Classes
class	StreamMetadata
	Container for metadata describing how to unserialize grids from and/or serialize grids to a stream (which file format, compression scheme, etc. to use) More...
struct	MultiPass
	Leaf nodes that require multi-pass I/O must inherit from this struct. More...

Namespaces

OPENVDB_API uint32_t	getDataCompression (std::ios_base &)
	Return a bitwise OR of compression option flags (COMPRESS_ZIP, COMPRESS_ACTIVE_MASK, etc.) specifying whether and how input data is compressed or output data should be compressed. More...
OPENVDB_API void	setDataCompression (std::ios_base &, uint32_t compressionFlags)

OPENVDB_API bool	getWriteGridStatsMetadata (std::ios_base &)
	Return true if grid statistics (active voxel count and bounding box, etc.) should be computed and stored as grid metadata when writing to the given stream. More...
OPENVDB_API void	setWriteGridStatsMetadata (std::ios_base &, bool writeGridStats)
	Specify whether to compute grid statistics (active voxel count and bounding box, etc.) and store them as grid metadata when writing to the given stream. More...
OPENVDB_API SharedPtr< StreamMetadata >	getStreamMetadataPtr (std::ios_base &)
	Return a shared pointer to an object that stores metadata (file format, compression scheme, etc.) for use when reading from or writing to the given stream. More...
OPENVDB_API void	setStreamMetadataPtr (std::ios_base &, SharedPtr< StreamMetadata > &, bool transfer=true)

OPENVDB_API SharedPtr< StreamMetadata >	clearStreamMetadataPtr (std::ios_base &)
	Dissociate the given stream from its metadata object (if it has one) and return a shared pointer to the object. More...
