Imager::Color is a Perl module with color handling for Imager.

SYNOPSIS

$color = Imager::Color->new($red, $green, $blue);
$color = Imager::Color->new($red, $green, $blue, $alpha);
$color = Imager::Color->new("#C0C0FF"); # html color specification

$color->set($red, $green, $blue);
$color->set($red, $green, $blue, $alpha);
$color->set("#C0C0FF"); # html color specification

($red, $green, $blue, $alpha) = $color->rgba();
@hsv = $color->hsv(); # not implemented but proposed

$color->info();

if ($color->equals(other=>$other_color)) {
...
}

This module handles creating color objects used by imager. The idea is that in the future this module will be able to handle colorspace calculations as well.

new

This creates a color object to pass to functions that need a color argument.

set

This changes an already defined color. Note that this does not affect any places where the color has been used previously.

rgba

This returns the rgba code of the color the object contains.

info

Calling info merely dumps the relevant colorcode to the log.

equals(other=>$other_color)
equals(other=>$other_color, ignore_alpha=>1)

Compares $self and color $other_color returning true if the color components are the same.

Compares all four channels unless ignore_alpha is set. If ignore_alpha is set only the first three channels are compared.

You can specify colors in several different ways, you can just supply simple values:
simple numeric parameters - if you supply 3 or 4 numeric arguments, you get a color made up of those RGB (and possibly A) components.

a six hex digit web color, either RRGGBB or #RRGGBB
an eight hex digit web color, either RRGGBBAA or #RRGGBBAA.
a 3 hex digit web color, #RGB - a value of F becomes 255.
a color name, from whichever of the gimp Named_Colors file or X rgb.txt is found first. The same as using the name keyword.

You can supply named parameters:

red, green and blue, optionally shortened to r, g and b. The color components in the range 0 to 255.

# all of the following are equivalent
my $c1 = Imager::Color->new(red=>100, blue=>255, green=>0);
my $c2 = Imager::Color->new(r=>100, b=>255, g=>0);
my $c3 = Imager::Color->new(r=>100, blue=>255, g=>0);
hue, saturation and value, optionally shortened to h, s and v, to specify a HSV color. 0 new(hue=>120, value=>1, saturation=>0.5);
web, which can specify a 6 or 3 hex digit web color, in any of the forms #RRGGBB, #RGB, RRGGBB or RGB.
my $c1 = Imager::Color->new(web=>#FFC0C0); # pale red
gray or grey which specifies a single channel, from 0 to 255.
# exactly the same
my $c1 = Imager::Color->new(gray=>128);
my $c1 = Imager::Color->new(grey=>128);
rgb which takes a 3 member arrayref, containing each of the red, green and blue values.
# the same
my $c1 = Imager::Color->new(rgb=>[255, 100, 0]);
my $c1 = Imager::Color->new(r=>255, g=>100, b=>0);
hsv which takes a 3 member arrayref, containting each of hue, saturation and value.
# the same
my $c1 = Imager::Color->new(hsv=>[120, 0.5, 1]);
my $c1 = Imager::Color->new(hue=>120, v=>1, s=>0.5);

gimp which specifies a color from a GIMP palette file. You can specify the filename of the palette file with the palette parameter, or let Imager::Color look in various places, typically "$HOME/gimp-1.x/palettes/Named_Colors" with and without the version number, and in /usr/share/gimp/palettes/. The palette file must have color names.

my $c1 = Imager::Color->new(gimp=>snow);
my $c1 = Imager::Color->new(gimp=>snow, palette=>testimg/test_gimp_pal);

xname which specifies a color from an X11 rgb.txt file. You can specify the filename of the rgb.txt file with the palette parameter, or let Imager::Color look in various places, typically /usr/lib/X11/rgb.txt.

my $c1 = Imager::Color->new(xname=>blue) # usually RGB(0, 0, 255)

builtin which specifies a color from the built-in color table in Imager::Color::Table. The colors in this module are the same as the default X11 rgb.txt file.

my $c1 = Imager::Color->new(builtin=>black) # always RGB(0, 0, 0)

name which specifies a name from either a GIMP palette, an X rgb.txt file or the built-in color table, whichever is found first.

channel0, channel1, etc, each of which specifies a single channel. These can be abbreviated to c0, c1 etc.

channels which takes an arrayref of the channel values.

