Hi,

I saw sample program described in https://www.e-iceblue.com/news/Spire.PD ... .10.7.html
Could you provide sample code in case of converting form a HTML string to PDF ?

And when using Chrome plugin , shoud I need to get Chrome plugin files and store them in local enviroment like qt plugin ?

Thanks

Hello,

Thanks for your inquiry.
Sorry, the current new method just supports converting a HTML file directly, for your situation, you can first convert your HTML string into an HTML file. Anyway, regarding converting Html string requirement, we will add it as an overload feature, it was logged on the ticket SPIREPDF-7165, once it is available, we will let you know asap.

In addition, when using the new method, it is necessary to ensure that there is the Chrome plugin on the running environment and have the access permissions. I have uploaded a simple example project for your reference. If you have any further questions, please feel free to provide feedback.

Hello.
I'm a colleague of noishiki's.
Since noishiki is not here, I would like to ask an additional question regarding this matter.
When using the sample code websocket, an error is output in the onClose method of WebSocketServiceImpl.
"Web socket connection closed CLOSED_ABNORMALLY"
Can I get some sample code that avoids the error?
Or is it okay to ignore this error?

[matsufuji]

One more question.
When the html size becomes larger than a certain size, a different error occurs and the connection is closed during PDF conversion.
"Web socket connection closed UNEXPECTED_CONDITION, Buffer overflow"
We would like to be able to convert html that is over 1000 pages into PDF.
Is there a way to convert it into PDF?

Hello, matsufuji

Thanks for your inquiry. The onClose method is a callback method that closes the connection. If you do not want to receive this output exception, you can override this method. As shown in the screenshot below. Additionally, please provide us with your input example HTML document for detailed investigation and analysis. You can upload here or send it to us via email（ Amin.gan@e-iceblue.com ). Thank you in advance.

When I convert the attached html to pdf using the sample code you provided, a "buffer overflow" occurs.
Please check.

Hello,

I am writing to inform you of the latest developments regarding the SPIREPDF-7180. The reason for the exception is that the buffer size is insufficient. Please refer to the screenshot below to set the buffer size. If you have any further questions, please feel free to provide feedback.
