--------------------------------------
Summary: PDFBox not recognizing Auto font size for PDField
Key: PDFBOX-3687
URL: https://issues.apache.org/jira/browse/PDFBOX-3687
Project: PDFBox
Issue Type: Bug
Components: AcroForm
Affects Versions: 2.0.4
Reporter: Scott Coldwell
Attachments: SF1152.pdf, TestSF1152-LL.pdf
See the attached file "SF1152.pdf" and locate the "Bureau" field. If you open
this document in Acrobat the font size shows as Auto and functions as such in
Acrobat/Acrobat Reader. However, PDFBox thinks the font size is set to 9. I
confirmed this in both PDFDebugger and in our rendering code.
The second attachment "TestSF1152-LL.pdf" shows the behavior from PDFBox not
picking up the correct Auto font size. The value is truncated unless you click
inside the field or delete the value and replace it.
The following code shows the problem:
{code}
final PDDocument document =
PDDocument.load(ClassLoader.getSystemResourceAsStream("SF1152.pdf"));
final PDAcroForm form = document.getDocumentCatalog().getAcroForm();
final PDTextField field = (PDTextField)form.getField("Bureau");
final COSDictionary dict = field.getCOSObject();
String defaultAppearance =
((COSString)dict.getDictionaryObject(COSName.DA)).getString();
System.out.println(defaultAppearance);
{code}
results in:
{code}
/Helv 9 Tf 0 0 0.5 rg
{code}
If I manually set the font size to auto using:
{code}
dict.setString(COSName.DA, "/Helv 0 Tf 0 0 0.5 rg");
{code}
the PDF renders correctly.
But we shouldn't have to manipulate font sizes in code when it's set correctly
in the PDF.
