[ANN] color-tools 1.2.0

Discussion in 'Ruby' started by Austin Ziegler, Jul 1, 2005.

  1. =3D color-tools README
    color-tools is a Ruby library to provide RGB, CMYK, and other colour
    support to applications that require it. It provides 148 named RGB
    colours that are commonly supported and used in HTML, colour
    manipulation operations, and a monochromatic contrasting palette
    generator. Version 1.2 introduces two new colour spaces: GrayScale
    (also known as GreyScale) and YIQ (NTSC).

    The GreyScale colour space has been added primarily to add new
    colour space support for PDF::Writer (PDF documents support CMYK,
    RGB, and Grey device colour spaces). The YIQ colour space has been
    promoted to a full colour class to make future colour management of
    this class easier.

    =3D=3D Download and Installation
    Download color-tools from <http://rubyforge.org/frs/?group_id=3D81>.
    Installing this package is as simple as:

    % ruby setup.rb

    Alternatively, you can use the RubyGem version of color-tools
    available as color-tools-1.2.0.gem from the usual sources.

    =3D=3D color-utils 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.
