| FwStatus | fwiDCTQuantFwd8x8_JPEG_16s_C1 | ( | const Fw16s * pSrc, Fw16s * pDst, const Fw16u * pQuantFwdTable ); | |
| FwStatus | fwiDCTQuantFwd8x8_JPEG_16s_C1I | ( | Fw16s * pDst, const Fw16u * pQuantFwdTable ); |
| pDst | Pointer to a location in a destination buffer. | |
| pQuantFwdTable | Pointer to the forward quantization table (encoder). | |
| pSrc | Pointer to a location in a source buffer. |
These functions read an 8X8 data block of 16-bit signed data in a source buffer, perform forward DCT and quantization, then write the output data block. The data block can be written to a destination buffer or to the same location.
