2150 |
|
2151 The "best" way to do this is to sort the colors by diversity and place |
|
2152 the most diverse colors into the limited palette. Unfortunately this |
|
2153 results in widely varying colors being displayed in the interval during |
|
2154 which the windows palette has been set, and the mapping of the shadow |
|
2155 surface to the new palette. This is especially noticeable during fades. |
|
2156 |
|
2157 To deal with this problem, we can copy a predetermined portion of the |
|
2158 full palette, and use that as the limited palette. This allows colors |
|
2159 to fade smoothly as the remapping is very similar on each palette change. |
|
2160 Unfortunately, this breaks applications which partition the palette into |
|
2161 distinct and widely varying areas, expecting all colors to be available. |
|
2162 |
|
2163 I'm making them both available, chosen at compile time. |
|
2164 If you want the chunk-o-palette algorithm, define SIMPLE_COMPRESSION, |
|
2165 otherwise the sort-by-diversity algorithm will be used. |
