John Hewson commented on PDFBOX-1790:
-------------------------------------

This is probably fixed in the latest 2.0 trunk.

>             Project: PDFBox
>          Issue Type: Bug
>          Components: Writing
>    Affects Versions: 1.8.2
>         Environment: Mac 10.7 / Java 6

> I'm attempting to embed a TrueType font using PDFBox, on the Mac, using PDTrueType.loadTTF( PDDocument, InputStream, Encoding ).
> For TrueType fonts originating from Windows (e.g., Tahoma) this works.
> For TrueType fonts originating from the Mac (e.g., Apple Chancery), a NullPointerException is thrown.
>     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)
> I stepped through the code in a debugger. The method PDTrueTypeFont.loadDescriptorDictionary() loops through the cmap table for the font, looking for a cmap with platform ID 3 (Windows), and sets the variable unimap only if one is found. After that loop, the variable unimap is dereferenced without checking for null.
> Some Mac TrueType fonts have platform IDs 0 (Unicode) and 1 (Mac), but not 3 (Windows).
> At the least, a null check seems required. But more desirable would be support for Mac TrueType fonts.
> Am I missing something, or should I enter a bug?
> Example problem font:
> * Apple Chancery (Included with OS)
> Details:
> * PDFBox version: 1.8.2 [Have not yet tested with 1.8.3, which was released a few days ago]
> * Platform: Mac
> * Java 6
> * Font platform IDs: 0, 1
