How can I provide a RGBA png file to OpenAI PHP library
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
<?phprequire __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。
