[jira] [Commented] (PDFBOX-1664) NullPointerException in PDType1Font.java

["Tilman Hausherr (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/PDFBOX-1664?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13746093#comment-13746093 ] 

Tilman Hausherr commented on PDFBOX-1664:
-----------------------------------------

I found the cause, it is a syntax error in the PDF file:

<<
/Type /FontDescriptor
/Ascent 720
/CapHeight 660
/Descent -270
/Flags 32
/FontBBox [-177 -269 1123 866]
/Fontname /Helvetica-Bold
/ItalicAngle 0
/StemV 105
>>

The "n" in /Fontname should be in capitals. If I correct it then it works fine. The Adobe PDF reference tells that it is case sensitive (page 46), although it seems that their viewer does render the "bad" file properly.

> The cause [as of 19.8.2013] is in PageDrawer.java:
>     awtFont = FontManager.getAwtFont(fd.getFontName());
> which fails because fd.getFontName() returns null.
> A fix (don't know if it is good or just the symptom) is to add this line above:
>     if (fd.getFontName() != null)
> It happens with 1.8.2, and the 2.0.0 version that I downloaded on May 5th.
> I can't provide a file, because its confidential.
> [memo for me: it is file 287]
