| pDst | Pointer to a location in a destination buffer. | |
| pSrc | Pointer to a location in a source buffer. | |
| pSrcDst | Pointer to a location in a buffer that contains both the source and destination. |
These functions compute the forward and inverse DCT coefficients of an 8X8 block of image data.
Results can be written to a destination buffer or back to the source buffer.
