Ben Root commented on PDFBOX-62:
--------------------------------
Hello,
I have just downloaded pdfbox-app-1.7.0.jar and began to use it in my
application. I encountered a similar zero character width problem. I loaded the
file that Tamir attached (5542.pdf) using the following code snippet and found
that the printed document had a number of zero width characters which appear as
points where multiple characters overwrite each other.
Begin Code
final PDDocument loaded = PDDocument.load(new
File("/Users/ben/Desktop/5542.pdf"));
loaded.silentPrint();
End Code
Thanks for any light you can shed on this!
Best,
Ben

> 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:

> Thanks in advance for any help that can be obtained,
