Enumeration Type Documentation

enum OIIO_AGGREGATE

OIIO_AGGREGATE describes whether our TypeDesc is a simple scalar of one of the OIIO_BASETYPE's, or one of several simple OIIO_AGGREGATEs.

Note that OIIO_AGGREGATEs and arrays are different. A TypeDesc(FLOAT,3) is an array of three floats, a TypeDesc(FLOAT,VEC3) is a single 3-component vector comprised of floats, and TypeDesc(FLOAT,3,VEC3) is an array of 3 vectors, each of which is comprised of 3 floats.

Enumerator
OIIO_AGGREGATE_SCALAR	A single scalar value (such as a raw `int` or `float` in C). This is the default.
OIIO_AGGREGATE_VEC2	2 values representing a 2D vector.
OIIO_AGGREGATE_VEC3	3 values representing a 3D vector.
OIIO_AGGREGATE_VEC4	4 values representing a 4D vector.
OIIO_AGGREGATE_MATRIX33	9 values representing a 3x3 matrix.
OIIO_AGGREGATE_MATRIX44	16 values representing a 4x4 matrix.

enum OIIO_BASETYPE

OIIO_BASETYPE is a simple enum describing the base data types that correspond (mostly) to the C/C++ built-in types.

Enumerator

OIIO_BASETYPE_UCHAR
OIIO_BASETYPE_INT8	8-bit int values ranging from -128..127, (C/C++ `char`).
OIIO_BASETYPE_CHAR
OIIO_BASETYPE_UINT16	16-bit int values ranging from 0..65535, (C/C++ `unsigned short`).
OIIO_BASETYPE_USHORT
OIIO_BASETYPE_INT16	16-bit int values ranging from -32768..32767, (C/C++ `short`).
OIIO_BASETYPE_SHORT
OIIO_BASETYPE_UINT32	32-bit unsigned int values (C/C++ `unsigned int`).
OIIO_BASETYPE_UINT
OIIO_BASETYPE_INT32	signed 32-bit int values (C/C++ `int`).
OIIO_BASETYPE_INT
OIIO_BASETYPE_UINT64	64-bit unsigned int values (C/C++ `unsigned long long` on most architectures).
OIIO_BASETYPE_ULONGLONG
OIIO_BASETYPE_INT64	signed 64-bit int values (C/C++ `long long` on most architectures).
OIIO_BASETYPE_LONGLONG
OIIO_BASETYPE_HALF	16-bit IEEE floating point values (OpenEXR `half`).
OIIO_BASETYPE_FLOAT	32-bit IEEE floating point values, (C/C++ `float`).
OIIO_BASETYPE_DOUBLE	64-bit IEEE floating point values, (C/C++ `double`).

enum OIIO_VECSEMANTICS

OIIO_VECSEMANTICS gives hints about what the data represent (for example, if a spatial vector quantity should transform as a point, direction vector, or surface normal).

Enumerator
OIIO_VECSEMANTICS_NOXFORM	No semantic hints.
OIIO_VECSEMANTICS_NOSEMANTICS	No semantic hints.
OIIO_VECSEMANTICS_COLOR	Color.
OIIO_VECSEMANTICS_POINT	Point: a spatial location.
OIIO_VECSEMANTICS_VECTOR	Vector: a spatial direction.
OIIO_VECSEMANTICS_NORMAL	Normal: a surface normal.
OIIO_VECSEMANTICS_TIMECODE	indicates an `int[2]` representing the standard 4-byte encoding of an SMPTE timecode.
OIIO_VECSEMANTICS_KEYCODE	indicates an `int[7]` representing the standard 28-byte encoding of an SMPTE keycode.
OIIO_VECSEMANTICS_RATIONAL	A VEC2 representing a rational number `val[0] / val[1]`

Function Documentation

OIIOC_API OIIO_TypeDesc OIIO_TypeDesc_from_string ( const char * typestring )

Construct from a string (e.g., "float[3]"). If no valid type could be assembled, set basetype to OIIO_BASETYPE_UNKNOWN.

Examples: ``` TypeDesc_from_string("int") == OIIO_TypeInt // C++ int32_t TypeDesc_from_string("float") == OIIO_TypeFloat // C++ float TypeDesc_from_string("uint16") == OIIO_TYPEUInt16 // C++ uint16_t TypeDesc_from_string("float[4]") == FIXME: unimplemented! ```
