create :: IO Texture

Deprecated: as of CUDA version 3.2

Create a new texture reference. Once created, the application must call setPtr to associate the reference with allocated memory. Other texture reference functions are used to specify the format and interpretation to be used when the memory is read through this reference.

destroy :: Texture -> IO ()

Deprecated: as of CUDA version 3.2

Destroy a texture reference

bind :: Texture -> DevicePtr a -> Int64 -> IO ()

Bind a linear array address of the given size (bytes) as a texture reference. Any previously bound references are unbound.

bind2D :: Texture -> Format -> Int -> DevicePtr a -> (Int, Int) -> Int64 -> IO ()

Bind a linear address range to the given texture reference as a two-dimensional arena. Any previously bound reference is unbound. Note that calls to setFormat can not follow a call to bind2D for the same texture reference.

getAddressMode :: Texture -> Int -> IO AddressMode

Get the addressing mode used by a texture reference, corresponding to the given dimension (currently the only supported dimension values are 0 or 1).

getFilterMode :: Texture -> IO FilterMode

Get the filtering mode used by a texture reference

getFormat :: Texture -> IO (Format, Int)

Get the data format and number of channel components of the bound texture

setAddressMode :: Texture -> Int -> AddressMode -> IO ()

Specify the addressing mode for the given dimension of a texture reference

setFilterMode :: Texture -> FilterMode -> IO ()

Specify the filtering mode to be used when reading memory through a texture reference

setFormat :: Texture -> Format -> Int -> IO ()

Specify the format of the data and number of packed components per element to be read by the texture reference

setReadMode :: Texture -> ReadMode -> IO ()

Specify additional characteristics for reading and indexing the texture reference
