推荐答案

有一些本机PHP函数可以执行此操作，但是您实际上不应该在PHP中执行此操作.

There are a few native PHP functions to do this, but you really shouldn't be doing this in PHP.

您将需要通过创建空白图像画布. imagecreatetruecolor，将其保存到服务器目录中，并使用某些本机映像功能(例如imagefilledpolygon)进行填充. PHP内置了您可以使用的imagefilled___函数.

You would need to create a blank image canvas via. imagecreatetruecolor, save it into the the directory of the server and fill it using some native image function such as imagefilledpolygon. PHP has built in imagefilled___ functions you can use.
