-------------------------------------
Summary: Call to Dictionary.encoding throws NullPointerException
for some PDF's
Key: PDFBOX-4878
URL: https://issues.apache.org/jira/browse/PDFBOX-4878
Project: PDFBox
Issue Type: Bug
Components: PDModel
Affects Versions: 2.0.20
Reporter: Thomas Gawehn
Attachments: test.pdf
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):
{{{{}}}}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);
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 ();
{{}}{{ }}
