Methods

Name	Description
create_4_bit()	Creates the 4 bit color palette.
create_4_bit_grayscale(min_is_white)	Creates the 4 bit grayscale palette.
create_8_bit()	Creates the 8 bit color palette.
create_8_bit_grayscale(min_is_white)	Creates the 8 bit grayscale palette.
create_monochrome()	Creates a monochrome color palette containing 2 colors only.
get_close_image_palette(image, dest_bounds, entries_count)	Gets color palette from raster image (palletizes image) in case the image does not have one. In case palette exists it will be used instead performing calculations.
get_close_image_palette(image, dest_bounds, entries_count, use_image_palette)	Gets color palette from raster image (palletizes image) in case the image does not have one. In case palette exists it will be used instead performing calculations.
get_close_image_palette(image, entries_count)	Gets color palette from raster image (palletizes image) in case the image does not have one. In case palette exists it will be used instead performing calculations.
get_downscale_palette(image)	Get 256 color palette, composed from upper bits of initial image color values.
get_uniform_color_palette(image)	Get uniform 256 color palette.
has_transparent_colors(palette)	Determines whether the specified palette has transparent colors.
