[jira] [Comment Edited] (PDFBOX-62) Incorrect (zero) character widths returned in some docs

    [ https://issues.apache.org/jira/browse/PDFBOX-62?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13975741#comment-13975741 ]

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

[~tilman] No a bad idea, but as we use some external ttf fonts as substitution for the missing one, we should use their width values as well. I'm working on that.

> 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
