Sheldon is clipping the black and white ranges.
|
||
|
|
||
|
The usual reason for doing this is for dirty images (caused by poor digitizing or
|
||
|
sampling or re-sampling color depth loss due to scaling). By using a clipping threshold
|
||
|
at either end of the rgb range, blacks that are not quite black don't match to some other
|
||
|
dark color and whites that are not quite white don't match to some other light color.
|
||
|
|
||
|
I too put this in place as a clipping option when I wrote Bmp2SHR about a year ago in my
|
||
|
Brooks output routines but it worked a little differently. I didn't build it into a
|
||
|
palette for one thing.
|
||
|
|
||
|
Sheldon's weighting favours clipping blue gun values at both ends of the range.
|
||
|
|
||
|
Red is clipped more than green in the high range, and green is clipped more than
|
||
|
red in the low range.
