Fields
zlibsettings: CompressSettings
settings for the zlib encoder, such as window size, ...
auto_convert: AutoConvert
how to automatically choose output PNG color type, if at all
filter_palette_zero: c_uint
If true, follows the official PNG heuristic: if the PNG uses a palette or lower than 8 bit depth, set all filters to zero. Otherwise use the filter_strategy. Note that to completely follow the official PNG heuristic, filter_palette_zero must be true and filter_strategy must be LFS_MINSUM
filter_strategy: FilterStrategy
Which filter strategy to use when not using zeroes due to filter_palette_zero. Set filter_palette_zero to 0 to ensure always using your chosen strategy. Default: LFS_MINSUM
force_palette: c_uint
force creating a PLTE
chunk if colortype is 2 or 6 (= a suggested palette).
If colortype is 3, PLTE
is always created
