B4J Question B4J program (Non-UI) HTML to image

[hzq200409]

Does anyone know how to convert HTML to image file in B4J program (Non-UI)?

The result of converting to jpg is still not good.

That's because the website doesn't allow CORS. you have to download the img to the local.

并不是这样的。因为这个简单的程序是要作为jserver程序的一部分的。因为jserver程序执行环境并不会登录到桌面。而通过很多次实践发现这个小程序在窗体没有实际渲染HTML的时候根本不会生成任何内容的jpg. 通过f.setVisible(false)即可看出端倪。

It's not ideal. HTML like attachments cannot be displayed.

No, I'm not surprised. That's a big ask, I doubt it would be displayed properly in the Javafx web browser.

At least it displays in its entirety (except for a slight difference in font size and browser rendering). Acquaintance degree is relatively high).
And here's the problem: JEditorPane doesn't seem to render html properly without logging into the desktop environment. The effect can be seen in the annex on the 22nd floor.

As you are looking for something that will run in non-ui, you may find an up to date library that can do what you want, but there would probably be a cost for that.

Finally, I chose the html2canvas library of JS to generate it from the front end and then send it back to the server. If anyone implements it in a jserver backend Non-UI environment, please let me know.?
