Open the image in text editor, I think you'll find a warning from php there.
在文本编辑器中打开图像，我想你会在那里找到来自 php 的警告。

Removing header('Content-type: image/png');and adding file name to imagepng($new_image,"Test.png",9);, might have solved your issue..
删除header('Content-type: image/png');文件名并将其添加到imagepng($new_image,"Test.png",9);，可能已经解决了您的问题..
and use that image with img tag of HTML. i.e. <img src="Test.png" alt="">
并将该图像与 HTML 的 img 标记一起使用。IE<img src="Test.png" alt="">
