%description
Provides ability to create color palettes from image files. It offers
control over the type of color palette to derive from an image
(qualitative, sequential or divergent) and other palette properties.
Quantiles of an image color distribution can be trimmed. Near-black or
near-white colors can be trimmed in RGB color space independent of
trimming brightness or saturation distributions in HSV color space.
Creating sequential palettes also offers control over the order of HSV
color dimensions to sort by. This package differs from other related
packages like 'RImagePalette' in approaches to quantizing and extracting
colors in images to assemble color palettes and the level of user control
over palettes construction.