Optionally you can add an alpha channel to a color with the alpha or a parameter.

These color specifications can be used for both constructing new colors with the new() method and modifying existing colors with the set() method.

taskbar-compiz for kde 3.5.7 with colors is a modified taskbar for KDE 3.5.7.

With kde 3.5.7 we can change colors of taskbar.

This taskbar-compiz now folows kde settings for taskbar colors.

Tested with Beryl 0.2.1 and Compiz Fusion from git.

Color::Scheme is a module used to generate pleasant color schemes.

This module is a Perl implementation of Color Schemes 2, a color scheme generator. Start by visitng the Color Schemes 2 web site and playing with the colors.

When you want to generate those schemes on the fly, begin using this modoule. The descriptions herein dont make too much sense without actually seeing the colorful results.

Henceforth, paragraphs in quotes denote documentation copied from Color Schemes 2.

"Important note: This tool doesnt use the standard HSV or HSB model (the same HSV/HSB values ie. in Photoshop describe different colors!). The color wheel used here differs from the RGB spectre used on computer screens, its more in accordance with the classical color theory.

This is also why some colors (especially shades of blue) make less bright shades than the basic colors of the RGB-model. In plus, the RGB-model uses red-green-blue as primary colors, but the red-yellow-blue combination is used here.

This deformation also causes incompatibility in color conversions from RGB-values. Therefore, the RGB input (eg. the HTML hex values like #F854A9) is not exact, the conversion is rough and sometimes may produce slightly different color."

Color::Fade provides a Perl extension for fading text colors.

Color::Fade uses mathematical formulas to take an input string of virtually any length, and virtually any number of colors, and assign an individual color to each character to fade between each of the input colors.

In other words, it makes your sentences look really pretty.

Methods

Fade $string among the colors in @colors, where $string is a string of length greater than zero, and @colors is an array of colors in six byte hexadecimal format, with or without the leading octothorpe. @colors must have at least two elements.

When called in array context, the method returns an array in which each element is of the format:

y

For each character, where xxxxxx is a hexadecimal color code and y is one character from the original string.

When called in scalar context, this array is joined before being returned.

Sparklines are intense, simple, wordlike graphics.
Theres a PHP library for producing sparklines, and even a sparkline web service, but I wanted something I could use to generate sparklines in both Java and JSTL (and I thought it would be a fun project). (Its also worth checking out Whys minimalist python sparklines, which encode the image data directly in the HTML as a data: URI [this library allows you to encode the images as using either data: format or javascript: format (supported by IE) in JSTL])
JSTL examples
< %@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" % >
< %@ taglib prefix="spark" uri="http://www.representqueens.com/taglibs/spark" % >
< c:set var="test" value="5, 35, 22, 19, 16, 10, 4, 33, 9, 12, 27, 36, 22" / >
< img src="< spark:bar name="test" color="red" / >" / >
will produce:
(I think the default size might be a little large).
The "name" attribute specifies the key to find the data (Uses JspContext.findAttribute). It expects the value to be either a List , a Number[], or a String of comma separated int values. Its the only manditory attribute.
The other attributes are width, height, spacing, color, highColor, lastColor, output. You can replace "bar" with "line" to get a linegraph (note: highColor and lastColor are currently not supported for line graphs).
The color attributes can either be a color name (a field name from java.awt.Color), or a HTML hex color (e.g. #ff0000 for red).
Enhancements:
- This release properly URL encodes parameters for server generated sparklines.
- This fixes an issue when using hex specified image colors.
- The tag parameter "background" has been added as a workaround for IE6 PNG transparency.

Color Label is a service menu for KDE based on Color Folder 0.3.4 by HessiJames.

HowTo:

Extract all files and

copy colorlabel into /usr/bin/...

perhaps you need to make it executable chmod 755 /usr/bin/colorlabel

copy colorlabel.desktop to /home/~/.kde/share/apps/konqueror/servicemenus/colorlabel.desktop
