cairo_filter_t.Rd#cairo_filter_t is used to indicate what filtering should be applied when reading pixel values from patterns. See cairo_pattern_set_filter() for indicating the desired filter to be used with a particular pattern.
cairo_filter_t
An object of class list of length 6.
Since: 1.0
A high-performance filter, with quality similar to %CAIRO_FILTER_NEAREST (Since 1.0)
A reasonable-performance filter, with quality similar to %CAIRO_FILTER_BILINEAR (Since 1.0)
The highest-quality available, performance may not be suitable for interactive use. (Since 1.0)
Nearest-neighbor filtering (Since 1.0)
Linear interpolation in two dimensions (Since 1.0)
This filter value is currently unimplemented, and should not be used in current code. (Since 1.0)
