Color
1.4.1 / 2010.02.03¶ ↑
-
Imported to github.
-
Converted to Hoe 2.5 spec format.
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 theColor
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 withColor
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 theColor
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. 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.
