PDF file fonts and formats not matching the word format provided after generation

sathsy · August 5, 2022, 3:17pm

@alexey.noskov I have just attached the bare minimum fonts I am copying for testing purposes.

per my latest changes:

public static void printFontInfo1(Document document)
{
    log.info("Number of system font resources" + document.getFontSettings().getFontsSources().length);
    for (FontSourceBase src : document.getFontSettings().getFontsSources())
    {
        log.info("The source is::::>" + src.toString());
        log.info("Priority is:::>" + src.getPriority());
        log.info("Type of font folder is:::>" + src.getType());
        for (PhysicalFontInfo fontInfo : src.getAvailableFonts())
            log.info(fontInfo.getFullFontName());
    }
}

the corresponding log: (See the fonts size when I do src.getAvailableFonts() is always 0. While the directory has the fonts I have attached here. The other logs come through fine (in fact I set the priority to 100 for debug purposes)

    2022-08-05 08:11:20.144  INFO 22133 --- [enerContainer-1] c.s.s.o.p.c.a.DocumentResponseExtractor  : The source is::::>com.aspose.words.FolderFontSource@25b75231

and from that point onwards, the final fallback font Fanwood is used.

BTW, after trying many different options, this is what I use to set the folderfont source (remember, it doesnt matter if I use Streamfontsource all the same result)

try
{
    log.info("generatePDFAspose setting fontsettings");
    log.info("Calling the warningcallback in PDFBoxPDFGenerator generatePDFAspose");
    FontSettings fontSettings = new FontSettings();

    template.setWarningCallback(new AsposeDocumentToPDDocumentConverter.FontSubstitutionWarningCollector());
    PdfSaveOptions pdfSaveOptions = new PdfSaveOptions();
    pdfSaveOptions.setFontEmbeddingMode(0);
    pdfSaveOptions.setEmbedFullFonts(true);
    pdfSaveOptions.setUseCoreFonts(false);

    fontSettings.setFontsSources(
            new FontSourceBase[] {
                    new FolderFontSource(TMP_DIR + "/fonts", true, 100),
            }
    );
    template.setFontSettings(fontSettings);

    log.info("Printing system folders...after setting template.setFontSettings....");
    printFontInfo1(template);

    template.save(pdfOutputStream, pdfSaveOptions);

    template.setWarningCallback(new AsposeDocumentToPDDocumentConverter.FontSubstitutionWarningCollector());
}
catch (Exception e)
{
    log.info("generatePDFAspose()" + e);
}

Please let me know if you have more questions.

@sathsy Thank you for additional. The problem is with your fonts. They all are broken.

Looks like font files were broken either upon packaging them into JAR file, or upon extracting them.

@alexey.noskov, the picture is not accessible. Can you please reattach it?

sathsy · August 5, 2022, 3:49pm

Ok, I am validating the font files from my mac FontViewer and copying them again.

alexey.noskov · August 5, 2022, 3:50pm

@sathsy I have changed the topic ownership. Now you should be able to see the image. It is a simple Windows error message screenshot that states “The requested file is not a valid font file”.

sathsy · August 5, 2022, 3:57pm

Do you think that is the reason that the src.getAvailableFonts in the above attached code returns no fonts while regular directory listing in code is able to list / return the fonts?

alexey.noskov · August 5, 2022, 4:10pm

@sathsy Aspose.Words simply does not recognize the listed files as valid fonts. So they are not listed. FontSourseBase.getAvailableFonts returns the list of fonts Aspose.Words is able to read as fonts, but not a list of files.

sathsy · August 5, 2022, 4:37pm

@alexey.noskov thanks for working with us persistent.

So after validating the fonts in my local MAC, the fonts are listed fine. However in PCF it is the same story.

1st log is from local: (expected to miss a couple of fonts)

and here is the PCF where the fonts are not being read again!!!

@alexey.noskov - Good news. The culprit was maven!!! when filtering resources it was corrupting the TTF / TTC files. With this simple configuration, we are able to embed fonts and get the correct fonts in PCF.

For anyone in future having this issue, here is what is needed if you are using maven:

<plugin>
	<artifactId>maven-resources-plugin</artifactId>
	<version>3.2.0</version>
	<configuration>
		<encoding>UTF-8</encoding>
		<nonFilteredFileExtensions>
			<nonFilteredFileExtension>ttf</nonFilteredFileExtension>
			<nonFilteredFileExtension>ttc</nonFilteredFileExtension>
		</nonFilteredFileExtensions>
	</configuration>
</plugin>

Other than that, reference the code to add a LocalFontSource and that should do the trick:

fontSettings.setFontsSources(
    new FontSourceBase[] {
            new FolderFontSource(TMP_DIR + "/fonts", true, 100),
    }
);
document.setFontSettings(fontSettings); //Aspose word document - this is needed before converting to PDF.

Thank you so much for your constant support and help @alexey.noskov. Much appreciated!
