apComponentBuffer

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].

Declaration

public CUdeviceptr[] apComponentBuffer

Field Value

Type	Description
CUdeviceptr[]
