Thomas Gawehn updated PDFBOX-4878:
----------------------------------
Description:
Wenn iterating all fonts in a PDF a call to
PDSimpleFont.getEncoding().getEncodingName () throws a NullPointerException
inside the library code for the attached sample-PDF.
The situation can be reproduced, when running the following loop for the
attached PDF (test.pdf):
{code:java}
PDDocument document = PDDocument.load (file);
int pages = document.getNumberOfPages ();
for (int i = 0; i < pages; ++i)
{
PDPage page = document.getPage (i);
PDResources resources = page.getResources ();
if (resources == null)
continue;
Iterator<COSName> iter = resources.getFontNames ().iterator ();
while (iter.hasNext ())
{
COSName cos = iter.next ();
try
{
PDFont font = resources.getFont (cos);
System.out.println (font.getName ());
if (font instanceof PDSimpleFont)
{
PDSimpleFont simpleFont = (PDSimpleFont) font;
Encoding encoding = simpleFont.getEncoding ();
if (encoding != null)
{
try
{
System.out.println ("*
encoding="+encoding.getEncodingName ());
}
catch (Exception e)
{
e.printStackTrace ();
}
}
}
}
catch (IOException e)
{
e.printStackTrace ();
}
}
}
document.close ();
{code}
