Hi.

While I'm using pdf2dom library to convert a PDF file into a web form, I get a stack trace printed out on the standard error, and I can't manage to remove it from the standard error to have it my logs instead. It seems to be because GlyphTable.java has a ex.printStackTrace() on line 77, instead of using the log.error() mechanism.
Is it possible to change this to remove any output to the standard error ?

The stack trace I get is the following:

Starting to love the font domain :D. I have the same issue as reported here: https://stackoverflow.com/questions/5587956/make-adobe-fonts-work-with-css3-font-face-in-ie9, with the due exception that the error happens on IE11.

Basically, the font does not render in IE11 because the font does have a flag called installable embedding set with a restrictive level, which means that the font has restrictions in terms of where can be embedded/used.

Is there a way to change such flag value from the library programmatically?

If not available would this help to be taken as inspiration? https://github.com/hisdeedsaredust/ttembed

I'm unable to use the lib, because one it's dependency has vanished from Maven:

Error:Could not resolve org.jfrog.jade.plugins.common:jade-plugin-common:1.3.8.
Required by: net.mabboud.fontverter:FontVerter:1.2.18 > org.reflections:reflections-maven:0.9.9-RC2

hasExtractedFont stacktraces when font name is null.
Fixed with below. Overriding PdfFontExtractor class to fix the error at the moment.
protected boolean hasExtractedFont(PDFont font) {
for (PDFont fontOn : extractedFonts) {
if (fontOn == null || fontOn.getName() == null)
return false;
if (font == null || font.getName() == null)
return false;
if (fontOn.getName().equals(font.getName()) && fontOn.getClass() == font.getClass())
return true;
}
return false;
}

Hello

Could you help me please. Why converted woff is not valid?

public static byte[] convertTtf2Woff(byte[] ttfFont) throws IOException {
        return FontVerter.convertFont(ttfFont, FontVerter.FontFormat.WOFF1).getData();
    }

I've attached base ttf file in this ticket
Pacifico_ttf.zip

we found a rare case where Pdf2Dom throws an OutOfMemory exception when handling embedded fonts. The stack trace is

You can reproduce the issue with e.g. this PDF file:
http://files.danfoss.com/technicalinfo/dila/17/FRCC.ED.VZH170BG.A6.22.pdf

We were checking the sourcecode and it looks like there is some broken offset in the table, pointing far beyond the actual byte array length (the offset deserialized is 1.338.484.881).

In FontDataInputStream then an array of the length 1.594.834.165 bytes is allocated. Then the method tries to read the data from the stream and receives every time a -1 as result (because the stream is at EoF).

```

public byte[] readBytes(int length) throws IOException {
byte[] bytes = new byte[length];
for (int i = 0; i < bytes.length; i++)
bytes[i] = (byte) in.read();
return bytes;
}

This long array then later on causes issues in Pdf2Dom.

We propose a hotfix that introduces some range check into the readBytes() method, e.g.
    ```
public byte[] readBytes(int length) throws IOException {
        if (in.available() == 0)
            return new byte[0];
        byte[] bytes = new byte[length];
        for (int i = 0; i < bytes.length; i++)
        {
             byte b = (byte) in.read();
            if (b>-1)
                bytes[i] = b;
            else
                return Arrays.copyOf(bytes, i);
        }
        return bytes;
    }

As OutOfMemory Exceptions are hard to deal with once they occured we would like to see a fix for this soon.

Have a nice day

I am trying to analyse fonts files (woff, otf and ttf) and extract metadata information such as font name. For instance, when analysing the attached file JustAFileName.zip, the below code is not able to retrieve the font name information:

FVFont font = FontVerter.readFont(file);
String fontName = font.getName(); // always returns null

So far I have been unable to get the font name for any font I tried to analyse, so my guess is that either there is a bug or all the fonts I tried are somehow "corrupted".

The following error is caught when converting font to WOFF2.

java.lang.NumberFormatException: Value out of range. Value:"11001010" Radix:2

It seems to be an issue with unsigned byte parsing. By default all byte values are signed in java, so the method java.lang.Byte.parseByte can not be used.

Hi,

The following line throws an exception for me
FVFont font = FontVerter.convertFont(ICON_FILE_WOFF2, FontFormat.TTF);

It throws the following exception

I have added the jars for jbrotli-0.5.0 and jbrotli-native-darwin-x86* as i am using a mac.

Kindly help me resolve this issue.

Thank you.

I have an PDF-Document (produced most likely by from LaTex) and the TTF-Fonts embedded there are using Format6SubTable. Dumping them and loading in a browser fails because it looks like none of them supports.

I hacked a bit into your codebase and implemented a normalize() step in CmapTable who creates the standard sub-tables for Mac/Unix/Windows and now fonts are loading the browser.

I'll clean up my code and provide a PR

There are unclosed streams everywhere!
For example:
`

  public byte[] getDirectoryData() throws IOException {
        WoffOutputStream writer = new WoffOutputStream();

        writer.writeString(tag);
        writer.writeInt(offset);
        writer.writeInt(getCompressedData().length - paddingAdded);
        writer.writeInt(tableData.length);
        writer.writeUnsignedInt((int) checksum);

        return writer.toByteArray();
    }

`

It should be like

`

                WoffOutputStream writer = new WoffOutputStream();
		
		try {
			writer.writeString(tag);
			writer.writeInt(offset);
			writer.writeInt(getCompressedData().length - paddingAdded);
			writer.writeInt(tableData.length);
			writer.writeUnsignedInt((int) checksum);
			return writer.toByteArray();
		} finally {
			IOUtils.closeQuietly(writer);
		}

`

getting warning like
"WARN org.fit.pdfdom.FontTable - Error loading font 'FTBUET+Verdana-Bold' Message: FontVerter could not detect the input font's type. class java.io.IOException"
is there any solution for this.
Thank you

convert CFF to OTF using FontVerter and then base64 string and embed to font-face. but it can not work.

Anyone else met this problem?

Can this library read font from base64-encoded String?

CffFontAdapter returns invalid Encoding for following cff fonts:

• LOBVRF+DINPro-Bold.cff
• LOBVRF+DINPro-Light.cff
• LOBVRF+DINPro-Regular.cff

I couldn't find the artifact on Maven Central. This page shows no search results: https://search.maven.org/search?q=g:org.fontverter%20AND%20a:FontVerter%20AND%20v:1.2.22

The Spring Plugins repository seems to include the artifacts of this project, but only some old versions: https://repo.spring.io/plugins-release/org/fontverter/FontVerter/

here is the pdf file, tks
