| FwStatus | fwiDCT8x8Inv_AANTransposed_16s_C1R | ( | const Fw16s * pSrc, Fw16s * pDst, Fw32s dstStep, Fw32s count ); | |
| FwStatus | fwiDCT8x8Inv_AANTransposed_16s8u_C1R | ( | const Fw16s * pSrc, Fw8u * pDst, Fw32s dstStep, Fw32s count ); |
| count | Number of the last non-zero coefficient in zig-zag order. When a block contains no non-zero coefficients, the value is -1. | |
| dstStep | Step of the destination array. | |
| pDst | Pointer to a location in a destination buffer, a location in a destination array or to a destination result. | |
| pSrc | Pointer to a block of DCT coefficients. |
These functions step through a transposed 8X8 block of DCT coefficients in a source buffer, perform an IDCT based on the AAN algorithm, and write the result to a destination buffer.
