Tilman Hausherr commented on PDFBOX-2133:
-----------------------------------------
This is the beginning of the private dict:
{code}
dup /Private 23 dict dup begin
/-| {string currentfile exch readstring pop} executeonly def
/|- {noaccess def} executeonly def
/| {noaccess put} executeonly def
/BlueScale 0.061 def
/BlueShift 7.1 def
{code}
According to the
[spec|http://partners.adobe.com/public/developer/en/font/T1Format.pdf]
BlueShift should be an integer and the default is 7.
{code}
else if (key.equals("BlueScale"))
{
font.blueScale = value.get(0).floatValue();
}
else if (key.equals("BlueShift"))
{
font.blueShift = value.get(0).intValue();
}
else if (key.equals("BlueFuzz"))
{
font.blueScale = value.get(0).intValue();
}
{code}
Btw, the BlueFuzz value is assigned to bluescale.

> Key: PDFBOX-2133
> URL: https://issues.apache.org/jira/browse/PDFBOX-2133
> Project: PDFBox
> Issue Type: Bug
> Components: FontBox
> Affects Versions: 2.0.0
> Reporter: Petr Slaby
> Assignee: John Hewson
> Priority: Minor
> Attachments: 000116.pdf, 000304.pdf, testrun.log
>
>
> When rendering the attached PDF, parsing of a font fails with a
> NumberFormatException. Many NullPointerExceptions and "missing fonts" are
> being reported then. The PDF rendered fine in our modified 1.7.x where fonts
> were read using AWT. I did not try with current 1.8.x. Stack traces are
> attached.
> Note: This is just a file from my test suite, not a production problem. I am
> not sure whether the parser or the PDF is wrong, but the fact that it renders
> fine in Acrobat and in 1.7.x indicates that the former is true. The offending
> font is F2, if I catch and ignore the runtime exception in
> PDResources#getFonts() then it is reported as missing in the PageDrawer.
