| FwStatus | fwiDCTQuantInv8x8_JPEG_16s_C1 | ( | const Fw16s * pSrc, Fw16s * pDst, const Fw16u * pQuantInvTable ); | |
| FwStatus | fwiDCTQuantInv8x8_JPEG_16s_C1I | ( | Fw16s * pDst, const Fw16u * pQuantInvTable ); |
| pDst | Pointer to a location in a destination buffer. | |
| pQuantInvTable | Pointer to the inverse quantization table (decoder). | |
| pSrc | Pointer to a location in a source buffer. |
These functions read a block of uncompressed image data in a source buffer, perform dequantization and inverse DCT, then write an 8X8 data block. The data block can be written to a destination buffer or to the same location.
