题意：将RGBA PNG文件提供给OpenAI的PHP库

问题背景：

I import Orhanerday\OpenAi library to my DALL-E Examples project but when I provide images, I got Invalid input image - format must be in ['RGBA'], got RGB. error. I search for this error on the internet but I got nothing.

我将Orhanerday\OpenAi库导入到我的DALL-E Examples项目中，但当我提供图像时，我遇到了“Invalid input image - format must be in ['RGBA'], got RGB.”的错误。我在网上搜索了这个错误，但没有找到任何有用的信息。

My code looks like 我的代码示例如下

<?php

require __DIR__ . '/vendor/autoload.php'; // remove this line if you use a PHP Framework.

use Orhanerday\OpenAi\OpenAi;

$open_ai_key = getenv("OPENAIKEY");
$open_ai = new OpenAi($open_ai_key);
 
$otter = curl_file_create("C:\Users\dotor\OneDrive\Desktop\dalle-examples\otter.png");
$mask = curl_file_create("C:\Users\dotor\OneDrive\Desktop\dalle-examples\mask.png");

$result = $open_ai->imageEdit([
    "image" => $otter,
    "mask" => $mask,
    "prompt" => "A cute baby sea otter wearing a beret",
    "n" => 2,
    "size" => "256x256",
]);

var_dump($result);

Png files; 图像文件

otter.png;

mask.png;

I need to get a result without any errors, what is an RGBA png file and how can I provide?

我需要得到一个没有任何错误的结果，RGBA PNG文件是什么，我该如何提供？

问题解决：

The A in RGBA stands for Alpha, which is simply a value for opacity. Since this is the type needed for OpenAI, you should convert the plain RGB to RGBA leveraging an existing library. In python, I used the Python Image Library (PIL) convert function to complete this task.

RGBA中的A代表Alpha，它仅仅是一个表示透明度的值。由于这是OpenAI所需要的类型，你应该利用现有的库将普通的RGB转换为RGBA。在Python中，我使用了Python图像库（PIL）的转换函数来完成这个任务。
