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

sathsy · August 5, 2022, 3:48pm

Hi,

We have an application which generates a pdf file from a word template.
Implementation:
Our application listens to an oracle message queue which contains information about the file details.
This file is a .doc template which is stored in S3 bucket. Based on the file information, we fetch the template using a rest client and convert it to ASPOSE PDF document replacing with the data and attachment tags and then store the generated pdf document to the S3 bucket. The UI reads the PDF doc from S3, where all the fonts and formats aredifferent from the initial template .doc we use in higher ENV.
The same is working fine in local ENV.

@ravishat Could you please attach the source template and output PDF here for testing? We will check the issue and provide you more information.
Also please note that Aspose.Words should have access to the font files when its performing DOC to PDF conversion. Please check the Specify TrueType Fonts Location and Aspose.Words Integration in AWS Lambda articles.

Thank you for your prompt response! I apologize for not including the tech-stack earlier. Here are the details

Language : Java 1.8
PDF generating service (QA environment): PCF

Here is the code snippet I have used in my code to point to a fonts folder

String path = “src/main/resources/fonts”;
FontSettings.getDefaultInstance().setFontsFolder(path, false);

Template file : Template.docx (61 KB)
Generated Pdf : GeneratedPDF.pdf (48.9 KB)

@ravishat Thank you for additional information. It looks like fonts used in your source document are not available in the environment where the conversion is performed. In this case Aspose.Words substitutes the fonts that are not available. You can implement IWarningCallback to get a notification when font substitution is performed.

Hi Alexey,

I work with Ravisha. Based on your suggestion, we did IWarningCallback. There is no log of any substitution.

As previously mentioned we have sent the fonts folder (we use Aspose words Java and currently evaluating Aspose PDF java).

Our application is a Spring Boot app hosted on a PCF platform in a linux container (if that helps)

String path = new ClassPathResource("/fonts").getFile().toString()
FontSettings.getDefaultInstance().setFontsFolder(path, false);

The output PDF document has a totally different font than the source word document. (Word Document has simple Times New Roman, the output PDF file contains, the following set of fonts: (image attached)

Any help would be greatly appreciated.

alexey.noskov · July 29, 2022, 6:26am

@sathsy As I can see the output PDF document attached by @ravishat is produced by Aspose.PDF not by Aspose.Words. Also, in your screenshot I see that Fanwood font is used in output PDF. This for is the last resort font used by Aspose.Words when it cannot find any other fonts in the environment. In this case Aspose.Words should warn about font substitution, if IWarningCallback is properly implemented and set. For example see the following code:

// You can use this code to check what fonts are available in your environment. 
for (FontSourceBase src : FontSettings.getDefaultInstance().getFontsSources())
{
    for (PhysicalFontInfo fontInfo : src.getAvailableFonts())
        System.out.println(fontInfo.getFullFontName());
}

// Open document
Document doc = new Document("C:\\Temp\\in.docx");
// Set warning callback
doc.setWarningCallback(new FontSubstitutionWarningCollector());
// Save the output document.
doc.save("C:\\Temp\\out.pdf");

private static class FontSubstitutionWarningCollector implements IWarningCallback {

    public void warning(WarningInfo info) {
        if (info.getWarningType() == WarningType.FONT_SUBSTITUTION)
            System.out.println(info.getDescription());
    }
}

Hello @alexey.noskov,

We have added the code as per your suggestion. What’s weird is that when its printing the fonts it printed the times new roman but then it complains again that its not finding it.

Here is the code snippet and the corresponding logs.

public Document extractData(ClientHttpResponse response) throws IOException {
    try {
        String path = new ClassPathResource("/fonts").getFile().toString();
        FontSettings fontSettings = new FontSettings();
        FolderFontSource folderFontSource = new FolderFontSource(path, true);
        Document document = new Document();
        document.setFontSettings(fontSettings);
        SystemFontSource systemFontSource = (SystemFontSource)
                document.getFontSettings().getFontsSources()[0];
        for (String systemFontFolder : SystemFontSource.getSystemFontFolders()) {
            log.info("Here is your System Font Folder" + systemFontFolder);
        }			document.getFontSettings().getSubstitutionSettings().getDefaultFontSubstitution().setEnabled(false);
        document.getFontSettings().setFontsSources(new FontSourceBase[] { systemFontSource, folderFontSource });
        document.setFontSettings(fontSettings);
        document = new Document(response.getBody());
        FontInfoCollection fontInfos = document.getFontInfos();
        document.setWarningCallback(new AsposeDocumentToPDDocumentConverter.FontSubstitutionWarningCollector());
        log.info("printing document font information AFTER loading options");
        log.info("***********************************************************************************");
        fontInfos.forEach(fontInfo -> printFontInfo(fontInfo));
        log.info("***********************************************************************************");
        return document;
    }
    catch (Exception cause) {
        throw new IOException(cause);
    }
}

