== Color 1.4.0 / 2007.02.11
* Merged Austin Ziegler's color-tools library (previously part of the Ruby
PDF Tools project) with Matt Lyon's color library.
- The HSL implementation from the Color class has been merged into
Color::HSL. Color is a module the way it was for color-tools.
- A thin veneer has been written to allow Color::new to return a Color::HSL
instance; Color::HSL supports as many methods as possible that were
previously supported by the Color class.
- Values that were previously rounded by Color are no longer rounded;
fractional values matter.
* Converted to hoe for project management.
* Moved to the next step of deprecating Color::Name values; printing a
warning for each use (see the history for color-tools 1.3.0).
* Print a warning on the access of either VERSION or COLOR_TOOLS_VERSION; the
version constant is now COLOR_VERSION.
* Added humanized versions of accessors (e.g., CMYK colours now have both #cyan
and #c to access the cyan component of the colour; #cyan provides the value
as a percentage).
* Added CSS3 formatters for RGB, RGBA, HSL, and HSLA outputs. Note that the
Color library does not yet have a way of setting alpha opacity, so the
output for RGBA and HSLA are at full alpha opacity (1.0). The values are
output with two decimal places.
* Applied a patch to provide simple arithmetic colour addition and subtraction
to Color::GrayScale and Color::RGB. The patch was contributed by Jeremy
Hinegardner <jeremy@hinegardner.org>. This patch also provides the ability to
return the maximum RGB value as a grayscale colour.
* Fixed two problems reported by Jean Krohn <jb.krohn@free.fr> against
color-tools relating to RGB-to-HSL and HSL-to-RGB conversion. (Color and
color-tools use the same formulas, but the ordering of the calculations is
slightly different with Color and did not suffer from this problem;
color-tools was more sensitive to floating-point values and precision
errors.)
* Fixed an issue with HSL/RGB conversions reported by Adam Johnson
<adam.sven.johnson@gmail.com>.
* Added an Adobe Color swatch (Photoshop) palette reader,
Color::Palette::AdobeColor (for .aco files only).
== Color 0.1.0 / 2006.08.05
* Added HSL (degree, percent, percent) interface.
* Removed RGB instance variable; color is managed internally as HSL floating
point.
* Tests!
== color-tools 1.3.0
* Added new metallic colours suggested by Jim Freeze <jfn@freeze.org>. These
are in the namespace Color::Metallic.
* Colours that were defined in the Color namespace (e.g., Color::Red,
Color::AliceBlue) are now defined in Color::RGB (e.g., Color::RGB::Red,
Color::RGB::AliceBlue). They are added back to the Color namespace on the
first use of the old colours and a warning is printed. In version 1.4, this
warning will be printed on every use of the old colours. In version 1.5,
the backwards compatible support for colours like Color::Red will be
removed completely.
* Added the Color::CSS module, color/css or Color::CSS that provides a name
lookup of Color::RGB-namespaced constants with Color::CSS[name]. Most of
these colours (which are mirrored from the Color::RGB default colours) are
only "officially" recognised under the CSS3 colour module or SVG.
* Added the Color::HSL colour space and some helper utilities to Color::RGB
for colour manipulation using the HSL value.
* Controlled internal value replacement to be between 0 and 1 for all
colours.
* Updated Color::Palette::Gimp to more meaningfully deal with duplicate named
colours. Named colours now return an array of colours.
* Indicated the plans for some methods and constants out to color-tools 2.0.
* Added unit tests and fixed a number of hidden bugs because of them.
== color-tools 1.2.0
* Changed installer from a custom-written install.rb to setup.rb
3.3.1-modified.
* Added Color::GreyScale (or Color::GrayScale).
* Added Color::YIQ. This colour definition is incomplete; it does not have
conversions from YIQ to other colour spaces.
== color-tools 1.1.0
* Added color/palette/gimp to support the reading and use of GIMP color
palettes.
== color-tools 1.0.0
* Initial release.
