Constructor Detail

NppiJpegFrameDescr

public NppiJpegFrameDescr()

Default native constructor.

NppiJpegFrameDescr

public NppiJpegFrameDescr(long size)

Native array allocator. Access with Pointer.position(long).

NppiJpegFrameDescr

public NppiJpegFrameDescr(Pointer p)

Pointer cast constructor. Invokes Pointer.Pointer(Pointer).

Method Detail

position

public NppiJpegFrameDescr position(long position)

Overrides:

position in class Pointer

nComponents

@Cast(value="Npp8u")
public byte nComponents()

Number of components in frame

nComponents

public NppiJpegFrameDescr nComponents(byte setter)

oSizeInBlocks

@ByRef
public NppiSize oSizeInBlocks()

Size of component with 1x1 subsampling (usually luma) in DCT blocks.

oSizeInBlocks

public NppiJpegFrameDescr oSizeInBlocks(NppiSize setter)

aComponentSubsampling

@ByRef
public NppiSize aComponentSubsampling(int i)

Subsampling factors of component, as described in frame header

aComponentSubsampling

public NppiJpegFrameDescr aComponentSubsampling(int i,
                                                NppiSize setter)

aComponentSubsampling

@MemberGetter
public NppiSize aComponentSubsampling()

apComponentBuffer

@Cast(value="Npp16s*")
public ShortPointer apComponentBuffer(int i)

Buffer containing DCT coefficients. Use \ref nppiJpegDecodeGetDCTBufferSize to determine size of this buffer. After decoding, coefficients will be stored in zig-zag order, block by block. So the c-th coeffient of block (x, y) will be stored at buffer[64 * (y * interleavedComponentWidthInBlocks + x) + c].

apComponentBuffer

public NppiJpegFrameDescr apComponentBuffer(int i,
                                            ShortPointer setter)

apComponentBuffer

@MemberGetter
 @Cast(value="Npp16s**")
public PointerPointer apComponentBuffer()
