包安装

执行以下命令以获取该包的最新版本

composer require tooleks/php-avg-color-picker

使用示例

<?php

use Tooleks\Php\AvgColorPicker\Gd\AvgColorPicker;

$imageAvgRgbColor = (new AvgColorPicker)->getImageAvgRgbByPath($imagePath);
// or
$imageAvgRgbColor = (new AvgColorPicker)->getImageAvgRgbByResource($gdImageResource);
// or
$imageAvgRgbColor = (new AvgColorPicker)->getImageAvgRgb($imagePath);
// or
$imageAvgRgbColor = (new AvgColorPicker)->getImageAvgRgb($gdImageResource);

// The `$imageAvgRgbColor` variable contains the average color of the given image in RGB format (array)[255, 255, 255].

<?php

use Tooleks\Php\AvgColorPicker\Gd\AvgColorPicker;

$imageAvgHexColor = (new AvgColorPicker)->getImageAvgHexByPath($imagePath);
// or
$imageAvgHexColor = (new AvgColorPicker)->getImageAvgHexByResource($gdImageResource);
// or
$imageAvgHexColor = (new AvgColorPicker)->getImageAvgHex($imagePath);
// or
$imageAvgHexColor = (new AvgColorPicker)->getImageAvgHex($gdImageResource);

// The `$imageAvgHexColor` variable contains the average color of the given image in HEX format (string)"#fffff".

您可以使用计算出的值在图片加载前显示容器中的平均图像颜色。

<div style="background-color: <?= $imageAvgHexColor ?>; width: <?= $imageWidth ?>; height: <?= $imageHeight ?>;">
    <img src="/url/to/the/image.(jpg|jpeg|png|gif)" alt="">
</div>
