    Cairo::Filter is used to indicate what filtering should be 

    applied when reading pixel values from patterns. 

    See Cairo::Pattern>>filter: for indicating the desired 

    filter to be used with a particular pattern.

    Members

    CAIRO_FILTER_FAST   A high-performance filter, with quality 

                        similar to CAIRO_FILTER_NEAREST (Since 1.0)

    CAIRO_FILTER_GOOD   A reasonable-performance filter, with quality 

                        similar to CAIRO_FILTER_BILINEAR (Since 1.0)

    CAIRO_FILTER_BEST   The highest-quality available, performance may not 

                        be suitable for interactive use. (Since 1.0)

    CAIRO_FILTER_NEAREST Nearest-neighbor filtering (Since 1.0)

    CAIRO_FILTER_BILINEAR Linear interpolation in two dimensions 

                        (Since 1.0)

    CAIRO_FILTER_GAUSSIAN This filter value is currently unimplemented, and 

                        should not be used in current code. (Since 1.0)

    Since 1.0
