strange font problem -- I think

Hi

Attached is a PDF that renders strangely with PDFBox when converting to an image. The dots come out as little vertical lines.

I am on OS X using PDFBox 1.8.2.

I suspect the issue is that the Dingbats font isn't loaded for some reason. I tried to get the Dingbats font set loaded into my document as follows

		pdf = PDDocument.load(fileName);
		 PDTrueTypeFont.loadTTF(pdf, font.openStream());

where:

- fileName is the attached PDF file
- font is a URL to my ZapDingbats.ttf file (I tried it both ways using resource loading and an explicit path to the the file)

This call causes the following error

java.lang.NullPointerException
	at org.apache.pdfbox.pdmodel.font.PDTrueTypeFont.loadDescriptorDictionary(PDTrueTypeFont.java:409)
	at org.apache.pdfbox.pdmodel.font.PDTrueTypeFont.loadTTF(PDTrueTypeFont.java:201)
	at org.apache.pdfbox.pdmodel.font.PDTrueTypeFont.loadTTF(PDTrueTypeFont.java:177)
	at org.apache.pdfbox.pdmodel.font.PDTrueTypeFont.loadTTF(PDTrueTypeFont.java:158)


I am wondering if this is a bug, or have i missed something obvious?

thanks
graham

Your pdf didn't make it due to some restirctions to the mailing list.

It's not possible to load missing fonts afterwards

I guess the font is embbeded and can't be loaded because of an known issue [1].
It's solved and will be part of our next major release, which isn't yet
scheduled.
