Saving word as pdf with custom fonts [Java]

[Robbenpr]

I have a word document with a non standard font in it, when I try to save it as a pdf file the font changes. I would like to keep to original font used in the word document I tried setting the private font paths, this seems to work when running the project in Intellij but not when the jar is ran.

I have the following code

Code: Select all

Document doc = new Document();
doc.loadFromFile(inputPath);
ToPdfParameterList ppl = new ToPdfParameterList();
ppl.setPrivateFontPaths(getPrivateFontPaths());
ppl.isEmbeddedAllFonts(true);
ppl.setMemoryOptimization(true);
ppl.setDisableLink(false);
doc.setJPEGQuality(80);
doc.saveToFile(outputPath, ppl);
doc.close();


private List<PrivateFontPath> getPrivateFontPaths() {
    //String fontLocation=Objects.requireNonNull(this.getClass().getClassLoader().getResource("fonts")).toString();
    String fontLocation="..\\..\\..\\..\\..\\..\\..\\fonts\\";
    List<PrivateFontPath> privateFontPaths = new ArrayList<>();

    String fontName = "myfont";
    privateFontPaths.add(new PrivateFontPath(fontName, PdfFontStyle.Bold.getValue(), fontLocation + "myfont.otf"));

    return privateFontPaths;
}


I believe the issue is with location of the fonts when it is packages as a jar, as I want the otf file embedded in the jar so the fonts will work everywhere the jar is run.

I tried multiple approaches using a relative path, getting the location of the resource in code and using the absolute path where I removed the `file:` prefix, used with prefix.

So how can I add a custom font that is packaged inside the jar?

Hi,

Thanks for your patience!
According to our developers’ feedback, when you package the project, the font path is changed and not accessible, so when you run the jar, the font path is not correct and the method “ToPdfParameterList.setPrivateFontPaths()” will not work.
You can access the file in the jar by calling method ClassLoader.getResourceAsStream(), this will return an InputStream instance of the file, but the method needs a path, instead of a stream. You can write the stream to a file where the jar file is located, and then refer its path in the java code. See following code for reference.

Code: Select all

        private static List<PrivateFontPath> getPrivateFontPaths() throws IOException {
        InputStream is = null;

        try{
            // src/main/resources/fontpath
            is = Test.class.getClassLoader().getResourceAsStream("fontpath/myfont.ttf");
            Files.copy(is, Paths.get("myfont.ttf"));
        }catch (IOException e){
            is.close();
        }

        List<PrivateFontPath> privateFontPaths = new ArrayList<>();
        String fontName = "myfont.ttf";
        privateFontPaths.add(new PrivateFontPath(fontName, PdfFontStyle.Bold.getValue(),  "myfont.ttf"));
        return privateFontPaths;
    }

There is no other alternative solution at present. Maybe we can add the stream as an argument to the constructor of PrivateFontPath, so I added it into our upgrade list with the ticket number SPIREDOC-9004, once it is implemented, I will inform you.
You can try the code I provided or create a folder where the jar is located and put your fonts in it. If you have further questions, just feel free to contact us.

Hi,

Thank you for your response, we will use the workaround you proposed for now.

Adding the inputsteam to the constructor would be great, this way we can also check in the code if the file is found.

If possible I would also like an error or warning message if you are unable to find the font specified by the fontLocation, this would make it easier to find issues with the PrivateFontPaths.

Hi,

Thanks for your feedback.
When the specific font file is not found, our products will find some relate fonts for replacement, to keep the format of the file organized. I have added your idea into our upgrade list with the ticket number SPIREDOC-9006, once it is implemented, I will inform you. Thanks for your suggestion.
If you have other questions related to our products, just feel free to contact us.

Hi,

I have another suggestion related to SPIREDOC-9004 (possibility to use an InputStream instead of a String).

When doing a mailmerge you need to add the path to an xml file:

Code: Select all

MailMerge mailMerge = document.getMailMerge();
mailMerge.executeWidthRegion(pathToXml);


It would also be nice if we can use an InputStream here instead of a String which contains the path, this would avoid too much file IO on the system.

Thanks in advance.

Hi,

Thanks for your feedback.
I have recorded your suggestion into our system with the ticket number SPIREDOC-9054, our developers will do an evaluation, once it is implemented, I will keep you informed. Thanks for your suggestion!

Hi,

Thanks for your patience.
Glad to inform you that we just released Spire.Office for Java 8.6.0, which has implemented the new feature SPIREDOC-9054: the mail merge function supports loading files from streams. See the following code for reference.

Code: Select all

document.getMailMerge().executeWidthRegion(InputStream stream);

Hi,

I tried the new feature SPIREDOC-9054: mail merge function supports loading files from streams.

Code: Select all

String xmlString = "<xml>" + XML.toString(mergeItem.getDataSourceJSON(), "root") + "</xml>";
InputStream inputStream= new ByteArrayInputStream(xmlString.getBytes(StandardCharsets.UTF_8));

MailMerge mailMerge = document.getMailMerge();
mailMerge.executeWidthRegion(inputStream);

I am receiving the correct file, but all the merge fields are empty.
When I use the mailMerge.executeWidthRegion(pathToXml); everything is working fine.

Thanks in advance.

Hi

I appreciate the quick response. My apologies for the inconvenience caused; it was an error on my part. Upon attempting to send you the XML file, I noticed that something was incorrect.

I solved it:

Code: Select all

JSONObject jsonObject = new JSONObject(mergeItem.getDataSourceJSON());
String xmlString = "<xml>" + XML.toString(jsonObject, "root") + "</xml>";
InputStream inputStream= new ByteArrayInputStream(xmlString.getBytes(StandardCharsets.UTF_8));

MailMerge mailMerge = document.getMailMerge();
mailMerge.executeWidthRegion(inputStream);


Thank you.

Hi Robbenpr,

Thanks for your patience.
Glad to inform you that we just released Spire.Office for Java 8.7.2, which has implemented the new feature SPIREDOC-9004, The constructor of PrivateFontPath now supports passing a stream as an argument, and it can also be set using the setter method. Please refer to the following code snippet as an example:

Code: Select all

// constructor
PrivateFontPath(String fontName,InputStream fontStream);
PrivateFontPath(String fontName,int fontStyle,InputStream fontStream);

// setter and getter
setFontStream(InputStream value);
getFontStream();
