Convert large size html to PDF for Java

[noishiki]

Dear Support teams,

I tried to convert html to pdf using your product but it is not working in case of that html size is over than about 1.2M.
Spire.PDF for Java version is 10.9.0. and working on OS Win11, RAM 16GB, JDK1.8 environment.

the test code is following.

Code: Select all

   try (
       FileInputStream fis = new FileInputStream(Paths.get("C:\\tools\\test1.html").toFile());) {
       String htmlString = IOUtils.toString(fis, "UTF-8");
       String outputFile = "C:\\tools\\test.pdf";
       HtmlConverter.setPluginPath("C:\\tools\\plugins-windows-x64\\plugins");
       HtmlConverter.convert(htmlString, outputFile, true, 1000000, new Size(700, 500), new PdfMargins(0),
               LoadHtmlType.Source_Code);
   } catch (IOException e) {
       e.printStackTrace();
   }


I attached 2 html files, test1.html can be converted to PDF file well, but pdf file is not generated for test2.html with no errors, exceptions.
Do you have any restrictions or options for using HtmlConverter?

thanks.

Hello,

Thanks for your inquiry. I have reproduced your problem using your code. At present, our dev team has researched new conversion methods to replace the use of QT plugins. I have validated your HTML document using the new method and the result is correct. Now, our test team is conducting further testing. Once the test passes, we will provide you with a new fix version and usage instructions. Thank you for your understanding.

Sincerely,

Hello,

Thanks for your inquiry. At present, our test team has reported that there are still some issues with the new methods in Linux systems, and the dev team is working on resolving them. If you only need to verify on the Windows system, we can provide a temporary version for you to test first. We will notify you of the update when the official version is released. If you need a temporary version, I will send it to you via email. Please confirm if you need a temporary version.

I understand your situation. I would like to test the product version , so you don't need to send the test version.
Thanks.

Hi

Do you have any update for this topic ?
And I want to know the performance for new conversion methods.
Actually it takes about 20 seconds to convert 300 Kbytes html, I feel it is slow.
I am happy if it would be much faster than now.

thanks.

Hello,

Thanks for your following up.
We have completed preliminary testing on the new conversion method for converting HTML to PDF. To ensure the reliability of the product, we will conduct further testing. Once the official version is available, we will notify you as soon as possible. The question of conversion efficiency is related to the elements contained in the document itself. The more complex the document, the slower the conversion. You can provide us with some of your testing documents, and we can conduct testing based on the documents you provide and provide you with feedback on the conversion time.

Sincerely,
William

About conversion efficiency survey, please use the html files attached to the first inquiry which I posted here.

Thanks.

Hello,

Thanks for your feedback. Our new method also has a significant improvement in performance. I used the new method to convert the HTML document you provided, which took about 7 seconds. If you have any other questions, please feel free to write to me.
