Description

imagecolorallocatefromstring is a function that will allocate a color based on a string for your PHP GD images.

As of v2.0.0 imagecolorallocatefromstring is part of AgjGd. The implementation now lives in the \AndrewGJohnson\AgjGd class provided by the andrewgjohnson/agjgd package, and this package provides the standalone imagecolorallocatefromstring() function as a thin reverse-compatibility wrapper around it.

New code should call \AndrewGJohnson\AgjGd::imagecolorallocatefromstring() directly.

imagecolorallocatefromstring is an agjgd project.

Examples

// Allocate red with imagecolorallocate() or with imagecolorallocatefromstring() via a string
$red           = imagecolorallocate($im, 0xFF, 0x00, 0x00);
$redFromString = imagecolorallocatefromstring($im, '#FF0000');
$redFromString = imagecolorallocatefromstring($im, '#f00');
$redFromString = imagecolorallocatefromstring($im, 'rgb(255 0 0)');
$redFromString = imagecolorallocatefromstring($im, 'rgb(255, 0, 0)');
$redFromString = imagecolorallocatefromstring($im, 'rgba(255, 0, 0, 1)');
$redFromString = imagecolorallocatefromstring($im, 'rgba(255 0 0 / 100%)');
$redFromString = imagecolorallocatefromstring($im, 'red');

There are other examples included in the GitHub repository and on imagecolorallocatefromstring.agjgd.org.

Usage

With Composer

This project offers support for the Composer dependency manager. You can find the imagecolorallocatefromstring package online on packagist.org.

Install using Composer

Either run this command:

composer require andrewgjohnson/imagecolorallocatefromstring

or add this to the require section of your composer.json file:

"andrewgjohnson/imagecolorallocatefromstring": "^2.0"

This package requires PHP 8.0 or newer, the GD extension and the andrewgjohnson/agjgd package, which Composer installs automatically.

Without Composer

Because imagecolorallocatefromstring() now forwards to the \AndrewGJohnson\AgjGd class, you need both this wrapper and AgjGd. Composer is the recommended way to install them, but you can also require both source files directly:

require_once 'path/to/agjgd/source/AndrewGJohnson/AgjGd.php';
require_once 'source/imagecolorallocatefromstring.php';
