------------------------------------------

Thanks for your report. As I can't reproduce the described behaviour, I'd like to know which version you are using? Am I right that it is an older one like 0.7.x? The current trunk version produces an other error, because of some issue with the embedded truetype font:

java.lang.NullPointerException

	at org.apache.pdfbox.pdfviewer.PageDrawer.processTextPosition(PageDrawer.java:174)

> For certain PDF documents (such as the one attached) 
> the character/string widths (as obtained e.g. by the 
> PDFont.getStringWidth method) are not returned 
> correctly, i.e. they appear to be correct for punctuation 
> characters but are zero for alphanumeric characters.  
> It seems as if these alphanumeric characters are NOT 
> within PDFont.firstChar and PDFont.lastChar in the 
> Type 1 font.  The method therefore attempts to obtain 
> the font widths from the AFM (font metric) file, but fails 
> (silently) with a 'resource is null' logline message.
> (Note that this problem doesn't seem to occur with Type 
> 1 fonts in other documents.)
> A more detailed discussion regarding this issue can be 
> found in this link:
> http://sourceforge.net/forum/forum.php?
> thread_id=1260349&forum_id=267205
> Thanks in advance for any help that can be obtained,
> Tam
