+ no Gaussian profile used and from the nature of the fast algorithm,
+ floating point precision errors might occur for large images.
+
.. gobj:prop:: addressing-mode:enum
Addressing mode specifies the behavior for pixels falling outside the
original image. See OpenCL ``sampler_t`` documentation for more information.
