php +html怎么自动\生成coords坐标?

您好！关于您的问题，您可以使用如下的代码片段自动生成coords坐标：

<?php
function get_coords($img_path, $shape) {
    $width = $shape[0];
    $height = $shape[1];
    $coords = '';

    // loop through each pixel
    for ($y = 0; $y < $height; $y++) {
        for ($x = 0; $x < $width; $x++) {
            $rgb = imagecolorat($img_path, $x, $y);
            $color = imagecolorsforindex($img_path, $rgb);

            // if pixel is not white, add coords
            if ($color['red'] < 255 || $color['green'] < 255 || $color['blue'] < 255) {
                $coords .= "$x, $y, ";
            }
        }
    }

    // remove last comma and space
    $coords = substr($coords, 0, -2);

    return $coords;
}

使用方法：

<?php
$img_path = 'path/to/image.png';
$shape = getimagesize($img_path);
$coords = get_coords($img_path, $shape);
echo $coords;
?>

希望这能够帮到您！
