NAME
App::GraphicsColorNamesUtils - Utilities related to Graphics::ColorNames
VERSION
This document describes version 0.007 of App::GraphicsColorNamesUtils (from Perl distribution App-GraphicsColorNamesUtils), released on 2023-12-04.
DESCRIPTION
This distributions provides the following command-line utilities:
FUNCTIONS
colorcode2name
Usage:
colorcode2name(%args) -> [$status_code, $reason, $payload, \%result_meta]Convert RGB color code to name.
This function is not exported.
Arguments ('*' denotes required arguments):
approx => bool
When a name with exact code is not found, find the several closest ones.
code* => color::rgb24
(No description)
Returns an enveloped result (an array).
First element ($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 ($status_code is not 2xx). Fourth element (%result_meta) is called result metadata and is optional, a hash that contains extra information, much like how HTTP response headers provide additional metadata.
Return value: (any)
colorname2code
Usage:
colorname2code(%args) -> [$status_code, $reason, $payload, \%result_meta]Convert color name to code.

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 -lIf 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.
