NAME
App::RGBColorUtils - CLI utilities related to RGB color
VERSION
This document describes version 0.004 of App::RGBColorUtils (from Perl distribution App-RGBColorUtils), released on 2023-12-16.
DESCRIPTION
This distributions provides the following command-line utilities:
FUNCTIONS
mix_2_rgb_colors
Usage:
mix_2_rgb_colors(%args) -> [$status_code, $reason, $payload, \%result_meta]
Mix two RGB colors.
Examples:
Example #1:
mix_2_rgb_colors(color1 => "000000", color2 => "ffffff"); # -> [200, "OK", "7f7f7f", {}]
Example #2:
mix_2_rgb_colors(color1 => "ff0000", color2 => "00ff99"); # -> [200, "OK", "7f7f4c", {}]
This function is not exported.
Arguments ('*' denotes required arguments):
color1* => color::rgb24
(No description)
color2* => color::rgb24
(No description)
Returns an enveloped result (an array).
First element ($status_code) is an integer containing HTTP-like status code (200 means OK, 4xx caller error, 5xx function error). Second element ($reason) is a string containing error message, or something like "OK" if status is 200. Third element ($payload) is the actual result, but usually not present when enveloped result is an error response ($status_code is not 2xx). Fourth element (%result_meta) is called result metadata and is optional, a hash that contains extra information, much like how HTTP response headers provide additional metadata.
Return value: (any)
mix_rgb_colors
Usage:
mix_rgb_colors(%args) -> [$status_code, $reason, $payload, \%result_meta]
Mix several RGB colors together.
Examples:
Example #1:
mix_rgb_colors(colors => ["000000", "ffffff", "99cc00"]); # -> [200, "OK", 889955, {}]
This function is not exported.
Arguments ('*' denotes required arguments):
colors* => array[color::rgb24]

rgb_is_dark
Usage:
rgb_is_dark(%args) -> [$status_code, $reason, $payload, \%result_meta]
Check if RGB color is dark.
Examples:
Example #1:
rgb_is_dark(color => 112211);
Result:
[ 200, "OK", 1, { "cmdline.exit_code" => 0, "cmdline.result" => "RGB color '112211' is dark", }, ]
Example #2:
rgb_is_dark(color => "ffccff");
Result:
[ 200, "OK", 0, { "cmdline.exit_code" => 1, "cmdline.result" => "RGB color 'ffccff' is NOT dark", }, ]

CONTRIBUTING
To contribute, you can send patches by email/via RT, or send pull requests on GitHub.
Most of the time, you don't need to build the distribution yourself. You can simply modify the code, then test via:
% prove -l
If you want to build the distribution (e.g. to try to install it locally on your system), you can install Dist::Zilla, Dist::Zilla::PluginBundle::Author::PERLANCAR, Pod::Weaver::PluginBundle::Author::PERLANCAR, and sometimes one or two other Dist::Zilla- and/or Pod::Weaver plugins. Any additional steps required beyond that are considered a bug and can be reported to me.
