NEWS
Changes in Version 1.2-4
o Bug fix for choose_palette() when using palette functions with
optional alpha channels.
Changes in Version 1.2-3
o Alpha channel is preserved in desaturate for named colors (especially
"transparent" and NA). (Reported by Simon Potter.)
o Added alpha argument for all palette functions (see ?rainbow_hcl).
o Small fixups for R CMD check.
Changes in Version 1.2-2
o Names of colors are preserved in hex() and hex2RGB() now. (Reported
by Richard Cotton.)
Changes in Version 1.2-1
o If a new version of the dichromat package (> 1.2-4) with tritan
support is found, this is interfaced in choose_palette().
Changes in Version 1.2-0
o New Tcl/Tk-based GUI for choosing different types of palettes:
qualitative (rainbow_hcl), single-hue sequential (sequential_hcl),
multi-hue sequential (heat_hcl), and diverging (diverge_hcl). The
GUI provides a wide collection of pre-stored palettes, easy
manipulation of the corresponding arguments, illustration through
a broad range of plot types (maps, heatmaps, variations of bar plots,
scatter plots, and many more), emulation of desaturation and
dichromatic vision, loading/saving palettes, etc.
o Bug fix in polarLAB_to_LAB conversion.
o All .Call() calls now with PACKAGE = "colorspace".
o Added some simple tests based on the examples and vignette.
Changes in Version 1.1-1
o Added desaturate() function for removal of chroma in a given
vector of colors.
o Bug fix in HLS_to_RGB conversion for s == 0.
Changes in Version 1.1-0
o Added "sRGB" colorspace.
(Existing "RGB" colorspace is linearized "sRGB".)
o Conversions to and from "HSV" and "HSL" can only occur
from or to "RGB" or "sRGB" (because both "HSV" and "HSL"
are relative colorspaces, meaning relative to a particular
RGB colorspace).
(Converting to or from "RGB" gives a different result
compared to conversion to or from "sRGB".)
o All 'gamma' parameters in all R-level functions have been deprecated.
(The "sRGB" colorspace has implicit gamma.)
Changes in Version 1.0-1
o "Escaping RGBland" paper is now published Computational
Statistics & Data Analysis as doi:10.1016/j.csda.2008.11.033.
Citation and references updated accordingly.
Changes in Version 1.0-0
o new version to accompany the "Escaping RGBland" paper accepted
for publication in Computational Statistics & Data Analysis, see
citation("colorspace")
Changes in Version 0.97
o moved color palettes from vcd to colorspace,
including vignette("hcl-colors")
o added infrastructure for HLS color space
o new CITATION file
