获取数字值 - 通过PHP创建图像

Question

例如，我与JS进行提取： 根据API开发人员的说法，我本人不需要任何PHP。关于如何制作此工作或信息源的任何信息将不胜感激。 （如果有人知道更好的标题，请告诉我）

71562显示了此图像： akblem

33994显示了此图像： emblem2 ，

因此它们是图案，色彩和徽章叠加的组合。

function test () {
    fetch("https://api.examplesite.com/example/Spoons")
        .then(result => result.json())
        .then ((out) => {
            console.log(out.emblem) // out.emblem returns the numeric value
        })
}

console.log输出：

{name: 'Spoons', realmID: 1, realm: 'Albion', emblem: 71562, realmPoints: 123888, …}
bountyPoints: 5
emblem: 71562 //this is the value needed to somehow create the emblem
members: 17
name: "Spoons"
realm: "Albion"
realmID: 1
realmPoints: 123888

标志号应该代表您可以使用JavaScript（精灵，叠加图像）形成的图片，但不知道如何。

我拥有的此信息是：

标志是叠加模板颜色等 我输出的字符串文本 /公会应该足以构建ID 给定正确的图标文件，请与我一起

这是我从API开发人员那里收到的PHP：

<?php
header ('Content-type: image/png');
$emblem = $_GET['emblem'];
$thumbnail = $_GET['thumbnail'];

$hex = dechex($emblem);
$bin = hexbin($hex);
if ($emblem > 65500)
$logo = substr($bin,-18,-9);
else 
$logo = substr($bin,-16,-9);
$logobin = bindec($logo);
$pattern = substr($bin,-9,-7);
$patternbin = bindec($pattern);
$primary = substr($bin,-7,-3);
$primarybin = bindec($primary);
$secondary = substr($bin,-3,3);
$secondarybin = bindec($secondary);
if($patternbin==3)
{
    $secondarybin = 0;
}
$background = imagecreatefrompng("../images/guildshields/$primarybin-$secondarybin-$patternbin-full.png"); 
$img = imagecreatefromgif("../images/guildshields/Emblems/$logobin.gif");
if ($emblem > 65000)
{
$img2 = imagecreatetruecolor(64, 64);
imagealphablending($img2, false);
imagesavealpha($img2, true);
imageCopyResampled($img2, $img, 0, 0, 0, 0, 64, 64, 128, 128);
}
else 
$img2 = $img;
$img2_width = imagesx($img2);
$img2_height = imagesy($img2);
$bg_width = imagesx($background);
$bg_height = imagesx($background);
imagecopy($background, $img2, ($bg_width-$img2_width)/2, ($bg_height-$img2_height)/2, 0, 0, $img2_width, $img2_height);
if ($thumbnail == "true")
{
    $im = $background;
    $width=ImageSx($im); // Original picture width is stored
    $height=ImageSy($im); // Original picture height is stored
    $thumb=imagecreatetruecolor($width/2,$height/2);
    imageCopyResized($thumb,$im,0,0,0,0,$width/2,$height/2,$width,$height);
    imagepng($thumb);
}
else
{
    imagepng($background); 
}

function hexbin($hex)
{
   $bin='';
   for($i=0;$i<strlen($hex);$i++)
       $bin.=str_pad(decbin(hexdec($hex[$i])),4,'0',STR_PAD_LEFT);
       return $bin;
} 
?>

我从API DEV获得的最后一位信息是：

中输出的字符串

这获取了我从API 。 $ emblem = $ _get ['emblem'];

这是从该字符串中获取的所有信息，徽标将保持在字符串的9-16位置

的位置

$bin = hexbin($hex);
if ($emblem > 65500)
$logo = substr($bin,-18,-9);
else 
$logo = substr($bin,-16,-9);
$logobin = bindec($logo);
$pattern = substr($bin,-9,-7);
$patternbin = bindec($pattern);
$primary = substr($bin,-7,-3);
$primarybin = bindec($primary);
$secondary = substr($bin,-3,3);
$secondarybin = bindec($secondary);
