Hello,

Thank you for your inquiry.
I have tested the Word document you provided, but I was unable to reproduce the issue you mentioned. I have attached the result file from my testing for your reference.
Furthermore, I examined the embedded fonts in the PDF file you provided and found that the font used is not Calibri. However, the Word source document specifies Calibri as the font. Therefore, I kindly suggest checking your testing environment for the presence of the Calibri font. If it is not installed, please install it before conducting further tests. If the font is already installed, please ensure that you have the necessary permissions to access the font file.
If you require any additional assistance or have further questions, please feel free to reach out.

Sincerely,
Annika

Hi,
Thanks for quick answer.
This issue happen as part of regression tests. With old library (11.7.0) we don't see issue, problem appear only after upgrade to 12.1.0. Code executed on same environment, just library was changed.

Thanks,

Hello,

Thank you for your feedback.
Based on the information you provided, I have checked and found that the Calibri font is not installed in your Linux environment. Starting from Spire.Doc for Java 12.1.0, we have enhanced font detection, which may have caused the issue you mentioned.
In Spire.Doc, when converting Word to PDF, you can specify the font file path. To resolve this issue without installing the font in the testing environment, please place the Calibri font file used in your Word document into the "Fonts" folder and use the following code for testing:

Code: Select all

// Create a new Document object
Document document = new Document();
// Load the document from the specified file, automatically detecting the file format
document.loadFromFile("hebrew.docx", FileFormat.Auto);
// Set the custom fonts folder path
document.setCustomFontsFolders("Fonts");
// Save the document to a PDF file at the specified path using the PDF format
document.saveToFile("output/result-12.1.16.pdf", FileFormat.PDF);

This way, you won't need to install the font in the testing environment.

Hi,
Thanks for quick answer.
We are not able to get proper pdf with Hebrew using next code:

Code: Select all

    public Result convert(Http.Request request) throws Exception {
        Http.MultipartFormData<Files.TemporaryFile> body = request.body().asMultipartFormData();
        Http.MultipartFormData.FilePart<Files.TemporaryFile> file = body.getFile("file");
        Document document = new Document();
        document.loadFromFile(file.getRef().path().toString());
        try {
            String path = "/usr/local/dealhub/conf/resources/fonts/";
            if (new File(path).isDirectory()) {
                log.info("Adding {} to spire.doc fonts folder", path);
                document.setCustomFontsFolders(path);
                log.info("Added {} to spire.doc fonts folder", path);
            }
        } catch (Exception ex) {
            log.error("Cannot setCustomFontsFolders", ex);
        }
        ByteArrayOutputStream out = new ByteArrayOutputStream();
        document.saveToStream(out, FileFormat.PDF);
        return ok(new ByteArrayInputStream(out.toByteArray()))
                .withHeader(Http.HeaderNames.CONTENT_TYPE, MimeTypesExtended.X_DOWNLOAD)
                .withHeader(Http.HeaderNames.CONTENT_DISPOSITION, "attachment; filename=\"test.pdf\"");
    }

Hello,

Thank you for your feedback.
I see that you are using the custom font file with the font "Liberation Sans". I have tested this font with the latest version of Spire.Doc and found that it does not properly support Hebrew characters, resulting in them appearing as garbled text. I have logged the issue into our bug tracking system with the ticket number SPIREDOC-10280. Our development team will investigate and fix it. Once it is resolved, I will inform you in time. Sorry for the inconvenience caused.

Code: Select all

bash-5.2# fc-list | grep calibri
/usr/share/fonts/fonts-master/calibril.ttf: Calibri,Calibri Light:style=Light,Regular
/usr/share/fonts/fonts-master/calibrib.ttf: Calibri:style=Bold
/usr/share/fonts/fonts-master/calibrii.ttf: Calibri:style=Italic
/usr/share/fonts/fonts-master/calibrili.ttf: Calibri,Calibri Light,Calibri Light Italic:style=Light Italic,Italic
/usr/share/fonts/fonts-master/calibri.ttf: Calibri:style=Regular

Hello,

Thank you for your feedback.
I tested the Word document you provided earlier using Spire.Doc for Java Version:12.1.16 in a linux environment, but it still did not reproduce your problem. The fonts are still using Calibri. is this the version you tested with? If not, please upgrade to this version first. I am attaching my test code and result file for your reference.
Also, are you testing in a docker container?

Hi,
We've used provided code (SpireDoc for Java 12.1.16):

Code: Select all

        Document document = new Document();
        document.loadFromFile(file.getRef().path().toString(), FileFormat.Auto);
        ByteArrayOutputStream out = new ByteArrayOutputStream();
        document.saveToStream(out, FileFormat.PDF);


and getting error:

Code: Select all

Caused by: java.lang.IllegalArgumentException: Cannot detect current file type
   at com.spire.doc.Document.spr???�(Unknown Source)
   at com.spire.doc.Document.spr???�(Unknown Source)
   at com.spire.doc.Document.spr???�(Unknown Source)
   at com.spire.doc.Document.loadFromFile(Unknown Source)
   at controllers.test.SpireDocConversion.convert(SpireDocConversion.java:28)


Without FileFormat.Auto conversion happen, but with Hebrew problem.
Calibri fonts installed as system fonts and accessible from Java.

Please help to resolve issue.

Full code, test file, env details in attached file.

Hello,

Thanks for your feedback.
I'm sorry to tell you that we still haven't reproduced the problem you mentioned. Have you updated the version to the latest Spire.Doc 12.1.16(https://www.e-iceblue.com/Download/doc-for-java.html)? Since we are on Spring Festival vacation (until 2024-2-18) and lack the environment to reproduce the problem, we will further investigate your problem when we return to the office. Thank you for your understanding.
