public class Type extends BaseObj
A Type describes the Element
and dimensions used for an Allocation
or a parallel operation. Types are created through Type.Builder
.
A Type always includes an Element
and an X
dimension. A Type may be multidimensional, up to three dimensions. A nonzero
value in the Y or Z dimensions indicates that the dimension is present. Note
that a Type with only a given X dimension and a Type with the same X
dimension but Y = 1 are not equivalent.
A Type also supports inclusion of level of detail (LOD) or cube map faces. LOD and cube map faces are booleans to indicate present or not present.
A Type also supports YUV format information to support an
Allocation
in a YUV format. The YUV formats
supported are ImageFormat.YV12
,
ImageFormat.NV21
, and
ImageFormat.YUV_420_888
