* These processes all use a common table prepared by the routine below.
|

*
|
||||
* For most steps we can mathematically guarantee that the initial value
|
||||
* of x is within MAXJSAMPLE+1 of the legal range, so a table running from
|
||||
* -(MAXJSAMPLE+1) to 2*MAXJSAMPLE+1 is sufficient. But for the initial
|
||||
* limiting step (just after the IDCT), a wildly out-of-range value is
|
||||
* possible if the input data is corrupt. To avoid any chance of indexing
|
||||
* of x is within 2*(MAXJSAMPLE+1) of the legal range, so a table running
|
||||
* from -2*(MAXJSAMPLE+1) to 3*MAXJSAMPLE+2 is sufficient. But for the
|
||||
* initial limiting step (just after the IDCT), a wildly out-of-range value
|
||||
* is possible if the input data is corrupt. To avoid any chance of indexing
|
||||
* off the end of memory and getting a bad-pointer trap, we perform the
|
||||
* post-IDCT limiting thus:
|
||||
* x = range_limit[x & MASK];
|
||||
* x = (sample_range_limit - SUBSET)[(x + CENTER) & MASK];
|
||||
* where MASK is 2 bits wider than legal sample data, ie 10 bits for 8-bit
|
||||
* samples. Under normal circumstances this is more than enough range and
|
||||
* a correct output will be generated; with bogus input data the mask will
|
||||
* cause wraparound, and we will safely generate a bogus-but-in-range output.
|
||||
* For the post-IDCT step, we want to convert the data from signed to unsigned
|
||||
* representation by adding CENTERJSAMPLE at the same time that we limit it.
|
||||
* So the post-IDCT limiting table ends up looking like this:
|
||||
* CENTERJSAMPLE,CENTERJSAMPLE+1,...,MAXJSAMPLE,
|
||||
* MAXJSAMPLE (repeat 2*(MAXJSAMPLE+1)-CENTERJSAMPLE times),
|
||||
* 0 (repeat 2*(MAXJSAMPLE+1)-CENTERJSAMPLE times),
|
||||
* 0,1,...,CENTERJSAMPLE-1
|
||||
* Negative inputs select values from the upper half of the table after
|
||||
* masking.
|
||||
*
|
||||
* We can save some space by overlapping the start of the post-IDCT table
|
||||
* with the simpler range limiting table. The post-IDCT table begins at
|
||||
* sample_range_limit + CENTERJSAMPLE.
|
||||
* This is accomplished with SUBSET = CENTER - CENTERJSAMPLE.
|
||||
*
|
||||
* Note that the table is allocated in near data space on PCs; it's small

||||
* enough and used often enough to justify this.
