1980
|
|
|
1981 The "best" way to do this is to sort the colors by diversity and place
|
|
|
1982 the most diverse colors into the limited palette. Unfortunately this
|
|
|
1983 results in widely varying colors being displayed in the interval during
|
|
|
1984 which the windows palette has been set, and the mapping of the shadow
|
|
|
1985 surface to the new palette. This is especially noticeable during fades.
|
|
|
1986
|
|
|
1987 To deal with this problem, we can copy a predetermined portion of the
|
|
|
1988 full palette, and use that as the limited palette. This allows colors
|
|
|
1989 to fade smoothly as the remapping is very similar on each palette change.
|
|
|
1990 Unfortunately, this breaks applications which partition the palette into
|
|
|
1991 distinct and widely varying areas, expecting all colors to be available.
|
|
|
1992
|
|
|
1993 I'm making them both available, chosen at compile time.
|

|
1994 If you want the chunk-o-palette algorithm, define SIMPLE_COMPRESSION,

1995 otherwise the sort-by-diversity algorithm will be used.
