ClassCastException in PDFont.getFontWidth(int)
----------------------------------------------
Key: PDFBOX-976
URL: https://issues.apache.org/jira/browse/PDFBOX-976
Project: PDFBox
Issue Type: Bug
Affects Versions: 1.5.0
Environment: Sun JDK 6u24.
Reporter: Jan Normann Nielsen
Using PDFont.getFontWidth() on a TrueType font fails with ClassCastException in
PDFBox 1.5.0:
Exception in thread "main" java.lang.ClassCastException: java.lang.Integer
cannot be cast to java.lang.Float
at org.apache.pdfbox.pdmodel.font.PDFont.getFontWidth(PDFont.java:786)
at
org.apache.pdfbox.pdmodel.font.PDSimpleFont.getFontWidth(PDSimpleFont.java:191)
at org.apache.pdfbox.pdmodel.font.PDFont.getStringWidth(PDFont.java:283)
at ...
This is due to PDTrueTypeFont.loadDescriptorDictionary(...) loading a
non-generic List of Integer instances (lines 342-355) and then calling
setWidths() with that list in line 356. But the list has been declared as
List<Float>. PDFont.getFontWidth(int) then fails in line 786 with that the
exception.