private void printFontInfo(FontInfo fontInfo) {
    log.info("AltName:" + fontInfo.getAltName());
    log.info("Name:" + fontInfo.getName());
    log.info("Font Family:" + fontInfo.getFamily());

}

@ravishat Thank you for additional information. However, in your code you use Document.getFontInfos() this property returns font info read from fontTable from the document, i.e. fonts used in the document. To get fonts available in your environment, you should use code like this:

// Set font settings
document.setFontSettings(fontSettings);
// Print the fonts available in the font sources specified in the document font settings.
for (FontSourceBase src : document.getFontSettings().getFontsSources())
{
    for (PhysicalFontInfo fontInfo : src.getAvailableFonts())
        System.out.println(fontInfo.getFullFontName());
}

Hello @alexey.noskov
I have tried printing with the above. Here are the logs.
After analyzing more we dont have any fonts at the locations which got printed in the logs. Also, we don’t have permissions to access those paths to place the font folder as this is a PCF env and we are using .jar file to deploy. Could you please suggest on how we can get the fonts loaded ?

@ravishat Thank you for additional information. As I can see from your log, the only available font family in your environment is DejaVu. Since, there are no other available fonts, Aspose.Words substitutes the fonts in your document with DejaVu.
Please make sure the fonts folder you have specified in the code is available and accessible by your code.

sathsy · August 2, 2022, 4:43am

Hi Alex,
Based on your recommendation we did print the system font sources and as suspected these are the only fonts available in the system

Couple of points to reiterate:

We have a spring boot application.
we host it on PCF
we package all windows fonts (for testing purposes) as part of the boot application and we verified that it is in fact packaged.
How do we add the fonts to System font sources.

Currently we have something like this:

String path = new ClassPathResource("/fonts").getFile().toString();
FontSourceBase[] fontsSources = document.getFontSettings().getFontsSources();
//Aspose.words Document     
document.setFontSettings(fontSettings);

Also tried this:

fontSettings.getDefaultInstance().setFontsSources(
				new FontSourceBase[] { new FolderFontSource(folder, true, 1), new SystemFontSource(0) });`

None of the above made any difference.

Is there a documentation with PCF /linux stack and loading folderfontsource?

alexey.noskov · August 2, 2022, 4:58am

@sathsy There are no additional requirement for specifying a folder fonts source in Linux. Please see our documentation to learn how to specify fonts folder location.
In your code you specify fonts folder properly, the problem might occur because folder is not accessible. So please check the following in your code:

Make sure the specified fonts folder exists;
Make sure folder is not empty;
Make sure you can read files from the specified folder.

As an alternative, you can load additional fonts from steam or from memory.

sathsy · August 2, 2022, 5:13am

Thank you. I can list the TTF/TTC font files from the packaged jar while deployed to PCF.

I did take a look at StreamFontSource and MemoryFontSource. I might have to look at StreamFontSource for all the fonts used in the source word document.

I wonder what the other poster did to get PCF to read the custom packaged fonts folder (LocalFontSource, setting priority to FontFolderSource - I have tried many options).

There seems to be some nuance with how spring boot + PCF reads the folder of fonts.

alexey.noskov · August 2, 2022, 8:08am

@sathsy Thank you for additional information. Unfortunately, Aspose.Words does not read fonts packed into JAR. So in your case you should either copy the fonts into the OS file system or use StreamFontSource or MemoryFontSource to get fonts from your JAR file and provide them to Aspose.Words.

sathsy · August 2, 2022, 2:11pm

@alexey.noskov our document could have multiple fonts. Having looked at the StreamFontSource, is there an elegant way not to mention every single font?

