[struct]

struct { ... } SwsReadWriteOp::filter

Filter kernel to apply to each plane while sampling.

Currently, only one shared filter kernel is supported for all planes. (Optional)

Note: As with SWS_OP_FILTER_*, if a filter kernel is in use, the read operation will always output floating point values.
