Types
rs_allocation : Handle to an allocation

An enum with the following values: Added in API level 14
| RS_ALLOCATION_CUBEMAP_FACE_POSITIVE_X = 0 | |
|---|---|
| RS_ALLOCATION_CUBEMAP_FACE_NEGATIVE_X = 1 | |
| RS_ALLOCATION_CUBEMAP_FACE_POSITIVE_Y = 2 | |
| RS_ALLOCATION_CUBEMAP_FACE_NEGATIVE_Y = 3 | |
| RS_ALLOCATION_CUBEMAP_FACE_POSITIVE_Z = 4 | |
| RS_ALLOCATION_CUBEMAP_FACE_NEGATIVE_Z = 5 |
An enum used to specify one the six faces of a cubemap.
rs_allocation_usage_type : Bitfield to specify how an allocation is used
An enum with the following values: Added in API level 14
| RS_ALLOCATION_USAGE_SCRIPT = 0x0001 | Allocation is bound to and accessed by scripts. |
|---|---|
| RS_ALLOCATION_USAGE_GRAPHICS_TEXTURE = 0x0002 | Allocation is used as a texture source. |
| RS_ALLOCATION_USAGE_GRAPHICS_VERTEX = 0x0004 | Deprecated. |
| RS_ALLOCATION_USAGE_GRAPHICS_CONSTANTS = 0x0008 | Deprecated. |
| RS_ALLOCATION_USAGE_GRAPHICS_RENDER_TARGET = 0x0010 | Deprecated. |
| RS_ALLOCATION_USAGE_IO_INPUT = 0x0020 | Allocation is used as a Surface consumer. |
| RS_ALLOCATION_USAGE_IO_OUTPUT = 0x0040 | Allocation is used as a Surface producer. |
| RS_ALLOCATION_USAGE_SHARED = 0x0080 | Allocation's backing store is shared with another object (usually a Bitmap). Copying to or from the original source Bitmap will cause a synchronization rather than a full copy. |
These values are ORed together to specify which usages or memory spaces are relevant to an allocation or an operation on an allocation.
rs_data_kind : Element data kind
An enum with the following values: Added in API level 16
| RS_KIND_USER = 0 | No special interpretation. |
|---|---|
| RS_KIND_PIXEL_L = 7 | Luminance. |
| RS_KIND_PIXEL_A = 8 | Alpha. |
| RS_KIND_PIXEL_LA = 9 | Luminance and Alpha. |
| RS_KIND_PIXEL_RGB = 10 | Red, Green, Blue. |
| RS_KIND_PIXEL_RGBA = 11 | Red, Green, Blue, and Alpha. |
| RS_KIND_PIXEL_DEPTH = 12 | Depth for a depth texture. |
| RS_KIND_PIXEL_YUV = 13 | Luminance and chrominance. |
| RS_KIND_INVALID = 100 |
This enumeration is primarly useful for graphical data. It provides additional information to help interpret the rs_data_type.
RS_KIND_USER indicates no special interpretation is expected.
The RS_KIND_PIXEL_* values are used in conjunction with the standard data types for representing texture formats.
See the Element.createPixel() method.

rs_data_type is used to encode the type information of a basic element.
RS_TYPE_UNSIGNED_5_6_5, RS_TYPE_UNSIGNED_5_5_5_1, RS_TYPE_UNSIGNED_4_4_4_4 are for packed graphical data formats and represent vectors with per vector member sizes which are treated as a single unit for packing and alignment purposes.