I could get all the fonts present in the document using:
Document.getFontInfos()
Would it be then loading each of those fonts used in the document using:

private static class StreamFontSourceFile extends StreamFontSource  {
    public FileInputStream openFontDataStream() throws Exception {
        return new FileInputStream(getFontsDir() + "**Kreon-Regular.ttf**");
    }
}

looks a little cumbersome.

alexey.noskov · August 2, 2022, 6:59pm

@sathsy You can read the fonts once from your folder and set fonts sources as an array. For example see the following code:

FontSettings.getDefaultInstance().setFontsSources(getFontsFromFolder("C:\\Temp\\fonts"));

private static FontSourceBase[] getFontsFromFolder(String foldePath) throws Exception {
    File folder = new File(foldePath);
    File[] listOfFiles = folder.listFiles();

    ArrayList<FontSourceBase> fonts = new ArrayList<FontSourceBase>();

    for (int i = 0; i < listOfFiles.length; i++) {
        if (listOfFiles[i].isFile()) {
            fonts.add(new StreamFontSourceFile(listOfFiles[i].getAbsolutePath()));
        }
    }

    FontSourceBase[] fontsArray = fonts.toArray(new FontSourceBase[fonts.size()]);
    return fontsArray;
}

private static class StreamFontSourceFile extends StreamFontSource  {
    public StreamFontSourceFile(String fontFilePath)
    {
        mFontFilePath = fontFilePath;
    }

    public FileInputStream openFontDataStream() throws Exception {
        return new FileInputStream(mFontFilePath);
    }

    private String mFontFilePath;
}

You can also add system font source as the first item into the array to use system fonts too.

sathsy · August 3, 2022, 4:30am

Thank you. We used the above Streamsource implementation and verified that the folder is accessible in the environment.

try
{
	//getFontsFromFolder is from the above implementation given by Alexey
	fontSettings.setFontsSources(getFontsFromFolder(path));
	document.setFontSettings(fontSettings);
	PdfSaveOptions pdfSaveOptions = new PdfSaveOptions();
	pdfSaveOptions.setEmbedFullFonts(true);
	document.save(pdfOutputStream, pdfSaveOptions);
	log.info("Getting font info after saving as PDF....");

}
catch (Exception e)
{
	log.info("Error converting to PDF generatePDFAspose::" + e);
}

We still have the same issue where font substitution happens and i see the message from warning call back and the generated PDF has only the following fonts

It still only has the last resort fanwood fonts!

Is there anything else I am missing when document.save(pdfOutputStream,pdfSaveOptions); is called. It doesnt matter if I embed the fonts or not.

Also before saving it as PDF, i tried printing all the document fonts and system fonts (stream source fonts) and it has all my packaged fonts.

Mystery continues!!

alexey.noskov · August 3, 2022, 5:49am

@sathsy Could you please attach your input document and the fonts, which are packaged into your JAR? We will try to emulate your situation and reproduce the problem.
Also, could you please try copying the packaged fonts into a temporary folder in your environment and use this temporary folder as fonts folder source?

sathsy · August 4, 2022, 6:08am

Here is the code:

public static void copyFontsToCFTMPFolder(String foldePath, boolean... writeFiles) throws Exception {
    try {
        FontSourceBase[] originalFontSources = FontSettings.getDefaultInstance().getFontsSources();
        File srcFolder = new File(foldePath);
        File destDir = new File(TMP_DIR); // defined and is one of system fonts folder in PCF
        log.info("Is TMP_DIR writable" + destDir.canWrite());
        FileUtils.forceMkdir(new File(TMP_DIR + "/fonts"));
        FileUtils.copyDirectory(srcFolder, new File(destDir + "/fonts"));
    }
    catch (Exception | IOException e) {
        log.info("Error copying folder" + e);
    }
}

In the subsequent code:

 SystemFontSource systemFontSource = (SystemFontSource)template.getFontSettings().getFontsSources()[0];

FolderFontSource folderFontSource = new FolderFontSource(TMP_DIR + "/fonts", false, 100);
template.getFontSettings().setFontsSources(new FontSourceBase[] { systemFontSource, folderFontSource });
log.info("Now lenght of systemFontSource:::::>" + template.getFontSettings().getFontsSources().length); // prints the length as 2 with one of my folder source

When I try to print the fonts in both the folders:

public static void printFontInfo1(Document document) {
    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());
    }
}

I did verify the folder is writable and individually listed the fonts in code and verified the folder listing SSH’ing to my PCF app.
