| - * for 8-bit samples, INT32 for 12-bit samples.  (NOTE: Floating-point DCT
 | 
| - * implementations use an array of type FAST_FLOAT, instead.)
 | 
| - * The DCT inputs are expected to be signed (range +-CENTERJSAMPLE).
 | 
| - * The DCT outputs are returned scaled up by a factor of 8; they therefore
 | 
| - * have a range of +-8K for 8-bit data, +-128K for 12-bit data.  This
 | 
| - * convention improves accuracy in integer implementations and saves some
 | 
| - * work in floating-point ones.
 | 
| - * Quantization of the output coefficients is done by jcdctmgr.c.
